It is common practice to restore and maintain sinus rhythm in patients with atrial fibrillation and heart failure. This approach is based in part on data indicating that atrial fibrillation is a ...

The development of atrial fibrillation (AF) and atrial enlargement are intimately linked: persistent AF leads to atrial distension and, conversely, atrial enlargement in patients with hypertension or ...

Maintenance of sinus rhythm is the main therapeutic goal in patients with atrial fibrillation. However, recurrences of atrial fibrillation and side effects of antiarrhythmic drugs offset the benefits ...

Here, we describe a large four-generation family with an autosomal dominant condition, comprising various types of CHD and low atrial rhythm, a unique phenotype not described before within a family. A ...

The rhythm is either sinus rhythm or not sinus rhythm. Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node, or SA node.

Atrial fibrillation is a common management challenge in the elderly patient. It has been estimated that 8%-10% of patients over the age of 80 will be in atrial fibrillation. It is difficult to call ...

The management of atrial fibrillation (AF) focuses on control of heart rate, correction of rhythm disturbance, prophylaxis of thromboembolism, treatment of underlying disorders, and pathophysiologic ...

Atrial fibrillation and ventricular fibrillation are both types of irregular heartbeats (arrhythmias). Atrial fibrillation (AFib) affects the two upper chambers of your heart. Ventricular fibrillation ...

An arrhythmia (pronounced as “uh-RITH-me-uh”) is an irregular heartbeat. This means your heart is out of its usual rhythm. About 1.5%-5% of people have arrhythmias. It may feel like your heart skipped ...

When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...
