Atrioventricular block response to exercise and intraventricular conduction at rest.


Sixty patients with atrioventricular block were exercised and monitored by a radioelectrocardiograph. Cases with a bundle-branch block QRS pattern at rest presented an improvement of atrioventricular conduction on exercise in I2@5 per cent, no change in 43-8 per cent, and an impairment in 43 8 per cent of cases. Corresponding figures in cases with no… (More)
