Cardiac Electrophysiology: Introduction
The heart contracts in a synchronized manner several billion times in a person’s life. Fortunately, a person does not need to intentionally instruct his or her heart to beat. Rather, the heart can spontaneously generate its own electrical signals, which can then be propagated throughout the cardiac muscle tissue to produce contractions.
