Description

Cardiovascular System: Intrinsic Conduction System of the Heart 1. List the functions for the following parts of the intrinsic conduction system: a. SA node ____________________________ b. AV node ____________________________ c. AV bundle (bundle of His) ____________________________ d. Bundle branches __________________________ e. Purkinje fibers ____________________________ 2. The action potentials spread from the autorhythmic cells of the intrinsic conduction system (electrical event) to the ______________ cells. The resulting mechanical events cause a heartbeat. 3. A tracing of the electrical activity of the heart is called a/an ________________. 4. What do the following wave forms reflect? a. P wave ____________________________ b. QRS complex ____________________________ c. T wave ____________________________ 5. In a normal ECG wave tracing, atrial repolarization is hidden by the ___________________. 6. Electrical events lead to mechanical events. For example, the P wave represents ____________ depolarization, which leads to atrial _____________....
