Electrical conduction system of the heart - Wikipedia
Figure 2. Components of the human heart involved in conduction. The cardiac cycle involves a sequential contraction of the atria and the ventricles. The combined electrical activity of the different myocardial cells produces electrical currents that spread through the body fluids.

The electrical impulses generated by the heart’s conduction system begin in the . sinoatrial node (SA node), which is located in the upper wall of right atrium (Figure 1) near the entrance of the superior vena cava. Since the heart’s electrical activity begins with the SA node, it is known as the pacemaker of the …
HEART - Nassau Community College
The heart’s electrical conduction system controls heart rate and helps to keep the atria and ventricles working together. The mechanical pumping action of the heart can occur only in response to an electrical stimulus. The electrical conduction system consists of the sinoatrial (SA) node, the atrioventricular (AV) node, the bundle of His, the ...

• The intrinsic conduction system of the heart initiates depolarization impulses. • Action potentials spread throughout the heart, causing coordinated heart contraction. • An ECG wave tracing records the electrical activity of the heart. ** Now is a good time to go to quiz questions 3 and 4:

Understand the relationship of the normal electrical conduction through the heart and the ECG (Fig. 6.8). Know the electrical events in the heart that produce the P-wave, QRS-wave and T-wave of the ECG. Know the intrinsic rate of impulse generation from the SA node and why the resting HR is lower than the intrinsic rate of the SA node.

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.
