Pacemaker reversion for suspected supraventricular tachycardia. 1985

D L Kuchar, and A M Keogh, and C W Thorburn

Overdrive atrial pacing was employed in twelve patients with suspected supraventricular tachycardia resistant to drug therapy. Eleven of these patients reverted to sinus rhythm with pacing either immediately or after a short episode of atrial fibrillation. In one patient, recordings from the atrial electrode indicated that a broad complex tachycardia was of ventricular rather than supraventricular origin. No complications were encountered and the procedure was well tolerated in all. Overdrive pacing is suggested as a safe alternative to DC cardioversion in drug-resistant supraventricular tachycardia, particularly in the presence of digitalis, in the elderly and in patients with chronic lung disease.

D000368	Aged	A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available.	Elderly
D001282	Atrial Flutter	Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
