| dc.description | Antiarrhythmic properties of N-acetylprocainamide, an active metabolite of procainamide, were studied in 15 patients who presented with a cardiac arrest or documented sustained ventricular tachycardia. Programmed electrical stimulation studies were performed. All patients tested had inducible ventricular tachycardia by programmed electrical stimulation techniques while off all antiarrhythmic therapy. Patients were then tested on procainamide 1000 mg administered intravenously, and ventricular tachycardia could be provoked in 8 of 10 patients. Twenty-four to 36 hours later, N-acetylprocainamide was administered, intravenously, and programmed stimulation was performed after 20 minutes. N-acetylprocainamide did not significantly change heart rate, mean arterial blood pressure, electrocardiographic intervals, A-H or H-V conduction times. N-acetylprocainamide prevented ventricular tachycardia induction in 6 of 15 patients. The mean serum N-acetylprocainamide levels in the group protected was 15.7+4 μg/ml and 16.2+4 μg/ml in the group nonprotected. These 6 patients were discharged on N-acetylprocainamide 1.5 grams orally every 8 hours. Three patients have been maintained on chronic N-acetylprocainamide every 8 hours. Three patients have been maintained on chronic N-acetylprocainamide therapy (6+2 months), two patients had breakthrough ventricular tachycardia on follow-up Holter monitoring and alternative therapy was given. N-acetylprocainamide has antiarrhythmic efficacy in preventing induction of ventricular tachycardia by programmed electrical stimulation in a high risk group of patients. On chronic oral therapy, N-acetylprocainamide appears to be well tolerated with antiarrhythmic efficacy that may be enhanced with further upward dose titration. |
