Electrophysiologic effects of disopyramide in Chagas' disease with bundle branch block.
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.
