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)

Q

Ventricular repolarisation

A
  • Upwards because wave of repolarisation moving away from electrode
  • In comparison when depolarisation moves away from lead produced negative deflection
