ECG Electrodes

Using only electrocardiograph (ECG) electrodes tested specifically with regard to the MRI environment is strongly recommended to ensure patient safety and proper recording of the electrocardiogram. Tests should include an evaluation of magnetic field interactions, MRI-related heating, and characterization of artifacts.

Various ECG electrodes have been specially developed for use during MR procedures to protect the patient from potentially hazardous conditions and to minimize MRI-related artifacts.

The List provides a compilation of ECG electrodes that have been evaluated for MR-safety using MR systems operating with static magnetic fields up to 1.5-Tesla. Some have been assessed at 3-Tesla, as well. Importantly, these electrodes should be used according to the guidelines provided by the manufacturers of the ECG monitoring devices.
