That's a lot for you to handle - not only the kidling, but even as a non-parent I can imagine the worry you have, and trying to protect him as best as you can. And it's not always easy to decide what's worth what risk or not.
Oh, and to continue aswering bits completely our of order, yeah, implantable defib. I dunno, it made me nervous, especially since as far as I can tell, my risk of cardiac arrest seems low. And my heart attacks are getting less bad - I had four STEMIs, then two NSTEMIs, and the last one was IIRC an NSTEMI Type 2 which is one they wouldn't've even detected a few years or so ago. heh
