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.

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.

Heat Stress Prevention Plan
Recovery heart rate. The recovery heart rate can be checked by comparing the pulse rate (i.e., number of beats in 30 seconds x 2) taken at the beginning of the rest period (P1) with the pulse rate taken 3 minutes (P3) after the beginning of the rest period. The two pulse rates can be interpreted using the Heart Rate Recovery Table in this section.

Changes in heart rate influence the amount of blood that is pumped to our tissues. Heart rate can be used to calculate another indicator of heart health called cardiac output. Changes in cardiac output, the amount of blood that is pumped out by the ventricles per minute, often signal disease of the heart.
