WebApr 10, 2024 · The ventricular action potential is generally split into 5 phases ( phases 0-4 ). Rather confusingly, phase 4 is the baseline that the membrane potential begins and ends at. Like any action potential, each phase is driven by the opening and closing of a variety of specific ion channels. This is because opening an ion channel will push the ...
