This is particularly interesting. My husband had a cardiovascular/defibrillator implanted for eight years. Never had one event or blip, just weeks before during a checkup his cardiologist even commented that it might not have been necessary. In 2009 He sold a large HYBRID Cadillac Escalade SUV to a good friend and went to the service area to make sure it was perfect for delivery. The large battery area was open and he leaned in to look, almost immediately his defibrillator went off and and subsequently another eighty times until he got to the ER. A long story but eight months later he had a heart transplant. . It might have been a coincidence that he was very close to the the battery compartment when it happened, we always thought it had something to do with it, did a little research and there were a few studies at the time that alluded to possible issues.
I can't tell you how sorry I am about this. I've been defibrillated a few times and it hurts like hell. LIKE HELL!!! I was recently defibrillated externally (maybe unnecessarily.) in the ER and that hurt even worse. Unbelievable pain! On a scale of 1-10, it was about a 30.
Was he conscious during all of those 80 defibrillations? So, I really feel sorry for your husband. It's hard to know if leaning into the battery compartment had anything to do with it or not. If you can prove it there might be a legal case.
