摘要

A 58-year-old man with ischemic cardiomyopathy and an ejection fraction of 30% received an implantable cardioverter-defibrillator (ICD). The patient worked as a machinist and presented to the emergency room after sustaining sharp penetrating as well as blunt trauma to his chest from a fractured grinding wheel. On presentation, he had a 1-cm vertical laceration over his left chest at the medial edge of the ICD pocket, partially exposing the device, A limited device interrogation showed normal telemetry, battery voltage of 3.21V, R-wave sensing of 19.3 mV, pacing impedance of 504 ohms, and defibrillator impedances of 54 ohms (right ventricular coil) and 72 ohms (superior vena cava coil). Evaluation of the capacitor charge time was not performed in the emergency room. A chest roentgenogram did not show evidence for pneumothorax and a transthoracic echocardiogram revealed no evidence of cardiac contusion or pericardial effusion. The emergency ward physician then irrigated the pocket and sutured the laceration.
