1. Depolarization during contractile myocardium and Purkinje fiber action potentials is due to the influx of 2. Repolarization of the action potential in contractile myocardium and Purkinje fibers is due to the outflow of 3. The plateau phase during the action potential is due to the influx of during repolarization. 4. The is the primary pacemaker of the heart. 5. The is the electrical connection between the atria and ventricles. 6. The is a secondary pacemaker of the heart. 7. The and rapidly spread depolarization from the atrioventricular node to the thick ventricular myocardium. 8. The two are found along the interventricular septum. 9. The directly depolarize the contractile myocardium of the
