3. Once the impulse reaches the bundle of His and penetrates the AV valves, the impulse bifurcates into the right and left bundle branches and continues until it reaches the Purkinje fibers.
4. A slowing of the conduction because of calcium ions occurs when the impulse is moving through the atrioventricular node.
5. A flat line after the P wave on the ECG rhythm occurs when the impulse travels through the atrioventricular node.
