The period of time in which the myocardium is insensitive to further stimulation is called the
A)absolute refractory period.
B)hyperpolarization period.
C)AV period.
D)SA period.
E)ectopic focus.

Question

Quizplus · Accepted Answer

The absolute refractory period is the period of time during which the myocardium is insensitive to further stimulation, even if a strong stimulus is applied. During this period, no action potential can be generated regardless of the stimulus strength. This refractory period is important for ensuring proper cardiac contraction and preventing arrhythmias. The other answer choices are not related to the refractory period of the myocardium.
