this double-blind controlled study examined the frequency of ventricular arrhythmias ( premature ventricular contractions ( pvcs ) greater than 5.min-1 , bigeminy , couplets , ventricular tachycardia , and ventricular fibrillation ) in coronary artery bypass graft ( cabg ) patients during the first 24 hr postoperatively to determine the effect of prophylactic lidocaine on reducing the frequency of ventricular arrhythmias .
