title: Sudden death under successful medical management of sick sinus syndrome after cardiac pacing discontinuation.
abstract: Bacterial infection is a serious complication of permanent pacemaker implantation. A 52-year-old woman with sick sinus syndrome and vasospastic angina developed pacemaker infection 4 years after implantation, with methicillin-resistant Staphylococcus aureus detected in arterial blood cultures. We treated the septicemia with antibiotics and removed the infected pacemaker. We treated sick sinus syndrome with intravenous nitroglycerin followed by oral maintenance isosorbide mononitrate. After cardiac pacing was discontinued following removal of the infected permanent pacemaker, the patient remained well, until her sudden death 3.5 years later. Although the precise cause of death was not clear, we suspected sick sinus syndrome or vasospastic angina, and now consider the outcome may have been more favorable if we had reimplanted a permanent pacemaker before she died.
