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 ...

Background Previous epidemiological studies demonstrated that premature atrial contractions (PACs) and premature ventricular ...

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

Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...

Dr. Hugh Calkins answers the question: 'Atrial Fibrillation vs. Atrial Flutter?' — -- Question: My doctor told me I sometimes have atrial fibrillation and at other times have atrial flutter. What ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

Dr. Glenn Brammer, a board-certified cardiologist and electrophysiologist, performed the first atrial flutter ablation in Augusta Health’s new Electrophysiology Lab on Oct. 24. Atrial flutter is a ...

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 type of irregular heartbeat, or an arrhythmia. It causes your heart to beat too fast. Atrial flutter doesn't always have symptoms, but it can sometimes have serious consequences if ...

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) — ...
