Question

Quizplus · Accepted Answer

A compensatory pause is a pause that follows an ectopic beat, but the SA node is unaffected and the rhythm of the heart is uninterrupted. The pause is called compensatory because it compensates for the extra beat that occurred with the ectopic beat. Atrial pause refers to a pause caused by the absence of an atrial beat, noncompensatory pause is a pause that occurs after an ectopic beat in which the SA node is affected, and junctional pause refers to a pause caused by a delay in the electrical signal through the AV node.
