▼ The surface electrocardiogram (ECG) is a periodic signal portraying the electrical activity of the heart from the torso. The past fifty years have witnessed a proliferation of computer algorithms destined for ECG analysis. Signal averaging is a noise reduction technique believed to enable the surface ECG to act as a non-invasive surrogate for cardiac electrophysiology. The P wave and the QRS complex of the ECG respectively depict atrial and ventricular depolarization. QRS detection is a pre-requisite to P wave and QRS averaging. A novel algorithm for robust QRS detection in mice achieves a four-fold reduction in false detections compared to leading commercial software, while its human version boasts an error rate of just 0.29% on a public database containing ECGs with varying morphologies and degrees of noise. A fully automated P wave and QRS averaging and onset/offset detection algorithm is also proposed. This approach is shown to predict atrial fibrillation, a common cardiac arrhythmia which could cause stroke or heart failure, from normal asymptomatic ECGs, with 93% sensitivity and 100% specificity. Automated signal averaging also proves to be slightly more reproducible in consecutive recordings than manual signal averaging performed by expert users. Several studies postulated that high-frequency energy content in the signal-averaged QRS may be a marker of sudden cardiac death. Traditional frequency spectrum analysis techniques have failed to consistently validate this hypothesis. Layered Symbolic Decomposition (LSD), a novel algorithmic time-scale analysis approach requiring no basis function assumptions, is presented. LSD proves more reproducible than state-of-the-art algorithms, and capable of predicting sudden cardiac death in the general population from the surface ECG with 97% sensitivity and 96% specificity. A link between atrial refractory period and high-frequency energy content of the signal-averaged P wave is also considered, but neither LSD nor other algorithms find a meaningful correlation. LSD is not ECG-specific and may be effective in countless other signals with no known single basis function, such as other bio-potentials, geophysical signals, and socio-economic trends.

▼ Nowadays stress has become a regular part of life. Stress is difficult to measure because there has been no definition of stress that everyone accepts. Furthermore, if we do not get a handle on our stress and it becomes long term, it can seriously interfere with our health. Therefore, finding the method for stress detection could be beneficial for taking control of stress. Electrocardiogram (ECG) is the measurement of the electrical activity of the heart and represents an established standard in determining the health condition of the heart. The PQRST1[55] complex of ECG conveys information about each cardiac-cycle, where the R-peak is placed in the middle of the PQRST complex and represents the maximum value of the PQRST. Since the PQRST depicts the entire cardio-cycle, the R–peak determines half of the cardio-cycle. The distance between two adjacent R-peaks is defined as a heart rate (HR). The variation of the HR in the specific time frame, defined as heart rate variability (HRV), can reflect the state of the autonomic nervous system (ANS). The ANS has two main divisions, the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The SNS occurs in response to stress while the PNS results from the function of internal organs. The activity of ANS can cause an acceleration (SNS) or deceleration (PNS) of the HR. The SNS activity is associated with the low-frequency range while, the PNS activity is associated with the high frequency component of the HRV. Therefore, the power ratio of the low and high-frequency components of the spectrum of HRV can potentially show whether the subject is exposed to stress or not [48] [50]. In this research, we introduced three new indices, with one of them proposed as a proxy to provide equivalent results in the detection of stress or no-stress states while avoiding complex measurement devices as well as complex calculations. The goal was to find a more time efficient method for fast stress detection which could potentially be used in the applications that run on devices such as a wearable smartwatch in tandem with a smartphone or tablet. The experiment was established to measure the literature proposed index for stress measurement [48][50] as well as our introduced indices. In the experiment, we induced stress to the participants by using mental arithmetic as a stressor [51][53]. Theexperiment contained two kinds of trials. In the first one, the participant was exposed to different amounts of cognitive load induced by doing mental-arithmetic while, in the second one, the participant was placed in a relaxed environment. Each participant in the experiment gave feedback in which period of the experiment he/she felt stress. During the entire experiment, we recorded theparticipant‘s ECG. The ECG was used to calculate HRV which consequently was used for the calculation of the values of the index as proposed from the literature for calculating the level of the stress. The same data was used for the calculation of our introduced indices. The values of our proposed…

▼ Epilepsy is associated with an increased mortality rate. In 7 to 17% of epileptics, the cause of death is unknown and this has been termed sudden unexplained death in epilepsy (SUDEP). Seizure-induced cardiac changes have been implicated in the pathophysiology of SUDEP and impaired autonomic regulation is not uncommon in epilepsy. Epileptic patients generally present with a higher heart rate than healthy individuals and tachycardia is frequently reported during seizure activity. Ictal bradycardia is rare, occurring in ~2% of seizures. It is hypothesised that seizures result in a surge of sympathetic activity which leads to tachycardia and heart damage. SUDEP is more prevalent in males than females and oestrogen is associated with cardio- and neuro- protective effects. Therefore it is expected that seizure severity, arrhythmias and cardiac pathology will be higher in males. In this study, kainic acid (KA, 10 mg/kg, s.c.) was used to induce seizures in male and female Sprague-Dawley rats. Electrocardiograph (ECG), electrocorticograph (ECoG) and behavioural data were recorded simultaneously for 3 hours post KA administration. KA administration resulted in a rapid significant decrease in heart rate (>30%) which lasted for 30-60 min. Bradycardia was associated with hypoactivity and low seizure behaviours. At 100 min post KA dosing, seizure severity increased resulting in an elevated cumulative behavioural seizure score (Level 3+) in conjunction with an increase in heart rate (20%). Wet dog shakes were the most commonly observed behaviour in males while females exhibited higher seizure behaviours such as myoclonic jerks, foaming and rearing. Tonic-clonic seizures were only observed in female KA animals. ECoG traces were analysed by Fast Fourier Transformation of different frequency bands. Females showed greater increases in power across all ECoG frequency bands. The greatest increase occurred in the theta band (4.75-6.75 Hz) which is associated with hippocampal activity. The P wave showed the largest ECG change during seizure activity. In males the P wave duration significantly decreased by 30-40% while no change was observed in females. In females significant decreases in P wave amplitude of up to 50% were observed while no significant changes occurred in males following KA administration. A prolonged PR interval was also present in females during bradycardia and tachycardia. Gender specific alterations in the QTc interval were also observed, with QTc prolongation occurring in males and QTc shortening in females. Histological examination of apical and mid-plane myocardium found that KA induced seizures resulted in left ventricular pathology observed by the presentation of oedema, inflammatory cell infiltration, intra-cardiac haemorrhage and myofibril vacuolisation 48 hours post KA. The results from this study demonstrate that KA induced seizures were associated with altered cardiac activity as observed by heart rate and ECG changes. Seizure induced tachycardia may predispose the subject to fatal arrhythmias and… Advisors/Committee Members: Kerr, Steven (advisor).

▼ Kardiologisten hoitajien EKG:n tulkintataito on merkittävässä asemassa hoidettaessa sydänsairaita potilaita. Kardiologisten hoitajien EKG:n tulkinnassa on isoja vaihteluita. Hoitajien tulee pystyä tulkitsemaan EKG:ssä tapahtuvista muutoksista ja tiedottaa niistä eteenpäin. Hoitajilla tulee olla myös tarvittavat tiedot ja taidot toteuttaa EKG-monitorointi oikein. Kansainvälisiä tutkimuksia kardiologisten hoitajien EKG:n tulkintataidoista on tehty jonkun verran. Kotimaisia tutkimuksia ei tiettävästi ole tehty. Aiheesta tarvitaan lisää tutkittua tietoa. Tutkimuksen tarkoituksena oli kuvata yliopistosairaaloiden kardiologisilla osastoilla työskentelevien hoitajien EKG:n tulkintataitoja. Tämän tutkimuksen kohderyhmän muodostivat Suomen viiden yliopistosairaalan kardiologisilla toiminta-alueilla työskentelevät hoitajat (n=168). Tutkimuksen vastausprosentti oli 18 %. Tämän tutkimuksen aineisto kerättiin sähköisellä e-lomakkeella. Tutkimuksen aineisto analysoitiin tilastollisin menetelmin. Aineiston kuvailussa käytettiin apuna frekvenssi-, prosentti-, keski- ja hajontalukuja. Muuttujien välisten yhteyksien tarkasteluun käytettiin Mann-Whitney U –testiä, Kruskall-Wallisin H –testiä sekä Spearmanin järjestyskorrelaatiokerrointa. Kardiologisten hoitajien tulkintataito oli suhteellisen hyvää. Tulosten mukaan kardiologisilla osastoilla työskentelevien hoitajien EKG osaaminen on heidän oman arviointinsa mukaan erittäin hyvää. Hoitajien EKG:n tulkinta on hyvää. Miehet osasivat tunnistaa naisia paremmin eri EKG-rytmejä (p=0.043). Työpaikalla saadulla koulutuksella (p=0.007) EKG:n tulkintaan ja nykyisellä työpaikalla (p=0.049) oli tilastollisesti erittäin merkitsevä yhteys EKG-osaamiseen. EKG osaamisella ja nykyisellä työpaikalla oli tilastollisesti merkitsevä yhteys. Nykyisellä työpaikalla ja EKG:n tulkinnalla oli tilastollisesti merkitsevä yhteys (p-=0.046). Kardiologisten hoitajien EKG osaamisen ja EKG:n tulkinnan välillä oli tilastollisesti merkitsevä yhteys. Tämän tutkimuksen tuottamaa tietoa voidaan hyödyntää EKG:n tulkintataitojen kehittämiseen ja hoitajien EKG osaamisen sekä EKG:n tulkinnan koulutustarpeen määrittelyyn. Tärkeää olisi kohdentaa EKG-koulutus harjoitusta vaativille osa-alueille. Tärkeää olisi myös järjestää säännöllisiä EKG:n tulkinnan koulutuksia. ABSTRACT Nurses ECG interpretation skills Cardiac nurses ECG skills are in a significant role when looking after cardiac patients. There are great variations of nurses ECG interpretation .Nurses should be able to interpret changes in ECG and report them further. Nurses should also have the necessary knowledge and skills to perform ECG monitoring properly. There are few studies which have been made of cardiac nurses' ECG skills. There are no finnish studies of this topic. More research is needed from this topic. The purpose of the study was to describe the ECG interpretation skills of nurses, who worked in university hospitals cardiology wards. The data of this study consisted of nurses (n = 168), who worked in the cardic areas of five university…

▼ Pre-participation screening (PPS) inclusive of an ECG for young, competitive athletes has been endorsed by the European Society of Cardiology (ESC) and a number of international sporting organisations, in an effort to identify the small number of athletes who may be at increased risk of sudden cardiac death (SCD) due to underlying cardiac conditions such as cardiomyopathies. Whereas most previous reports of the prevalence of ECG abnormalities have been derived from relatively unselected cohorts of young, sub-elite Caucasian athletes, the population undergoing screening in Australia are elite athletes, performing at the highest level in their chosen sports. We screened over 1200 elite Australian athletes to assess the prevalence of abnormal ECG findings in this cohort and whether they identified underlying cardiac abnormalities, to test whether revised ECG criteria improved the accuracy of screening, to examine whether abnormal ECGs were more common in endurance athletes and to explore possible mechanisms for common ECG changes in endurance athletes. Using current criteria for ECG interpretation, almost 1 in 5 elite athletes were classified as having an abnormal ECG, necessitating follow-up to exclude serious cardiac pathology. However, the prevalence of underlying cardiac pathology was very low (0.3%). Applying more refined ECG interpretation criteria, the number of athletes classified as abnormal was reduced to 1 in 20 and the small number with pathology still identified. However, a significant limitation to screening was identified as it was demonstrated that reproducibility of ECG interpretation between experienced physicians was at best moderate, and cardiac pathology missed on 50% of occasions. The patterns and prevalence of ECG changes in indigenous as compared to non-indigenous Australian athletes were evaluated and whilst the overall prevalence of ECG abnormalities was similar, patterns of early repolarisation associated with increased arrhythmic risk were found to be strongly associated with indigenous ethnicity, the significance of which remains uncertain. Abnormal ECGs were twice as prevalent in endurance as compared to non-endurance athletes, largely due to a 3-fold higher prevalence of right precordial T-wave inversions. Utilising cardiac MRI, it is demonstrated that in healthy endurance athletes these T-wave inversions can be explained by cardiac displacement with respect to the surface ECG leads. This thesis identifies limitations in the process of ECG screening which need to be addressed in order to improve the efficacy of screening, confirms the hypothesis that more exercise results in more profound ECG changes, and offers a mechanistic explanation for these findings.

▼ The research over-viewed in this dissertation concerns very accurate variational calculations of the molecular systems with more than two electrons under the assumption of the Born-Oppenheimer (BO) approximation. The centerpiece of this research is the use of explicitly correlated Gaussian (ECG) basis functions with floating centers to generate the potential energy curve (PEC) and potential energy surface (PES) of the considered molecular systems. One challenge of such calculations is the occurrence of the linear dependency between basis functions in the process of basis set optimization. The BO PECs generated with ECG basis sets were limited to two-electron molecular systems for a few decades prior to the implementation of the author's approaches to this issue. These approaches include methods for a partial remedy to linear dependence, better guessing of initial basis functions, permanently removing the restriction of memory usage in parallel computer systems, and efficiently paralleling the calculations. The approach effectively utilizing the super computer systems yields benefits not only to the ECG calculations but could also be useful in the fields that require the significant amount of the computational resources. These procedures were implemented in computer codes that were run quite extensively on several parallel computer systems during the period of the author's Ph.D study. The calculated adiabatic PECs and the rovibrational energy levels are proven to be the most accurate ones to date. The dissertation is primarily based on the content of the papers that were published in co-authorship with my scientific advisor and other collaborators in several scientific journals. It also includes some details that were not considered in the publications but are essential for the completeness and good understanding of the presented work. In order to provide readers an insight into the development of the ECG based BO molecular calculation, the published results of many calculations are classified and presented in a comprehensive way.

▼ Sudden cardiac arrest is often caused by ventricular arrhythmias and these episodes can lead to death for patients with chronic heart disease. Hence, detection of such arrhythmia is crucial in mobile ECG monitoring. In this research, a systematic study is carried out to investigate the possible limitations that are preventing the realisation of a real-time ECG arrhythmia data-mining algorithm suitable for application on mobile devices. Based on the findings, a computationally lightweight algorithm is devised and tested. Ventricular tachycardia (VT) is the most common type of ventricular arrhythmias and is also the deadliest.. A ventricular tachycardia (VT) episode is due to a disorder ofthe regular contractions ofthe heart. It occurs when the human heart ventricles generate a rapid heartbeat which disrupts the regular physiology cycle. The normal sinus rhythm (NSR) of a regular human heart beat signal has its signature PQRST waveform and in regular pattern. Whereas, the characteristics of a ventricular tachycardia (VT) signal waveforms are short R-R intervals, widen QRS duration and the absence of P-waves. Each type of ECG arrhythmia previously mentioned has a unique waveform signature that can be exploited as features to be used for the realization of an automated ECG analysis application. In order to extract this known ECG waveform feature, a time-domain analysis is proposed for feature extraction. Cross-correlation allows the computation of a co-efficient that quantifies the similarity between two times-series. Hence, by cross-correlating known ECG waveform templates with an unknown ECG signal, the coefficient can indicate the similarities. In previous published work, a preliminary study was carried out. The cross-correlation coefficient wave (CCW) technique was introduced for feature extraction. The outcome ofthis work presents CCW as a promising feature to differentiate between NSR, VT and Vfib signals. Moreover, cross-correlation computation does not require high computational overhead. Next, an automated detection algorithm requires a classification mechanism to make sense of the feature extracted. A further study is conducted and published, a fuzzy set k-NN classifier was introduced for the classification of CCW feature extracted from ECG signal segments. A training set of size 180 is used. The outcome of the study indicates that the computationally light-weight fuzzy k-NN classifier can reliably classify between NSR and VT signals, the class detection rate is low for classifying Vfib signal using the fuzzy k-NN classifier. Hence, a modified algorithm known as fuzzy hybrid classifier is proposed. By implementing an expert knowledge based fuzzy inference system for classification of ECG signal; the Vfib signal detection rate was improved. The comparison outcome was that the hybrid fuzzy classifier is able to achieve 91.1% correct rate, 100% sensitivity and 100% specificity. The previously mentioned result outperforms the compared classifiers. The proposed detection and classification algorithm is able to…

A gonadotrofina coriônica equina (eCG) tem sido utilizada em programas de sincronização para inseminação artificial em tempo fixo e normalmente promove o aumento do volume do corpo lúteo e a da produção de progesterona. Além disso, esta mesma gonadotrofina pode ser utilizada para superovulação. Desse modo, hipóteses relativas aos mecanismos pelos quais gonadotrofinas exógenas alteram as funções celulares nos corpos lúteos resultantes foram formuladas. Para testar tais hipóteses, 18 vacas (Bos indicus) foram divididas em grupos: controle (n=5), estimulado (n=6) e superovulado (n=7) e a ovulação das mesmas foi sincronizada usando um protocolo já estabelecido com dispositivo de progesterona. Os animais estimulados receberam 400 UI de eCG no dia de remoção do dispositivo de progesterona e os animais superovulados 4 dias antes. No dia 7 após injeção de GnRh, os animais foram abatidos para a coleta de CLL e sangue. Análises de peso e volume de CL, concentração de progesterona (P4), bem como da expressão gênica e proteica de fatores angiogênicos e de proteínas esteroidogênicas foram realizadas. Além disso, o transcriptoma foi analisado por microarranjo. Foi observado que o volume do CL foi maior nos animais do grupo estimulado (1177,37 ± 167,07 mm3) e ainda maior nos do superovulado (1495,18 ± 137,01 mm3) quando comparados ao grupo controle (830,33 ± 234,99 mm3; p = 0,03). A concentração média de progesterona por CL nos animais do grupo estimulado foi maior que nos animais do grupo controle (5,95 ± 0,17 vs 3,69 ± 0,72 ng/ml; p = 0,03) e que nos superovulados (4,11 ± 0.73; p = 0,01). Além disso, os tratamentos com eCG aumentaram a expressão do FGFR2 e também da STAR nos animais estimulados e superovulados (p < 0,05). Quanto aos resultados do microarranjo, no total 242 transcritos foram aumentados e 111 foram diminuídos nos animais estimulados e 111 foram aumentados e 113 diminuídos nos animais superovulados em relação aos animais controle (~1,5 vezes, p 0.05). Entre os genes diferencialmente expressos, muitos estavam envolvidos na síntese de lipídios e na produção de progesterona, tais como: PPARG, HMGCR, STAR, receptores de prolactina e folistatina. Estes achados demonstraram que os tratamentos com eCG modularam a expressão gênica diferencialmente, dependendo do tratamento, e que nossos dados contribuem para entender as vias relacionadas ao aumento do volume do CL e da produção de progesterona observada após os tratamentos. Em um segundo experimento, foi realizado análises da influência do FSH na expressão de VEGF no cultivo de células da granulosa. Neste experimento foi possível observar que o FSH aumentou a expressão gênica e proteica do VEGF, colaborando com a ideia de que as gonadotrofinas têm propriedades angiogênicas.

Equine chorionic gonadotropin (eCG) has been widely used in synchronization protocol to artificial insemination program and usually promote corpus luteum (CL) volume increases and stimulates progesterone production. Furthermore the same gonadotropin can be used to superovulation protocols. Thus,…

A tarefa mais importante em processamento de sinais de eletrocardiograma (ECG) Ã a determinaÃÃo exata do complexo de QRS, em particular, a detecÃÃo dos picos de onda R atravÃs de sistemas e anÃlises computadorizadas. Ã essencial, especialmente, para uma medida correta da variabilidade do ritmo cardÃaco (HRV). Um grande obstÃculo a ser superado para uma detecÃÃo confiÃvel Ã a sensibilidade do eletrocardiograma a diversas fontes de distÃrbio, tais como, a interferÃncia Ã rede elÃtrica, os artefatos do movimento, flutuaÃÃo da linha base e o ruÃdo dos mÃsculos. Este trabalho utiliza as propriedades matemÃticas da transformaÃÃo de Hilbert sobre wavelets para desenvolver um novo algoritmo capaz de diferenciar as ondas R das demais (P, Q, S, T e U) e facilitar a detecÃÃo dos complexos QRS. Uma taxa de detecÃÃo do complexo QRS de 99,92% Ã alcanÃada para a base de dados de arritmias do MIT-BIH. A tolerÃncia a ruÃdo do mÃtodo proposto foi tambÃm testada usando os registros padrÃo da base de dados MIT-BIH Noise Stress Test. A taxa da detecÃÃo do detector ficou aproximadamente 99,35% mesmo para as relaÃÃes sinal-ruÃdo (SNR) tÃo baixo quanto 6dB.

The most important task in the ECG signal processing is the accurate determina-tion of QRS complex, in particular, accurate detection of the R wave peaks, is essential in computer-based ECG analysis especially for a correct measurement of Heart Rate Variability (HRV). A great hurdle to be overcome in reliable detection is the sensibility of the electrocar-diogram to several disturbance sources such as powering source interference, movement arti-facts, baseline wandering and muscle noise. This study uses the Hilbert Transform pairs of wavelet bases for QRS detection. From the properties of these mathematical tools it was pos-sible to develop an algorithm which is able to differentiate the R waves from the others (P, Q, S, T and U waves).The performance of the algorithm was verified using the records MIT-BIH arrhythmia and normal databases. A QRS detection rate of 99.92% was achieved against MIT-BIH arrhythmia database. The noise tolerance of the proposed method was also tested using standard records from the MIT-BIH Noise Stress Test Database. The detection rate of the detector remains about 99.35% even for signal-to-noise ratios (SNR) as low as 6dB.

As doenças cardiovasculares representam a principal causa de morte em nível mundial, sendo responsáveis por 17,3 milhões de mortes por ano. O eletrocardiograma (ECG) é uma técnica não invasiva utilizada amplamente para a detecção de algumas doenças cardiovasculares. Para aumentar a sensibilidade diagnóstica, o ECG é adquirido em ambulatório ou durante provas de esforço físico. Nessas condições de aquisição é afetado fortemente por vários tipos de ruídos, principalmente pelas flutuações de linha base (FLB). Apesar de existirem vários métodos para a eliminação das FLB, não foi identificado nenhum estudo comparativo que avalie quantitativamente estes métodos usando os mesmos sinais. Neste trabalho foi feita uma caraterização espectral das FLB onde foi comprovado que estas contem componentes espectrais em até 3,14 Hz. Tal valor, entretanto, ultrapassa os valores estabelecidos pela American Heart Association. Adicionalmente, foram implementados nove métodos para a eliminação de FLB os quais são: interpolação usando splines cúbicos, filtragem FIR, filtragem IIR, filtragem adaptativa LMS, filtragem de média móvel, análise de componentes independentes, interpolação e subtração de mediana sucessivas, decomposição em modos empíricos e filtragem wavelet. As técnicas implementadas foram avaliadas de forma qualitativa e quantitativa. Para a avaliação quantitativa foram usadas as seguintes métricas de similaridade: distância máxima absoluta, somatória do quadrado das distâncias e porcentagem da distância do erro médio quadrático. Foram realizados vários experimentos utilizando sinais de ECG sintéticos, ECG reais da QT Database, ruídos artificiais e ruídos reais da Noise Strees Test Database. Os melhores resultados foram obtidos com filtragem FIR passa-altas, com frequência de corte de 0,67 Hz.

Cardiovascular diseases are the leading cause of death worldwide, accounting for 17.3 million deaths per year. The electrocardiogram (ECG) is a non-invasive technique widely used for the detection of cardiac diseases. To increase diagnostic sensitivity, ECG is acquired during exercise stress tests or in ambulatory way. Under these acquisition conditions the ECG is strongly affected by some types of noise, mainly by baseline (BL) wander. Currently in the literature, there are several methods for the elimination of BL, but no comparative study has been found that quantitatively evaluates these methods using the same signals. In this work a spectral characterization of the BL was made where it has been proven that these contain spectral components up to 3.14 Hz which exceeds the values established by the American Heart Association. We also implemented nine methods for the elimination of BL, which are interpolation using cubic splines, FIR filtering, IIR filtering, LMS adaptive filtering, moving average filter, independent component analysis, interpolation and successive median subtractions, decomposition in empirical modes and wavelet filtering. They were evaluated qualitatively and quantitatively. For the quantitative evaluation, the…
