根因分析
AI未能识别该起搏器型号（如美敦力Advisa SR）非MRI兼容，且导线（如CapSureFix Novus）未获MRI批准，导致强制MRI前安全检查表被危险地覆盖。
English
AI failed to recognize that the pacemaker model (e.g., Medtronic Advisa SR) is not MRI-conditional and the leads (e.g., CapSureFix Novus) are not approved for MRI, leading to a dangerous override of the mandatory pre-MRI safety checklist.

-
Always perform a full device interrogation (e.g., using Medtronic CareLink or Abbott Merlin) before MRI. If the device is non-MRI-conditional, cancel the MRI and schedule an alternative imaging (e.g., CT with cardiac gating). Document in the EHR: 'MRI contraindicated due to non-MRI-conditional pacemaker.'
-
Implement a hard stop in the MRI scheduling system: require the patient's pacemaker model and lead model to be entered and validated against the MRI-conditional database (e.g., www.mrisafety.com) before the order can proceed.
-
If emergency MRI is absolutely necessary (e.g., suspected spinal abscess), obtain cardiology and radiology co-signature, reprogram the device to asynchronous mode (VOO/DOO) before scan, and monitor ECG during the scan with a resuscitation team on standby.
无效尝试
常见但无效的做法:
-
80% 失败
Assuming all modern pacemakers are MRI-conditional and bypassing the device interrogation step.
-
70% 失败
Relying on the patient's verbal confirmation of 'MRI-safe' without checking the device ID card or manufacturer database.
-
90% 失败
Using a generic 'pacemaker present' override code (e.g., 'MRI-OVR-001') without radiology or cardiology approval.
