At 19 cm CVRL, it was composed of Purkinje fibers, thin layer of myocardium, and endocardium.
The capillary lymphatic system has been demonstrated by various techniques to be present in the conduction tissue of mammalian hearts: in the sinoatrial node of man, dog, and rabbit [15, 16, 27, 34, 35], in the atrioventricular node of man, dog, and rabbit [16, 34-36], in the His bundle of man and rabbit, in the right bundle branch of dog [37], in the left bundle branch of sheep, and in the Purkinje fibers of the moderator band in sheep [38].
(3) Birds have a cardiac conduction system, similar to that of mammals, and consists of a sinoatrial node, an atrioventricular node, and Purkinje fibers. The sinoatrial node is the primary pacemaker, which conducts the electrical impulse to the atrioventricular node and by way of the atrioventricular bundle to the ventricles.
Drugs, including antiarrhythmic drugs that prolong repolarization, do not uniformly prolong repolarization in all three layers of myocardium and Purkinje fibers, resulting in heterogeneity of repolarization.
