WebReentry occurs when an action potential reemerges into normal tissue that is no longer refractory. When this happens, a new action potential is generated prematurely (before normal activation) and a circular, repeating pattern of early and rapid activation can develop, which leads to tachycardia.

WebFeb 6, 2024 · Refractoriness in cardiac tissue helps ensure a unidirectional propagation of action potentials through the cardiac syncytium in the same manner that refractoriness ensures the propagation of an action potential in only one direction along an axon. Thus, it is essential for coordinated contraction of cardiac myocytes. References WebApr 12, 2024 · Methods A multicenter, prospective, single group, phase 2 study will be conducted on 81 patients presenting with refractory VF.

WebSome of these more slowly inactivated channels produce late sodium currents. When the channels are in the inactivated (closed) state, inward sodium currents through these channels cease. As the membrane potential repolarizes during phase 3, the inactivated state prevents reactivation of action potentials (i.e., the cell is refractory). is cleopatra aliveWebJan 13, 2024 · Absolutely.
