Choose the correct term for the description given about the heart.

T wave: corresponds with end of ventricular contraction (systole) and beginning of ventricular relaxation

ECG: an electrical recording of the heart made of waveforms (P wave, QRS complex, T wave)

P wave: corresponds with atrial contraction and atrial depolarization

SA Node: the part of the conduction system that initiates electrical impulses to the myocardium and is termed the "pacemaker" of the heart

conduction system: this electrical stimulus to the heart muscle is achieved through the _________ through the aorta

QRS complex: corresponds with ventricular contraction (systole) and ventricular depolarization

depolarize: process of reversing the charge across a cell membrane
