Correct answer: B — Deactivate ICD function; reprogram pacing to asynchronous if pacemaker-dependent

CRT-D + EMI risk: deactivate ICD (prevents inappropriate shocks from diathermy), reprogram pacing to DOO/VOO if pacemaker-dependent (prevents EMI-induced inhibition). Cardiac physiologist pre/post-op. External defibrillator immediately available.
