TOPIC SUMMARY
1. Measures cardiac muscle depolarization, not the signal transmitted through the conduction system.
5. PR interval: interval from onset of atrial to ventricular depolarisation.
6. QT interval: duration of ventricular depolarisation & repolarisation.
7. QRS duration: duration of ventricular depolarisation.
8. RR interval: duration of ventricular cycle.
9. PP interval: duration of atrial cycle.
COMPONENTS
