The use of right atrial stimulation in the treatment of atrial flutter was evaluated in 10 patients. Atrial flutter was present in these patients from 6 to 96 hr before the procedure. Eight patients were receiving digitalis preparations. In seven patients a unipolar platinum-tipped electrode was positioned in the right atrium by monitoring the intra-atrial electrocardiogram; in three patients a bipolar pacing catheter was positioned in the right atrium under fluoroscopic guidance. Atrial stimulation was performed utilizing either a battery-powered or electrically powered pulse generator. Right atrial stimulation was performed at 180/min in seven patients and 400 to 600/min in three patients. Right atrial stimulation produced conversion to a stable sinus rhythm in seven patients and a transient sinus rhythm in an additional patient. In all but one patient transient unstable atrial fibrillation was observed immediately before conversion to a sinus mechanism. Postconversion arrhythmias or complications directly attributed to the procedure were not observed. In certain patients with atrial flutter-especially those unable to tolerate anesthesia, large doses of antiarrhythmic drugs, or withdrawal from digitalis—atrial stimulation seems to be the initial treatment of choice.
