$Refractory period - Wikipedia$

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 … Web6 de set. de 2024 · During phases 0, 1, 2, and part of phase 3, the cell is refractory to the initiation of new action potentials.This is termed the effective refractory period (ERP). During the ERP, stimulation of the cell does not produce new propagated action potentials. The reason for this is that the fast sodium channels are not fully reactivated and …

Webabsolute refractory period. Note that the absolute refractory period (180 msec) is almost equal in duration to the action potential (200-220 msec). From ~180 msec to 200 msec is called the relative refractory period. During this time period, a second action potential can be fired but the stimulus required is greater than normal.
