Abstract

The objective of the study was to verify, if the particular sequence of electrical atrioventricular activation during tachycardia is associated with the development of atrial remodelling and predisposition to atrial fibrillation (AF) in patients with nodal reentry tachycardia (AVNRT). We assessed 117 consecutive patients with AVNRT identified during electrophysiological study. Two groups were identified: the AF group, n = 21 (17.9%, median age 46.0, 15 women), with clinically documented AF, and the control group, n = 96, without AF (median age 48.5, 69 women). Tachycardia cycle length (VV), anterograde AV, retrograde VA activation intervals and indexes (AV/VV, VA/VV) during AVNRT, atrial refractory period (AERP), intraatrial (IntraCT) and interatrial conduction time (InterCT) of the sinus beat and premature stimuli were analysed. The longer retrograde and shorter anterograde activation was found in AF patients with typical AVNRT, the opposite relations showed the subjects with atypical tachycardia. Intra and InterCT of sinus beat, and of paced extrastimuli were longer, AERP was borderline shorter in the AF-group than in the controls. The longest conduction times and shortest AERP were seen in the patients with VA/VV within 20-4...Continue Reading

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.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. 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.
