Which of the following waves of an ECG pattern is/are correctly described?
A)P wave-depolarization of atria
B)QRS complex-repolarization of ventricles
C)T wave-depolarization of ventricles
D)QRST complex-depolarization of ventricles

Question

Quizplus · Accepted Answer

The P wave represents the depolarization (contraction) of the atria, causing them to pump blood into the ventricles.

Answer: None 
 None of the options have correctly described all the waves. The QRS complex represents the depolarization (contraction) of the ventricles, while the T wave represents the repolarization (relaxation) of the ventricles.
