Abstract

Atrial fibrillation (AF) is a major cause of morbidity in the aging population. Initially preponderant in men over age 60, it ultimately becomes a disease of women, in part perhaps because of their greater longevity. The subject of AF is an extremely complex one, as described in this article. The author deals with atrial size and atrial pressure, atrial structure, and electrophysiologic correlates of chronic AF in human subjects. He also discusses pacing-induced models of AF and ionic determinants of pacing-induced AF. He emphasizes the changes that occur in the atrium as a result of rapid rate and/or fibrillation and the interdependence of AF and changes in myocardial structure.

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.
