Study Notes
Cardiac Electrical Activity
- P Wave: Represents the depolarization of the atria, initiating atrial contraction.
- PR Interval: Measured from the start of the P wave to the start of the Q wave, indicating the time taken for impulses to travel from the atria to the ventricles.
- T Wave: Represents the repolarization of the ventricles, allowing them to reset after contraction.
- QRS Complex: Represents the depolarization of the ventricles, leading to ventricular contraction.
- ST Segment: Measured from the end of the S wave to the start of the T wave, reflecting the period when the ventricles are depolarized.
- QT Interval: Measured from the start of the Q wave to the end of the S wave, indicating the total duration of ventricular depolarization and repolarization.
