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 ...

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 ...

Atrial flutter is similar to atrial fibrillation in that the rhythm originates in the atrium and causes a narrow complex tachycardia, which carries thromboembolic risk. Typical atrial flutter results ...

Among the 77 patients assigned to undergo circumferential pulmonary-vein ablation, ablation was repeated because of recurrent atrial fibrillation in 26 percent of patients and atypical atrial flutter ...

Saint-Etienne, France - Radiofrequency ablation is more effective than treatment with amiodarone for the prevention of atrial flutter recurrence in patients who experienced a first symptomatic episode ...

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) — ...
