• 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:

In light of the fact that reentry involves conduction around a non-conducting area or core, it is easy to understand how the presence of an accessory pathway could lead to reentry; the most common reentry tachycardia with an accessory pathway is called orthodromic AV reentry; in this case, the SA node’s impulse follows the regular pathway ...

Here it receives oxygen and travels back to the heart. This pathway is the pulmonary circuit. The pathway for the systemic circuit includes the entire body as the left side of the heart pumps oxygen-rich blood out to the body's tissue and organs. ... • The intrinsic conduction system of the heart initiates depolarization impulses. • Action ...

Be able to trace the path of normal blood flow through the heart and vascular system starting in the right atrium and returning to the right atrium. Know the pathway of normal electrical conduction through the heart (Fig. 6.5). Understand the basic process of depolarization and repolarization (Chapter 3, p. 72-73).
