Abstract

Different mechanisms of block of impulse propagation in several re-entrant circuits resulted in a major discordance between the "echo-zone" and the "tachycardia-zone" in a patient with intermittent Wolff-Parkinson-White syndrome, dual atrioventricular nodal pathways, and bundle branch re-entry. This case illustrates the delicate balance in electrophysiological properties required between the tissues incorporated in a re-entrant circuit to initiate and sustain the arrhythmia. It also shows how the presence of several reentrant pathways can lead to refractoriness in the circuit responsible for the circus movement tachycardia.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.
