- Abstract
Six patients (5 men, 1 woman) with a history ranging from 3-16 years of resistant vagal atrial arrhythmias wore treated by atrial pacing at a rate of 90/min. These patients have been followed up for an average of 5.5 years (range 2-11 years) with favorable results. The arrhythmias were characterized by daily or weekly attacks of typical atrial flutter and atrial fibrillation occurring mainly or exclusively at night, at rest, or the digestive periods in otherwise normal hearts of middle-aged patients (first attack between 25 and 54. mean 40). The arrhythmias were resistant to quinidine, and were usually aggravated by digitalis, beta-blockers and verapamil. Amiodarone is usually the only effective drug in this syndrome, but was not used before pacing in the 2 first cases, and was ineffective in the other 4 cases. Electrophysiologic studies confirmed the absence of sick sinus syndrome, and the close relationship between a relative bradycardia and the onset of the arrhythmia. Atrial pacing alone totally controlled the arrhythmia in 1 patient; amiodarone was used in conjunction with pacing in 3 patients. In 1 patient the improvement was clear but incomplete, and in 1 patient permanent atrial fibrillation occurred shortly after pacemaker implantation.
