Front
Which of the following is correct about ECG?
- A. The P-wave represents atrial depolarization and repolarization.
- B. The Q-T interval approximates the time of ventricular contraction.
- C. The P-R interval includes ventricular repolarization.
- D. The T wave always opposes QRS polarity.
Back
C. The P-R interval includes ventricular repolarization.
- The QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization. The Q-T interval is the time that the ventricle takes to depolarize-repolarize and represents ventricular contraction.
