Match the normal findings of an ECG with their definitions.
-Represents atrial depolarization
A)P wave
B)QRS complex
C)T wave
D)Q-T interval
E)ST segment

Question

Quizplus · Accepted Answer

The P wave represents atrial depolarization, or the contraction of the atria.

Answer: B 
 The QRS complex represents ventricular depolarization, or the contraction of the ventricles.

Answer: C 
 The T wave represents ventricular repolarization, or the relaxation of the ventricles.

Answer: D 
 The Q-T interval represents the time between ventricular depolarization and repolarization.

Answer: E 
 The ST segment represents the interval between ventricular depolarization and repolarization, and is used to diagnose myocardial ischemia or injury.
