PVCs may be unifocal or multifocal in origin. PVCs will not lead to ventricular tachycardia. PVCs only originate from one site in the ventricles. PVCs may be unifocal or multifocal in origin. A regular rhythm at a rate of 40-60 beats per minute, with narrow QRS complexes, and no visible P waves, is consistent with the presence of: atrial fibrillation. sinus bradycardia. junctional rhythm. idioventricular rhythm. junctional rhythm.
