title: [Influence of electrical stimulation of the heart on coronary circulation (author's transl)].
abstract: Coronary perfusion was measured in anaesthetized dogs under sinus rhythm, after creation of an acute AV-block, and during pacing of the heart at frequencies of 60 to 150 min-1. With increased heart rate coronary perfusion was enhanced. The close relation between heart rate and coronary perfusion is not influenced by artificial stimulation. The improvement in coronary circulation under pacing after creating of the A-Vblock is due exclusively to the rise in heart rate.
