Trends in quantitative methods used for atrial fibrillation and ventricular tachycardia analyses

Informatics in Medicine Unlocked, 2017
Background: Improved quantitative and computational research efforts would be useful for better and more accurate analysis of heart arrhythmias, and to target catheter ablation sites.

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 ...

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 ...

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

Characterisation of the Na, K pump current in atrial cells from patients with and without chronic atrial fibrillation [PDF]

, 2003
<b>Objective:</b> To assess the contribution of the Na, K pump current (<i>I</i>_p) to the action potential duration (APD) and effective refractory period (ERP) in human atrial cells, and to investigate ...

Ventricular Fibrillation [PDF]

Circulation: Arrhythmia and Electrophysiology, 2017
See Article by Panitchob et al > As to the fundamental mechanisms of fibrillation we have plenty of theories, but none is universally accepted… we may note in passing that they all center around two ideas … (a) that the impulses arise from centers or pacemakers, or (b) that the condition is caused by re-entry of impulses and the formation of circles ...

Unexpected Lethal Complication of Ventricular Fibrillation in Symptom Free Variant Angina Pectoris

Journal of Arrhythmia, 2005
We report an unexpected sudden cardiac death due to variant angina complicated by ventricular fibrillation occurring during routine ambulatory electrocardiographic monitoring.

New model of ventricular fibrillation [PDF]

Journal of Electrocardiology, 2005
The purpose of this study was to develop a more efficient and stable model of ventricular fibrillation (VF) in the isolated rabbit heart, because there is not a satisfactory model with this animal. We also observed the effects of increasing extracellular calcium in the stability and reversibility of the arrhythmia.
