The acute efficacy and electrophysiologic effects of intravenous flecainide acetate (1.5 mg/kg) on 10 patients with concealed AV pathway with supraventricular tachycardia (SVT) by esophageal programmed electrical stimulation were evaluated. The results showed that: (1) the drug has marked depressing effects on the retrograde accessory pathway conduction and minimal effects on the antegrade AV nodal conduction; (2) there were no effects on the patients with normal sinus node function; (3) the drug has little side effects during the studies; (4) flecainide terminated induced SVT in 9 of 10 cases (90%), and prevented induced SVT in 7 of 9 cases (78%).
