A time‐varying filter electrocardiographic gating device designed to reduce NMR‐induced gradient artifacts during NMR imaging of the acutely ill cardiac patient is described. When used in conjunction with multiple electrocardiographic display monitors, accurate assessment of the electrocardiogram for morphologic changes and arrhythmias during all phases of the NMR examination is possible. © 1988 Academic Press, Inc.
