Pacemakers are common among Emergency Department patients. Patients may present due to symptoms referable to pacemaker malfunction or symptoms unrelated to the pacemaker, and its presence may modify the investigation and therapeutic approach. It is important for the Emergency Physician to understand the workings of a pacemaker, the problems that may be encountered, the etiologies of the problems, and the assessment of a patient with a pacemaker.
