*[[McGill Case 161|A pacemaker that required inversion of the programming head for programming. The pacemaker could not be programmed in the usual manner in the pacemaker clinic. The pacemaker was implanted correctly with the conducting window toward the skin, but was a left-sided model which differed from the previous x-ray outline of the right-sided model. Having to invert the programming head suggests a problem with the programming head, inverted implantation of the pacemaker, or because the pacemaker electronics are functioning as a contra-lateral pacemaker.]]
