Absolute refractory period in cardiac muscle

Hi there,
The cardiac cell is unable to initiate another action potential for some duration of time (which is slightly shorter than the "true" action potential duration). This period of time is referred to as the refractory period, which is 250ms in duration and helps to protect the heart.

hola there

This is the time during which another stimulus given to the neuron (no matter how strong) will not lead to a second action potential. Thus, because Na+channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials. Theabsolute refractory period takes about 1-2 ms
