Atrial flutter is a type of abnormal heart rate. It occurs when the upper chambers of your heart beat too fast. Learn about symptoms and risk factors.

Atrial fibrillation is when your heartbeat is irregular and often very fast. It's similar to but not the same as an atrial flutter - both are abnormal heart rhythms, but the heart's atria beat ...

Atrial flutter is a disorder which causes the heart to beat out of its normal rhythm. Learn more here.

Narrow QRS complexes occur regularly. This tracing suggests either atrial flutter or ventricular tachycardia. It is not atrial flutter, however. If it were, the QRS complexes occurring regularly ...

Atrial fibrillation symptoms vs. flutter Atrial flutter is another type of abnormal heart rhythm. It happens when a short circuit causes the upper chambers of your heart (atria) to pump too fast.

Radiofrequency ablation should be considered as first-choice therapy for symptomatic atrial flutter, even after just one episode, investigators conclude. An accompanying editorial, however ...

A trial of a gold-tipped contact force-sensing catheter for treatment of patients with atrial flutter met its primary endpoints, researchers reported at AF Symposium. For the prospective ...
