title:
Ventricular action potential
text:
In electrocardiography, the ventricular cardiomyocyte membrane potential is about −90 mV at rest, which is close to the potassium reversal potential. When an action potential is generated, the membrane potential rises above this level in five distinct phases. Phase 4: Resting membrane potential remains stable at ≈−90 mV.
Phase 0: Rapid depolarisation, shifting the voltage to positive. Specialised membrane proteins (voltage-gated sodium channels) in the cell membrane selectively allow sodium ions
