For a patient with an MR nonconditional CIED who is not
pacing-dependent, it is reasonable to program their device to
either a nonpacing mode (OVO/ODO) or to an inhibited
mode (DDI/VVI), with deactivation of advanced or adaptive
features during the MRI examination.
IIa B-NR
It is reasonable to program patients with an MR
nonconditional CRT device who are not pacing-dependent to
an asynchronous pacing mode (VOO/DOO) with deactivation
of advanced or adaptive features during the MRI examination,
and with a pacing rate that avoids competitive pacing.
IIa C-EO
For patients with an MR nonconditional CIED, it is reasonable
to schedule a complete follow-up CIED evaluation within 1
week for a pacing lead threshold increase ≥1.0 V, P-wave or
R-wave amplitude decrease ≥50%, pacing lead impedance
change ≥50 Ω, and high-voltage (shock) lead impedance
change ≥5 Ω, and then as clinically indicated.
