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 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 ...

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 ...

NICE, FRANCE — The use of adenosine to identify and eliminate dormant pulmonary vein conduction during radiofrequency ablation of paroxysmal atrial fibrillation (AF) significantly reduces recurrent ...

I have always assumed that atrial fibrillation means that both atria are in a quiver. Is it possible for only one atrium to be in fibrillation while the other is in a normal sinus rhythm, atrial ...

Compared with an age, sex, and region-matched general population, patients hospitalized for AF or atrial flutter had, on average, a 2.6-year loss in life expectancy. When different age groups were ...

What is the electrophysiologic mechanism of atrioventricular reentrant tachycardia (AVNRT)? AVNRT is the most common narrow-complex tachycardia in healthy individuals and only second to atrial ...

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, ...
