is ventricular depolarisation same as depolarisation during nerve impulse conduction?
Depolarisation of nerve (here Purkinje fibres) causes Action Potential (bcoz of opening of voltage gated Na channels) which causes opening of Ca++ channels in membrane of heart muscle- results in ventricular contraction
So ventricular depolarisation is actually action potential in heart muscle of ventricles
So both terms are related
Ventricular depolarisation is a consequence of nerve impulse(depolarisation of nerve here Purkinje fibres )
