WebSep 26, 2024 · During the absolute refractory period, another action potential will not start. This is because of the inactivation gate of the voltage-gated Na + channel. Once the Na+ channel is back to its resting conformation, a new action potential could be started during … The refractory period in cardiac physiology is related to the ion currents that, in cardiac cells as in nerve cells, flow into and out of the cell freely. The flow of ions translates into a change in the voltage of the inside of the cell relative to the extracellular space. As in nerve cells, this characteristic change in voltage is referred to as an action potential. Unlike that in nerve cells, the cardiac action …
