New research findings from the University Medical Center Göttingen (UMG) show that both atria undergo profound changes in ...

Atrial fibrillation (AF or afib) involves abnormal electrical activity in the upper chambers (atria) of your heart, which causes the organ to beat quickly and irregularly. This abnormal beating ...

Investigators evaluated the incidence of asymptomatic cerebral emboli and cognitive outcomes in patients receiving pulsed field ablation for AF.

Atrial fibrillation, or AFib, is the most common heart rhythm disorder in the world, affecting more than 6 million Americans.

According to research presented at Heart Rhythm 2026, GLP-1 RA therapy is associated with decreased risk for atrial fibrillation.

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 ...

Atrial fibrillation occurs and maintains itself in the context of a morphologically and functionally altered atrial substrate that can be induced by stressors such as underlying diseases (cardiac or ...

ECG aberrancy means the heartbeat does not follow the usual conduction system of the heart. Atrial fibrillation with ECG aberrancy means people have an irregular heart rhythm with abnormal conduction.

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.
