This case involves an elderly female patient who was given an EKG after experiencing persistent chest pain for several weeks. A heart block was diagnosed and a pacemaker was implanted. While the patient was recovering from the surgery, she developed severe pain in her chest. The patient went to the hospital and it was determined that the lead detached and perforated the cardiac tissue. The pacemaker was removed then replaced. Following the replacement procedure, an infection was suspected and a pericardial window was ordered. The procedure revealed signs of infection around the lead and a subsequent culture revealed an anaerobic bacterial infection. In spite of antibiotic treatment, the patient’s cardiac function continued to worsen.
