What causes the relative refractory period
The relative refractory period is the interval of time during which a second action potential can be initiated but initiation will require a greater stimulus than before.Refractory periods are caused by the inactivation gate of the Na channel.

Refractory Period. Refractory periods are an essential component of all pacing modes that involve sensing of intrinsic cardiac events. 5 6 In single-chamber modes with sensing there is a ventricular refractory period (VRP) or an atrial refractory period (ARP) depending on the relevant chamber. It is initiated by paced or sensed events after

The refractory period is very long to prevent the possibility of tetany a condition in which muscle remains involuntarily contracted.

In physiology a refractory period is a period of time during which an organ or cell is incapable of repeating a particular action or (more precisely) the amount of time it takes for an excitable membrane to be ready for a second stimulus once it returns to its resting state following an excitation. It most commonly refers to electrically excitable muscle cells or neurons.
