The condition is most often caused by a severe heart attack, but not everyone who has a heart attack has cardiogenic shock. Cardiogenic shock is rare. It's often deadly if not treated immediately.
WebIn addition, the refractory period acts as a protective mechanism by preventing multiple, compounded action potentials from occurring (i.e., it limits the frequency of depolarization and heart rate). Therefore refractoriness is a determinant of susceptibility to arrhythmias. In general, shorter refractoriness facilitates reentry and arrhythmias. 9 WebHeart Muscle Refractory Period.
