What happens to Caleb’s systemic cardiac output as a result of his ventricular septal defect (VSD)? Explain your answer. Due to a left-to-right blood shunt, the left ventricular volume falls during systole prior to the opening of the aortic valve. This shunt decreases stroke volume and cardiac output from the left ventricle into the aorta.

E. Cardiac Conduction System . 1. Specialized cardiac muscle tissue conducts impulses throughout the myocardium and comprises the cardiac conduction system. 2. A self-exciting mass of specialized cardiac muscle called the sinoatrial node (S-A node or pacemaker), located on the posterior right atrium, and generates the impulses for the heartbeat. 3.

Activity 4.3.4: Cardiac Output. Introduction. Your heart beats to send blood out through your vessels to your tissues. After each heartbeat, a pressure wave or pulse, passes along an artery as its walls bulge and then relax to withstand the surge of blood.

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.
