C wave on ekg
WebIn C, the action potential has reached the midpoint, at this point we will get the maximum deflection on the EKG. In D, only one cell remains at rest and the tracing is returning toward the isoelectric point. In E, all of the cells are depolarized, all negative on the outside and the EKG has returned to the isoelectric point.
