Artificial cardiac pacing: 2. follow-up and complications.

Following insertion or implantation of an artificial cardiac pacemaker, both physician and patient are involved in aftercare to monitor the patient's cardiac status, the condition of the implantation site, and the function of the pacemaker. Among the complications that may occur are pacemaker malfunction and perforation of the ventricles. The physician and patient must also be alert to the possibility of electrical interference and to the physiologic factors that can modify pacemaker function.
