Usually this happens when someone gets too close to a refrigerator; once in a Prius.
That the device survived a lightning strike is pretty awesome. I would MRI her head to make sure that there was no unintended ablation from the extra current through the implanted electrodes, however.
*edit - I guess she was not struck by lightning, but her house was.
An MRI with any metal effected by strong magnets in your body can be deadly. The least of your worries would be tearing the implant out through your skin. My lung doctor saved me from that when I was brought in unconscious in an emergency. My wife tells me he went down the hall at a full run... I have an ICD implanted.
There's specs for current Medtronic DBS systems (machine configured below certain RF power, 1.5 tesla magnet, specific head coils), as long as you stay within them, it's ok. Boston Sci/St Jude ones are "probably" compatible" but has not had FDA approval for MRIs yet.
There are MRI-safe ICDs now. So they can be designed to avoid heating and mechanical displacement in MRIs. For ones not designed for this, such as yours apparently, it can be deadly though.
