New ideas about atrial fibrillation 50 years on

Abstract

Atrial fibrillation is a condition in which control of heart rhythm is taken away from the normal sinus node pacemaker by rapid activity in different areas within the upper chambers (atria) of the heart. This results in rapid and irregular atrial activity and, instead of contracting, the atria only quiver. It is the most common cardiac rhythm disturbance and contributes substantially to cardiac morbidity and mortality. For over 50 years, the prevailing model of atrial fibrillation involved multiple simultaneous re-entrant waves, but in light of new discoveries this hypothesis is now undergoing re-evaluation.

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.

Atrial Filbrillation

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

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.
