Since the early days of pacemaker development electromagnetic interference (EMI) has always been a major concern and challenge to engineers, producers and physicians. The latter has to be aware of adverse effects of certain electric medical devices used near or on a patient carrying a pacemaker. Although highly sophisticated circuits and filters inside modern pacemakers can reject most EMI, concerns still remain and normal pacemaker function can be affected. EMI can be triggered by a variety of medical devices such as electrocautery, magnetic resonance imaging, diathermy, cardioversion and defibrillation, therapeutic radiation and lithotripsy. This article addresses the possible effects of electrocautery and the precautions that should be taken in case such a device has to be used on a patient with a pacemaker.
自起搏器研发初期以来，电磁干扰（EMI）一直是工程师、生产商和医生主要关注和面临的挑战。医生必须意识到在携带起搏器的患者附近或身上使用某些电动医疗设备的不良影响。尽管现代起搏器内部有高度精密的电路和滤波器可以抵御大多数电磁干扰，但担忧依然存在，起搏器的正常功能仍可能受到影响。电磁干扰可由多种医疗设备引发，如电灼术、磁共振成像、透热疗法、心脏复律和除颤、治疗性放射和碎石术。本文阐述了电灼术可能产生的影响以及在必须对有起搏器的患者使用此类设备时应采取的预防措施。
