摘要
P>We describe the case of an accidental intraoperative ventricular fibrillation that could not be interrupted by a 35-J shock fired by an implantable cardioverter defibrillator (ICD). We believe that the iatrogenic pneumothorax induced by thoracotomy during the epicardial lead implant temporarily changed the intrathoracic impedance, causing an increase in defibrillation threshold. This possible change in impedance with resulting ineffective interruption of arrhythmia should be taken in consideration when a thoracotomy is planned in a patient bearing an ICD. (J Card Surg 2011;26:338-339).
