Why the study?
Do propranolol, practolol, and dextro-propranolol alter atrioventricular conduction as measured by His bundle potentials in patients?

This study evaluates the electrophysiological effects of different beta-blockers on atrioventricular conduction using His bundle recordings.
Changes in atrioventricular conduction produced by propranolol, practolol, and dextro- propranolol were studied in Io patients using the technique of recording His bundle potentials.
