Defibrillation via the Elimination of Spiral Turbulence in a Model for Ventricular Fibrillation [PDF]

Physical Review Letters, Vol. 86, 3678-3681 (2001), 2001
Ventricular fibrillation, the major reason behind sudden cardiac death, is turbulent cardiac electrical activity in which rapid, irregular disturbances in the spatiotemporal electrical activation of the heart makes it incapable of any concerted pumping action.

Modern clinical retrospective on ventricular rhythm disturbances in acute myocardial infarction: Latest treatment mode according to the valid recommendations [PDF]

Hospital Pharmacology, 2015
Ventricular arrhythmias are the most common cause of mortality in patients with acute myocardial infarction. Arrhythmias in acute coronary syndrome occur because of unbalanced function of the autonomic nervous system, because of electrolyte status ...

Atrial fibrillation and electrophysiology in transgenic mice with cardiac-restricted overexpression of FKBP12 [PDF]

, 2019
Cardiomyocyte-restricted overexpression of FK506-binding protein 12 transgenic (αMyHC-FKBP12) mice develop spontaneous atrial fibrillation (AF). The aim of the present study is to explore the mechanisms underlying the occurrence of AF in αMyHC-FKBP12 ...

Explainable artificial intelligence for heart rate variability in ECG signal

Healthcare Technology Letters, 2020
Electrocardiogram (ECG) signal is one of the most reliable methods to analyse the cardiovascular system. In the literature, there are different deep learning architectures proposed to detect various types of tachycardia diseases, such as atrial ...

Single beat determination of intraventricular systolic dyssynchrony in paitents with atrial fibrillation and systolic dysfunction [PDF]

, 2013
Background:: Atrial fibrillation (AF) is the most common clinically significant cardiac arrhythmia. However, diagnosis of intraventricular dyssynchrony in patients with AF is difficult due to beat-to-beat variation. Additionally, evaluation of mechanical

Mechanisms of Ventricular Fibrillation

Japanese Heart Journal, 1966
Transition from a regular supraventricular or ventricular mechanism to fibrillation was recorded utilizing 2 ultramicroelectrodes.Fibrillation in the hypothermic dog heart was preceded by asynchronous repolarization of individual fibers. An early premature beat caused incomplete depolarization of some fibers (local block) and irregular spread of ...

Early Repolarization Pattern and Idiopatic Sustained Monomorphic Ventricular Tachycardia: an Infrequent Combination

Journal of Cardiac Arrhythmias, 2021
Malignant early repolarization as cause of sudden death has taken on great importance in recent years. It has been described as an entity capable of producing ventricular arrhythmic events, causing from episodes of syncope to sudden cardiac death ...

Catheter ablation of idiopathic ventricular fibrillation using the CARTO 3 mapping system

The Egyptian Heart Journal, 2015
Ventricular fibrillation in the absence of structural heart disease represents an important mechanism of sudden cardiac death. It is initiated by triggers originating in the distal Purkinje fibers, arising from either the right or the left ventricle ...

Left ventricular diastolic dysfunction and N-terminal probrain sodium-uretic peptid level in patients with atrial fibrillation [PDF]

Medičnì Perspektivi, 2013
In our study 100 consecutive non-valvular permanent atrial fibrillation patients with NYHA I – III heart failure, 43 - 86 years old (65 men and 35 women) were examined. Control group consisted of 30 patients with arterial hypertension and coronary artery
