Guest guest Posted November 5, 2007 Report Share Posted November 5, 2007 I've got a question for everyone out there... In my animal physiology class, we've been going over the cardiovascular system. I apparently made the mistake of asking what causes U waves on the EKG. First, he poo-poo'ed the idea of a U wave; he only begrudgingly admitted that U waves exist when I showed him old EKGs. When I told him that my AMLS book and the EKG book I showed him described U waves as perkinje repolarization, he flat out said that there's no way this could be--the physics make it impossible. " The Perkinje fibers are way too small to ever show up on an EKG, regardless of what's going on. " I'm a bit on the stupid side, because I couldn't come up with a good rebuttal. So, what are the cause of U waves? And if it is the Perkinje fibers, how can it show up on an EKG?
