A 1.5T MRI‐conditional 12‐lead electrocardiogram for MRI and intra‐MR intervention

High‐fidelity 12‐lead electrocardiogram (ECG) is important for physiological monitoring of patients during MR‐guided intervention and cardiac MRI. Issues in obtaining noncorrupted ECGs inside MRI include a superimposed magneto‐hydro‐dynamic voltage, gradient switching‐induced voltages, and radiofrequency heating. These problems increase with magnetic field. The aim of this study is to develop and clinically validate a 1.5T MRI‐conditional 12‐lead ECG system.
