Electrical Diagram Of The Heart. Like all muscle the heart needs a source of energy and oxygen to function. The first part of the wave called the p wave is a small increase in voltage of about 0 1 mv that corresponds to the depolarization of the atria during atrial systole.
The heart s electrical system. Electrical conduction system of the heart. In the simplest terms the heart is a pump made up of muscle tissue.

The cardiac conduction system is the electrical pathway of the heart that includes in order the sa node av node bundle of his bundle branches and purkinje fibers. The components of the heart s electrical system including the sinus node sn and atrioventricular node av node are illustrated here. The heart s electrical system. The atria upper chambers and the ventricles lower chambers.
