The high efficiency of the heart pumping system originates in a conductive system, which is linked to the Sinoatrial (S-A) and Atrioventricular (A-V) node. The Sinoatrial node, also known as the natural cardiac pacemaker, is located in the upper part of the right atrium and initiates the contractions of the cardiac muscle by producing special electrical impulses which act as an activation signal for the heart to contract. This occurs in form of a depolarization, which firstly
