Pacemaker cells and Purkinje fibres in the conduction system are specialized cardiomyocytes that generate and conduct electrical impulses. The sinoatrial node (SAN), which is composed of a group of pacemaker cells, resides in the right atrium generating impulses to initiate heart contraction. The atrioventricular node (AVN) is located between the atria and ventricles, and it conducts an electrical impulse from the atria to the ventricles. Mei Xin,
Impulses pass from the autorhythmic cardiac cells in the sinoatrial node through atrial myocytes to the atrioventricular node, down the atrioventricular bundle (bundle of His) to the right and left bundle branches and on to the Purkinje fibers.he right side of the heart is the pulmonary circuit pump. Pumps blood through the lungs, where CO 2 is unloaded and O 2 is picked up. The left side of the heart is the systemic circuit pump. Pumps blood to the tissues, delivering O 2 and nutrients and picking up CO 2 and wastes.
