$What is the Difference Between Absolute and Relative Refractory Period …$

WebApr 12, 2024 · Refractory period. The refractory period is the time after an action potential is generated, during which the excitable cell cannot produce another action potential. There are two subphases of this period, absolute and relative refractoriness. Absolute refractoriness overlaps the depolarization and around 2/3 of repolarization phase. WebThe T wave is the ECG manifestation of ventricular repolarization of the cardiac electrical cycle. The interval from the beginning of the QRS complex to the apex of the T wave is ref2242ed to as the absolute refractory period. The last half of the T wave is ref2242ed to as the relative refractory period, or vulnerable period.
