Electromagnetic interference produced by medical equipment can interact with implanted cardiac devices such as pacemakers and implantable cardioverter-defibrillators. The most commonly observed interaction is in the operating room with electrosurgery. The risk of interactions can often be mitigated by close communication between the cardiac-device specialist and the anesthesiology/surgical team to develop a patient-specific strategy that accounts for factors such as type of device, type of surgery, and whether the patient is pacemaker dependent. Although magnetic resonance imaging should generally not be used in patients with implanted cardiac devices, several published guidelines provide strategies and recommendations for managing risks if magnetic resonance imaging is required with no suitable diagnostic alternatives. Other common sources of electromagnetic interference in the medical environment are ionizing radiation and left ventricular assist devices.
医疗设备产生的电磁干扰可能会与植入式心脏设备(如起搏器和植入式心脏除颤器)相互作用。最常见的相互作用发生在手术室中,涉及电外科手术。通过心脏设备专家与麻醉/手术团队之间的密切沟通,可以制定出针对特定患者的策略,考虑设备类型、手术类型以及患者是否依赖起搏器等因素,从而降低相互作用的风险。尽管通常不建议在植入心脏设备的患者中使用磁共振成像,但有几项已发表的指南提供了在没有合适诊断替代方法时需要进行磁共振成像的情况下,管理风险的策略和建议。医疗环境中其他常见的电磁干扰源还有电离辐射和左心室辅助设备。
