为了研究全球移动的通信系统（GSM）移动的电话的高频电磁场（EMF）对心律管理设备（CRM）和程控仪之间通信的干扰以及如何避免干扰，进行了一项体内和体外联合测试。在体内测试过程中，GSM移动的电话干扰了33/65例受试者（50.8%）的CRM程控仪通信。心室感知丧失在本研究中具有代表性。在临床症状方面，只有4名受试者（0.6%）在测试期间感到头晕。CRM-程控仪通信在移动的电话通信终止后恢复。在体外测试期间，在20个CRM中的18个（90%）的重复测试中，高频（700- 950 MHz）EMF的电磁干扰可重复发生。在每次干扰期间，程控仪上的起搏脉冲信号会突然消失，而示波器上的同步信号正常。模拟分析表明，射频发射器械对CRM程控仪通信的干扰可能归因于材料、激励源距离和植入深度等因素。结果表明，不应限制植入CRM的患者使用GSM移动的电话;但是，在程控过程中，CRM应远离GSM移动的电话的高频EMF。生物电磁学36：367-376，2015.

To investigate interference, and how to avoid it, by high-frequency electromagnetic fields (EMFs) of Global System for Mobile Communications (GSM) mobile phone with communication between cardiac rhythm management devices (CRMs) and programmers, a combined in vivo and in vitro testing was conducted. During in vivo testing, GSM mobile phones interfered with CRM-programmer communication in 33 of 65 subjects tested (50.8%). Losing ventricle sensing was representative in this study. In terms of clinical symptoms, only 4 subjects (0.6%) felt dizzy during testing. CRM-programmer communication recovered upon termination of mobile phone communication. During in vitro testing, electromagnetic interference by high-frequency (700-950MHz) EMFs reproducibly occurred in duplicate testing in 18 of 20 CRMs (90%). During each interference, the pacing pulse signal on the programmer would suddenly disappear while the synchronous signal was normal on the amplifier-oscilloscope. Simulation analysis showed that interference by radiofrequency emitting devices with CRM-programmer communication may be attributed to factors including materials, excitation source distance, and implant depth. Results suggested that patients implanted with CRMs should not be restricted from using GSM mobile phones; however, CRMs should be kept away from high-frequency EMFs of GSM mobile phone during programming.
