Multiple conduction defects with markedly prolonged ventricular depolarization in cardiomyopathy.
Electrophysiologic investigation of a diffuse and bizarre conduction abnormality in a patient with cardiomyopathy revealed profound slowing of the impulse in the right ventricular outflow region. The resultant 220 msec QRS duration is the longest reported in right bundle branch block.
