Atrial fibrillation, or AFib, is a type of arrhythmia, or irregular heartbeat, and is a disease of the electrical system of the heart. The heart has two upper chambers, called atria, and two lower ...

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 ...

Atrial fibrillation occurs when cardiac electrical impulses become disordered, leading to a rapid and irregular heartbeat. Lip and colleagues discuss the mechanisms that underlie this common ...

There is a link between atypical heart sounds and atrial fibrillation. People with this condition have an irregular, disorganized heartbeat. Atrial fibrillation is a serious type of arrhythmia, which ...

Management of AF from a rate control or rhythm control perspective has been studied via a meta-analysis of 5 randomized trials. 7 Rate control in combination with anticoagulation as front-line ...

Investigating breast cancer and atrial fibrillation overlap, this study highlights key risk factors, underscoring the need ...

Atrial tachycardia is an abnormal heart rhythm where the top chambers in your heart beat quicker than usual. During an atrial tachycardia episode, your heart rate may exceed 100 beats per minute (bpm) ...

In this prospective, multicenter clinical trial, we randomly assigned patients with symptomatic, drug-resistant atrial fibrillation, an ejection fraction of 40% or less, and New York Heart Association ...

What is atrial fibrillation, and why has Apple decided that it’s worth screening for it? The first question is much easier to answer, so let’s get that out of the way. Your heart has four chambers, ...

Atrial fibrillation, or afib, is a type of heart arrhythmia — or irregular heartbeat — caused by abnormal electrical signals in the upper chambers of your heart (atria). These erratic electrical ...

There is a wide range of available treatments for atrial fibrillation. Patients may be entirely treated by their GP (general practitioner, primary care physician), while others may require the ...
