Feedback:
The fibers of the cardiac muscle, or myocardium, form two intertwining networks called the atrial and ventricular syncytia. A myocardial infarction impacts this layer, which results in reduced pumping ability. The endocardium is the inner lining of the heart that comes in contact with the blood. The pericardium is the sac around the heart. The epicardium is the outermost layer of the heart.
