Arrhythmia heart disease classification using deep learning
Arrhythmia affects millions of people in the world. Sudden cardiac death is the cause about half of deaths due to cardiovascular disease and about 15% of all deaths globally. About 80% of sudden cardiac death is the result of ventricular arrhythmias. Arrhythmias may occur at any age but are more …

Neural Network Pruning for ECG Arrhythmia Classification
… and compared on the CIFAR-10 database and an ECG arrhythmia classification task. Each pruning method employs a pruning phase interleaved with a finetuning phase. It is shown that when performing the scale-factor pruning algorithm on ECG, finetuning time can be expedited by 1.4 times over the …

Study of the Kalman filter for arrhythmia detection with intracardiac electrograms
… pacing. The schemes for detecting cardiac arrhythmias often realize nonpathologic tachycardia as serious arrhythmias and deliver false shocks. In this study, an arrhythmia classification technique has been developed with the use of Kalman filter applied on cyclostationary autoregressive …

Arrhythmia mechanisms in acute ischaemia and chronic infarction in rabbit heart
… acute coronary infarction and the occurrence of arrhythmias. The electrophysiology of the epicardial surface of isolated hearts was examined using the voltage sensitive dye RH237 and optical action potentials were recorded from a 13x13mm area of left ventricular epicardium using a 16x16 element …

Proactive and Reactive Aggression, Respiratory Sinus Arrhythmia, and Sleep in Adolescents
… this further, investigating if respiratory sinus arrhythmia (RSA), a biomarker for emotion regulation and parasympathetic-mediated cardiac activity, was mediating the relationship between sleep and aggression among a sample of adolescents. The results of the study revealed that although sleep …

Respiratory Sinus Arrhythmia and Restricted Repetitive Behaviors in Autism Spectrum Disorder
… exclusive. This study used respiratory sinus arrhythmia (RSA) patterns in children with and without an ASD diagnosis as an indicator of ANS functioning to analyze its relationship to the manifestation of RRBs. Baseline RSA and RSA reactivity were found to predict RRB severity and exploratory …

CyberCardia: Patient-specific electrophysiological heart model for assisting left atrium arrhythmia ablation
Atrial arrhythmia can be categorized into tachycardia, flutter, and fibrillation. Atrial fibrillation is a prevalent heart disease that results in weak and irregular contractions of the atria. It affects millions people worldwide and contributes to hundreds of thousands deaths annually. Cardiac …

Folate Receptor-Targeted Transplacental Delivery of Digoxin for the Treatment of Fetal Arrhythmia
Fetal tachyarrhythmias is one of the leading causes of fetal hydrops and, ultimately, fetal demise. This condition is typically treated with transplacental digoxin by maternal administration. However, maternal digoxin administration is associated with nausea, vomiting, heart block and sinus …

Signal Processing for Early Warning Arrhythmia Detection and Survival Prediction for Clinical Decision
… a vast majority of people start showing cardiac arrhythmia-related symptoms which, if not treated in time may lead to a serious heart condition or even sudden cardiac death. To identify the early-warning signs in cardiac arrhythmia, methods to identify the precursors to fatal arrhythmia were …

The relationship between repolarisation alternans and the production of ventricular arrhythmia in heart failure
… is thought to predict the risk of ventricular arrhythmias in patients with heart disease, although recent clinical studies have conflicting results. Understanding the cellular basis for alternans may not only inform more effective utilisation of the clinical test, but also provide new insights …

AI-DRIVEN ATRIAL ARRHYTHMIA DETECTION: DEVELOPMENT, CROSS-COMPARISON AND UNCERTAINTY QUANTIFICATION OF ALGORITHMS FOR CLINICAL CONTINUOUS ECGS
Background: Atrial arrhythmias, particularly atrial fibrillation (AF), are prevalent cardiovascular disorders characterized by irregular heart rhythms originating from the atria, and affecting approximately 2-3% of the global population. These conditions are associated with increased risks of …

High Resolution Multi-parametric Diagnostics and Therapy of Atrial Fibrillation: Chasing Arrhythmia Vulnerabilities in the Spatial Domain
… the body. Ablative therapy for atrial tachyarrhythmias is growing in acceptance. However, ablation procedures can be complex, leading to varying levels of recurrence, and have a number of serious risks. The high recurrence rate could be due to the difficulty of accurately predicting where to …

Mediating and Moderating Effects of Child Respiratory Sinus Arrhythmia Reactivity in the Association Between Early Childhood Adversity and Later Adjustment
… control, can be measured by Respiratory Sinus Arrhythmia Reactivity (RSA-R). This study examined whether RSA-R mediates and moderates the relation between childhood adversity (e.g., stressful events, low-income, parental psychopathology) and adjustment (externalizing problems, internalizing …

A novel means of cardiac catheter guidance for ablation therapy of ventricular tachycardia
… VT but do not prevent the initiation of the arrhythmia. Alternatively, the radiofrequency (RF) ablation procedure has been recently used as a potentially curative therapy by delivering a high-frequency current at the arrhythmia site in order to disrupt the re-entrant circuit and to prevent …

Respiratory Sinus Arrhythmia and Emotional Responding to Dyadic Discussions of a Disagreement as Predictors of Helping Related Subjective Well-Being in Older Mothers and Their Adult Daughters
… well as baseline measures of respiratory sinus arrhythmia were considered as predictors of mothers' and daughters' satisfaction with their helping relationships. Relationship satisfaction was measured by considering mothers' and daughters' subjective well-being specifically in regards to the …

Arrhythmias in Pulmonary Hypertension
Cardiac arrhythmias are common in patients with pulmonary arterial hypertension (PAH) due to structural and electrical remodelling of the right heart, and are associated with adverse clinical outcomes. This study investigated the prevalence and clinical significance of conduction abnormalities and …
