The American Journal of Cardiology, 1971 Ventricular fibrillation is the most common mechanism of sudden unexpected cardiac death in persons with asymptomatic or symptomatic coronary artery disease. The electrophysiologic mechanisms reviewed in this article include: automaticity of pacemaker fibers, transformation of nonpacemaker into pacemaker fibers, "injury" currents and reentry.

Long QT syndrome provoked by induction of general anesthesia -A case report- [PDF]
Korean Journal of Anesthesiology, 2010 Long QT syndrome (LQTS) is an arrhythmogenic cardiovascular disorder resulting from mutations in cardiac ion channels. LQTS is characterized by prolonged ventricular repolarization and frequently manifests itself as QT interval prolongation on the ...

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 ...

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

Vulnerability to ventricular fibrillation [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1998 One of the factors that favors the development of ventricular fibrillation is an increase in the dispersion of refractoriness. Experiments will be described in which an increase in dispersion in the recovery of excitability was determined during brief episodes of enhanced sympathetic nerve activity, known to increase the risk of fibrillation.

Potential Application of Pulsed Field Ablation in Ventricular Arrhythmias
Medicina, 2023 Pulsed field ablation (PFA) is a new ablative method for the therapy of arrhythmia. Recent preclinical and clinical studies have already demonstrated the feasibility and safety of PFA for the treatment of atrial fibrillation (AF).
