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 ...

Atrial flutter and atrial fibrillation (AFib) both occur when the electrical signals that make your heart chambers contract occur faster than typical. However, they differ in the organization of ...

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 ...

Atrial flutter occurs when a “reentrant” circuit is present, causing a repeated loop of electrical activity to depolarize the atrium at a rate of about 250 to 350 beats per minute; the atrial rate in ...

Amiodarone is effective in maintaining sinus rhythm in atrial fibrillation but is associated with potentially serious toxic effects. Dronedarone is a new antiarrhythmic agent pharmacologically related ...

Atrial flutter is an abnormal heart rhythm where the upper heart chambers beat too fast, reducing the heart’s ability to pump blood effectively and potentially leading to heart muscle damage, stroke, ...

Atrial flutter is a heart disorder in which the heart beats out of its normal rhythm. The condition is similar to atrial fibrillation (afib) — the most common type of arrhythmia (abnormal heartbeat) — ...
