title: Electrophysiologic effects of disopyramide in Chagas' disease with bundle branch block.
abstract: We report the acute electrophysiologic effects of disopyramide in 16 asymptomatic chagasic individuals with right bundle branch block. The drug increased the heart rate, prolonged the H-V interval and enhanced the conductivity through the A-V node.
