During one year, the heart initiates approximately 32 million heartbeats to pump blood around the body, beating a total of 60-80 times per minute at a normal pace. It is a highly efficient organ and constantly works to keep our blood circulation going and ourselves alive.
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
