## TL;DR

The paper discusses how a Medtronic MRI-conditional device can be safely used with a non-MRI-conditional lead by adjusting MRI mode settings through intermediate steps.

## Contribution

The study demonstrates a novel stepwise approach to safely activate MRI mode in a specific device configuration.

## Key findings

- Switching directly to MRI mode from VDD or VVI mode was not possible.
- Switching to DDD mode first allowed subsequent activation of MRI mode.
- This method enables safe MRI imaging with non-MRI-conditional leads.

## Abstract

A Medtronic MRI‐conditional device connected to an MRI‐non‐conditional VDD lead, which required specific adjustments in MRI mode settings to enable safe imaging. Although switching to MRI mode from VDD mode or VVI mode was not possible, it became possible after switching to DDD mode.
