<P> When the visceral layer of serous pericardium comes into contact with heart ( not the great vessels ) it is known as the epicardium . The epicardium is the layer immediately outside of the heart muscle proper ( the myocardium ) . The epicardium is largely made of connective tissue and functions as a protective layer . During ventricular contraction , the wave of depolarization moves from the endocardial to the epicardial surface . </P>
