Describe the following terms:
P wave
QRS complex
T wave
P-Q interval
S-T segment
Q-T interval - answer • P wave - atrial depolarization (0.1s later atria
contract)
• QRS complex - Ventricular depolarization (hides atrial repolarization)
• T wave - Ventricular repolarization
• P-Q (PR) interval - beginning of P to begin QRS
o Indicates the conduction time from atrial depolarization to
ventricular depolarization.
• S-T segment - end of S to begin T
