Notes
• Due to the variety of MRI sequence characteristics, if the filter recommendations below do
not provide optimum performance in all cases, the selection may improve ECG performance
during a specific scan sequence.
• ECG performance can be affected by electrode placement, the MRI procedure, the image
slice angle and slice thickness. In situations where ECG performance is not optimal, select
the ECG lead view (I, II, III, AVL, AVR, or AVF) that provides the best performance; see
page 5-17.
• For cases not requiring cardiac gating, start with the Default filter (depending on the MRI
sequence) then switch filters if a gradient artifact is noticed. If a gradient artifact is still
present, check ECG signal strength and try lead I or III.
