Management of Atrial Flutter

Contemporary management of atrial flutter.

A60-year-old dentist presents to the emergency room with palpitations for 3 hours. The ECG shows atrial flutter (AFl) with atrioventricular (AV) conduction varying from 2:1 to 4:1. He has known hypertension for which he takes 10 mg of enalapril daily. In the last 2 years he was seen twice because of AFl and on both occasions 1 mg of ibutilide IV resulted in the return of sinus rhythm with 1:1 A...

Atrial flutter.

was attempted in eight patients with drug refractory type I atrial flutter. In seven of eight patients, a zone of prolongation and fragmentation of the endocardial electrogram was found in the low posterior part of the right atrium. Entrainment of the atrial flutter by high right atrial pacing was accompanied by local recording of second-degree regional block in several atrial sectors but never...

Characterization of Atrial Flutter

Studies were performed using bipolar atrial wire electrodes to record atrial electrograms and to pace the atria in 27 patients who developed atrial flutter after open heart surgery. Two types of atrial flutter, classic or type I atrial flutter, and type II atrial flutter, were identified. Both types of atrial flutter were characterized by uniformity of the beat-to-beat atrial cycle length, morp...
