... The S-A (sinoatrial) node is a small mass of specialized muscle tissue just beneath the epicardium. The fibers are self-exciting so they initiate impulses that spread to the myocardium and stimulate the muscle fibers to contract. The S-A node initiates one impulse seventy to eighty times per minute. ...
