[Influence of electrical stimulation of the heart on coronary circulation (author's transl)]. 1977

F Rényi-Vàmos

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.

D010138	Pacemaker, Artificial	A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external).

D003326	Coronary Circulation	The circulation of blood through the CORONARY VESSELS of the HEART.	Circulation, Coronary
D004285	Dogs	The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)	Canis familiaris,Dog
D006327	Heart Block	Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
