Abstract:
:Thirty-eight patients who had inducible sustained ventricular tachycardia during baseline programmed electrical stimulation underwent electrophysiologic testing after both intravenous and oral administration of procainamide. Each had presented clinically with documented sustained ventricular tachycardia or out of hospital cardiac arrest not associated with acute myocardial infarction. In 23 patients (61%) (Group I) the arrhythmia became noninducible during an intravenous infusion of procainamide. Oral procainamide was subsequently administered and retesting was carried out after dose titration to match plasma concentration at the end of the intravenous study. Among the 23 patients in Group I the mean (+/- SD) plasma procainamide level was 7.2 +/- 2.8 micrograms/ml after intravenous dosing and 7.9 +/- 2.5 micrograms/ml after oral dosing (p = 0.09). In 15 (65%) of the 23 patients, sustained ventricular arrhythmia was inducible on oral therapy with comparable plasma procainamide levels (intravenous = 6.3 +/- 2.1 micrograms/ml, oral = 7.5 +/- 2.1 micrograms/ml). The other eight patients (35%) had concordant responses to repeat testing with comparable intravenous (mean 9.0 +/- 3.3 micrograms/ml) and oral (8.8 +/- 3.1 micrograms/ml) plasma procainamide levels. In the additional 15 patients (Group II) sustained ventricular tachyarrhythmia remained inducible on intravenous procainamide therapy and the patients were retested on oral therapy with similar plasma concentration (p = 0.05). In seven patients (47%) sustained ventricular tachyarrhythmia was noninducible on treatment with oral procainamide (mean plasma level 7.6 +/- 2.7 micrograms/ml) after failure of intravenous procainamide (mean plasma level 10.3 +/- 2.3 micrograms/ml).(ABSTRACT TRUNCATED AT 250 WORDS)
