Coronary vasospasm as an etiology of recurrent ventricular fibrillation in the absence of coronary artery disease: a case report

open access: yesJournal of Community Hospital Internal Medicine Perspectives, 2021
Background: Vasospastic angina (VA), or Prinzmetal’s angina, is characterized by symptoms of coronary angina caused by coronary vasospasm, usually in the absence of atherosclerotic changes.

Vulnerability to ventricular fibrillation [PDF]

open access: yesChaos: 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.

Long QT syndrome provoked by induction of general anesthesia -A case report- [PDF]

open access: yesKorean 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 ...

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

open access: yesThe 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 ...

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

open access: yesHospital 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 ...

Mechanisms of Ventricular Fibrillation

open access: yesJapanese 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 ...
