Disclaimer...i have not done cardiology yet
Systole from QRS to end of the T wave has rapid intra/extra cellular changes in electrolyte balances and takes in phases 0, 1,2 and 3
Diastole is during the resting state where the electrolytes are at equilibrium (resting membrane potential) and there is complete rest i.e no mechanical, electrical or electrolyte movement and constitutes phase 4
One has electrolyte movement, the other does not...at least thats what i get out of the Dubin book :?
Its most likely wrong but i thought id have a crack anyway 8)
