Paroxysmal atrial fibrillation with asystole and syncope report of a case of sinus node dysfunction with hypokalemia and hypertension

Abstract

A pattient is presented who developed syncope due to asystole following paroxysmal atrial fibrillation. Suppresion of intrinsic cardiac pacemakers during tachycardia is postulated as the mechanism for asytole. This patient might have sinus node dysfunction. The episodes of tachycardia occurred more often when the serum potassium level was low. © 1976, The Japanese Circulation Society. All rights reserved.
