1 C Depolarization of atrial nerves The P wave indicate atrial depolarizartion P wave occur when SA node sino atrial node creates an action potential that depolarizes atria Normal PR interval is 06 12 second Option D is incorrect because ventricular depolarization is marked by QRS complex option A is incorrect because ventricular repolarization is marked by T wave Option B is    See Answer
