Hey guys had a quick concept that i got stuck on. Kaplan notes say that hypercalcemia shortens the QT segment. And then they go on to say that QT segment corresponds to the plateau phase of the action potential. I was confused as to how this would happen. I was thinking that since in the plateau phase the calcium channels are open and calcium moves into the cell. So in hypercalcemia more calcium would move in hence prolonging the QT segment rather than shortening it. I looked at it from this angle but maybe there is a different way to look at it. Would appreciate the help. thanks.
