the most common location of heart block. The AV node is profoundly influenced by autonomic tone; blood supply is from the right coronary artery in 90% of cases, the left circumflex in the remainder. C. His-Purkinje System and Ventricles The rapid spread of impulses through the ventricles is mediated by cells of the His-Purkinje system (HPS).
There is an electrical system inside your heart that controls the rate (speed) and rhythm of your heart. A normal heart rhythm is called normal sinus rhythm (NSR). When there is a problem with your heart rhythm or rate, it is called arrhythmia. The heart’s electrical system It starts with an electrical signal in the right atrium, at the SA Node

It is important to understand how cardiac physiology is intertwined with other organ systems and how pathophysiology relates back to simple gross physiology. Cardiac physiology is one of the most important pieces of medical knowledge in healthcare. The cardiovascular system is constantly adapting to maintain homeostasis in the body, specifically to maintain oxygen perfusion of tissues. The
Heart: This is what pumps blood around the body. Because the heart is a muscle, it . also needs oxygen, so it has its own circulatory system known as the . coronary circu-lation, which takes blood to and from the heart.

The heart is a muscular structure that is situated in the front of the chest. It pumps blood all through the body in a process called circulation. Apart from the heart, the blood vessels and blood as a unit constitute the cardiovascular system. Table of Contents Introduction Position Functions of the Human Heart Types of Circulation The heart is subdivided by septa into right and left halves, and a constriction subdivides each half of the organ into two cavities, the upper cavity being called the atrium, the lower the ventricle. The heart, therefore, consists of four chambers: right atrium left atrium right ventricle left ventricle [5].
