Abstract:
:A 56-year-old male with atrial fibrillation developed rapid ventricular response up to 200 beats/min or more in the postoperative stage of emergency aortocoronary bypass surgery. Resuscitation for cardiac arrest triggered this rapid ventricular rate. The idea that retrograde conduction into atrioventricular node may prevent ventricular capture of atrial fibrillation was tested. The ventricle was then paced at rapid rate followed by a gradual decrease in the pacing rate to 120 beats/min. By this method, ventricular rate was controlled and hemodynamics stabilized, with more efficiency of intra-aortic balloon counterpulsation. VVI pacing may be used in this manner to control irregular and rapid ventricular response of atrial fibrillation.
