Quizplus · Accepted Answer

A premature ventricular contraction (PVC) is a single, ectopic complex that occurs earlier than the next expected complex and arises from the irritable site in the ventricles. A premature atrial contraction (PAC) is a single, ectopic complex that occurs earlier than the next expected complex and arises from the irritable site in the atria. A premature junctional contraction (PJC) is a single, ectopic complex that occurs earlier than the next expected complex and arises from the irritable site in the junction between the atria and ventricles. There is no such thing as a PUC in cardiac terminology.
