Surface electrocardiographic recognition of dual atrioventricular nodal pathways during sinus rhythm

Abstract

Atrioventricular nodal reentry is the most common mechanism of paroxysmal supraventricular tachycardia. Electrocardiograms obtained during sinus rhythm rarely serve to identify the mechanism of paroxysmal supraventricular tachycardia. We report two cases of dual atrioventricular nodal reentry in which electrocardiograms recorded during sinus rhythm disclosed two separate PR intervals that suggested dual atrioventricular nodal pathways.

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.
