There is a growing population of patients with implanted electronic cardiac devices and a concomitant increase in the use of magnetic resonance (MR). There are theoretical safety risks posed to such devices by MR. However, there are now considerable laboratory data and clinical experience demonstrating safety in this setting, assuming appropriate device selection and patient monitoring. Herein, we review these data and our safety protocol and the new generation of devices that have been prospectively designed and tested to be safe for MR scanning, assuming certain conditions are met (i.e., devices that are MR-conditional). We also argue that the available data do not support a complete transition to implantation of MR-conditional devices.
越来越多的患者植入了电子心脏设备，同时磁共振（MR）的使用也在增加。MR 对这些设备存在理论上的安全风险。然而，现在有大量的实验室数据和临床经验证明了在适当的设备选择和患者监测的情况下，这种设置是安全的。在此，我们回顾这些数据以及我们的安全协议和新一代设备，这些设备是为满足一定条件（即符合磁共振条件的设备）的磁共振扫描而设计和测试的。我们还认为，现有数据不支持完全过渡到植入符合磁共振条件的设备。
