The history of the heart conduction system starts from Harvey, who first observed that right atrium is the origin of cardiac contraction. The subsequent series of discoveries of the origin and conduction of the electrical cardiac impulse followed, oddly enough, a reverse route, from peripheral ...

The heart has a complex electrical system which regulates the contraction and relaxation of its muscular wall. This enables the heart to function by receiving blood during relaxation and pumping it out with force to the lungs and other parts of the body. The rhythm of the heart beat is contro...
