In patients with implanted pacemaker/cardioverter defibrillator (ICD), the use of electrocautery can lead to serious pacemaker dysfunction. The ultrasonically activated scalpel, however, which has been introduced mainly for the use in laparoscopic surgery, could potentially avoid the outlined problem, since no electrical current flows while in use. This hypothesis was tested in a pacemaker patient undergoing laparoscopic cholecystectomy. During the procedure, no abnormal rhythms or ECG interferences were detected while working in close vicinity to the device. Thus, the ultrasonically activated scalpel provides adequate hemostasis and does not bear the risk of pacemaker dysfunction.
在植入起搏器/心脏复律除颤器（ICD）的患者中，使用电灼术可能会导致严重的起搏器功能障碍。然而，主要用于腹腔镜手术的超声刀有可能避免上述问题，因为在使用时无电流通过。在一名接受腹腔镜胆囊切除术的起搏器患者身上对这一假设进行了验证。在手术过程中，在靠近该装置的位置操作时未检测到异常节律或心电图干扰。因此，超声刀能提供足够的止血效果，且不存在起搏器功能障碍的风险。
