Improved Cardiac Arrhythmia Prediction Based on Heart Rate Variability Analysis [PDF]

open access: yes, 2022
Many types of ventricular and atrial cardiac arrhythmias have been discovered in clinical practice in the past 100 years, and these arrhythmias are a major contributor to sudden cardiac death. Ventricular tachycardia, ventricular fibrillation, and paroxysmal atrial fibrillation are the most commonly-occurring and dangerous arrhythmias, therefore early ...

Role of Oxidative Stress in the Genesis of Ventricular Arrhythmias

open access: yesInternational Journal of Molecular Sciences, 2020
Ventricular arrhythmias, mainly lethal arrhythmias, such as ventricular tachycardia and fibrillation, may lead to sudden cardiac death. These are triggered as a result of cardiac injury due to chronic ischemia, acute myocardial infarction and various ...

Identifying Ventricular Arrhythmias and Their Predictors by Applying Machine Learning Methods to Electronic Health Records in Patients With Hypertrophic Cardiomyopathy(HCM-VAr-Risk Model) [PDF]

open access: yesThe American Journal of Cardiology, Volume 123, Issue 10, 15 May 2019, Pages 1681-1689, 2021
Clinical risk stratification for sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HC) employs rules derived from American College of Cardiology Foundation/American Heart Association (ACCF/AHA) guidelines or the HCM Risk-SCD model (C-index of 0.69), which utilize a few clinical variables.

Association of Air Pollution with Increased Incidence of Ventricular Tachyarrhythmias Recorded by Implanted Cardioverter Defibrillators [PDF]

open access: yes, 2005
Epidemiologic studies have demonstrated a consistent link between sudden cardiac deaths and particulate air pollution. We used implanted cardioverter defibrillator (ICD) records of ventricular tachyarrhythmias to assess the role of air pollution as a ...

Classification of Arrhythmia by Using Deep Learning with 2-D ECG Spectral Image Representation [PDF]

open access: yesRemote Sensing. 2020; 12(10):1685, 2020
The electrocardiogram (ECG) is one of the most extensively employed signals used in the diagnosis and prediction of cardiovascular diseases (CVDs). The ECG signals can capture the heart's rhythmic irregularities, commonly known as arrhythmias. A careful study of ECG signals is crucial for precise diagnoses of patients' acute and chronic heart ...

A KATP channel opener inhibited myocardial reperfusion action potential shortening and arrhythmias [PDF]

open access: yes, 2001
Low concentrations of certain K<sub>ATP</sub> channel openers have been reported to exert a moderate inhibitory effect on arrhythmias during post-ischaemic early myocardial reperfusion, but the accompanying effects on the time course of ...
