Question

Quizplus · Accepted Answer

A Premature Atrial Complex (PAC) is a single ectopic beat that originates from an ectopic focus in the atria, causing an early depolarization of the atria before the next expected sinus beat. It can be identified on an electrocardiogram (ECG) as a P-wave that appears different from the sinus P-wave and occurs earlier than expected.
