Advice for programming devices in non-MRI-conditional patients undergoing magnetic resonance scanning

In pacemaker-dependent patients: asynchronous mode (VOO/DOO) with HF of 80–90/min with high output, RV-only pacing in biventricular devices

In non-pacemaker-dependent patients:

– Resting heart rate >50/min: VVI or DDI 30–40/min

– Resting heart rate <50/min: consider VOO/DOO 80–90/min with high output

– RV-only pacing in CRT patients

Deactivate additional features:

– Rate response mode

– Anti-tachycardia therapies (including anti-tachycardia pacing and shocks)—ICD only

– LV-triggered pacing (ventricular sense response)—biventricular devices only

– Anti-pacemaker-mediated tachycardia pacing (PMT algorithms)

– PVC-triggered pacing response

– PAC-triggered pacing response

– Atrial fibrillation therapies (rate smoothing, overdrive pacing, conducted atrial fibrillation response)

– Hysteresis pacing

– Magnet response (if the option exists)

– Noise response
