The refractory period is an interval following a paced or sensed event in the chamber containing the pacing or sensing lead, during which the inhibited (SSI) or triggered (SST) pacemaker is not reset. In a VVI pacemaker, the first part of the refractory period is a programmable, absolutely refractory blanking period.

Younger men may need only a few minutes of recovery time, but older men usually have a longer refractory period, sometimes between 12 to 24 hours. For some men, the refractory period can last a few days 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. Once inactivated, the Na + channel cannot respond to another stimulus until the gates are reset. The absolute refractory period of a human muscle fibre is typically between 2.2 and 4.6 ms. The refractory period causes 3 things to occur: The brain will be able to perceive nerve impulses as separated events since there is a time lag between them. The number of generated impulses or repetitive firing rate of a neuron will be limited in a The refractory period varies from one man to another, meaning it might take anywhere from a few minutes to several hours for you to recover after sex.

This time interval is when a new nerve impulse (action potential) cannot be propagated regardless of the presence of a strong stimulus because the sodium channels are inactivated and have not yet recovered from the previous action potential.

The refractory period sets a limit on the frequency at which action potentials can be conducted along single nerve fibres. In mammals, the absolute refractory period is about 1 millisecond and the maximum firing frequency is around 1000 impulses per second (although it is rare for fibres to fire naturally at rates above a few hundred per second). refractory period the period of inexcitability, that normally lasts about three milliseconds, during which the AXON recovers after it has transmitted an impulse. During the refractory period it is impossible for the axon to transmit another impulse, because the membrane is being repolarized by ionic movements at this time. The refractory period sets a limit on the frequency at which action potentials can be conducted along single nerve fibres. In mammals, the absolute refractory period is about 1 millisecond and the maximum firing frequency is around 1000 impulses per second (although it is rare for fibres to fire naturally at rates above a few hundred per second). Refractory Period.

Refractory period is a period immediately following a stimulus during which further stimulation has no effect.
