Excitability - Answer- the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization - Answer- occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity - Answer- the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex: the wave of depolarizat...

Which statement is correct regarding premature ventricular complexes (PVCs)? PVCs originate from the atrium. 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. juncti...
