Abstract

SummaryBy use of a pump-oxygenator and cardiopulmonary bypass, bipolar electro-grams have been recorded under direct vision from the bundle of His, the right and left bundle branches and peripheral Purkinje system of dog hearts. Conduction velocity from the bundle of His to bundle branches is 1.0-1.5 m/sec, while in the false tendons this value is 3-4 m/sec at 36°C.
