May I suggest you contact Medtronic and asked that question.

I am not sure if Medtronic is like Boston Sceintific and have a patient friendly information. I have been able to asked Boston Scientific specific answer to things like this that answer directly to ICD/Pacemaker model. It is important your information answers or reseach you do on line directly uses your model you had implanted.

I have used Boston Scientific for direct answers many times. I once put my smart key right above my device and got a pacing. Boston Scientific said could happen. My pace clinic said did not think so. Recently my pace clinic warned me about getting to close to underwater lights in our fitness pool as could be picking up electrical if light not properly grounded. This was due to me reporting device pacing me.

If your father just had it implanted it probably is a newer version and protected from many of the things that would affect older devices. But you are in a chair with electrical current all around it. I would asked Metronic directly as well as your cardilogist. Just remember your device manufacturer will have tons on informatino on their research and complaints.

I hope this helped and you find Medtronic patient web site as helpful as I found Boston Scientific.
