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].

The conducting system consists of the sinoatrial node, the atrioventricular node and bundles, and highly complex network of fine bundles and tracts [16].
The right vagus nerve innervates the sinoatrial node, and parasympathetic hyperstimulation predisposes those affected to bradyarrhythmias; the left vagus nerve when hyperstimulated predisposes the heart to atrioventricular (AV) blocks, but these facts do not affect our results because we recorded average heart rate variability for 5 minutes before and after gagging.
Her past medical history included hypertension, stage 4 chronic kidney disease, bio-prosthetic aortic valve replacement and a permanent cardiac pacemaker for sinoatrial node disease.
In healthy subjects the sinoatrial node located at the posterior wall of the right atrium initiates each beat of the heart.
This occurs when the activity of the heart's pacemaker, the sinoatrial node, is impaired.
Much like the sinoatrial node of the heart, functional regulation of ICCs is achieved by autonomic innervations from the central nervous system.
