Know how to read a basic EKG
- P = firing of SA node/ depolarization of atria (.06-.12 sec) (PR interval = .12-.20)
- QRS = depolarization of AV node of ventricles (.04-.12 sec)
- T = repolarization of ventricles (QT interval = .31-.38)U = delayed ventricular repolarization OR hypokalemia
- Times between these waves IMPORTANT!
- R to R interval = pulse rate and should be equal
