1. What is depolarization in EKG terms? Depolarization is the process of the heart
muscle contracting.
2. What is repolarization in EKG terms? Repolarization is the process of the heart
muscle relaxing and refilling with blood.
3. What does the P-wave represent? The P-wave represents atrial depolarization.
4. What does the PR interval indicate? The PR interval is the time between atrial de-
polarization and ventricular depolarization.
5. What does the QRS interval represent? The QRS interval represents ventricular depo-
larization.
6. What does the T-wave indicate? The T-wave indicates ventricular repolariza-
tion.

sinus rhythm?
8. What defines tachycardia? Tachycardia is a heart rate greater than 100
bpm.
9. What defines bradycardia? Bradycardia is a heart rate less than 60 bpm.
