1
Q
SAN depolarisation
A
2
Q
atrial depolarisation
A
3
Q
delay at AV node
A
4
Q
spread of depolarisation from atrium to ventricle
A
5
Q
Depolarisation of the interventricular septum
A
6
Q
Depolarisation of apex and free ventricular walls
A
- large because large muscle mass
- more electrical activity (if left ventricle is hypertrophies- the R wave will be correspondingly taller)
7
Q
Last part of depolarisation
- spreads up the ventricles
A
8
Q
Ventricular repolarisation
A
- Upwards because wave of repolarisation moving away from electrode
- In comparison when depolarisation moves away from lead produced negative deflection
