Study Notes
Electrocardiogram (ECG) Components
- The P wave represents atrial depolarization, which is the electrical activity in the atria, causing them to contract.
- The normal duration range for the QRS wave is 0.08-0.12 seconds, representing ventricular depolarization, which is the electrical activity in the ventricles, causing them to contract.
- The T wave represents ventricular repolarization, which is the recovery phase of the ventricles after contraction.
