Study Notes
ECG Waves
- The normal duration range of the QRS wave in an ECG is 0.08-0.12 seconds.
- The P wave represents the atrial depolarization, which is the electrical activity that occurs when the atria (upper chambers) of the heart contract.
- The T wave represents the ventricular repolarization, which is the period when the ventricles (lower chambers) of the heart recover and prepare for the next heartbeat.
