Physiology of Cardiac Conduction. In an adult with a healthy heart, the heart rate is usually about 72 beats per minute. The excitatory and electrical conduction system of the heart is responsible for the contraction and relaxation of the heart muscle. The sinoatrial node (SA node) is the pacemaker where the electrical impulse is generated.

Based on the location of Caleb’s defect, what part of the conduction system might be at risk for abnormalities? The bundle of His (atrioventricular bundle) and the bundle branches are along the interventricular septum. So, if the defect included a large portion of the septum, all of these areas could be at risk for abnormalities.
