A:Answer I would not, my first watches specifically said not to. Any consumer electronic devices, such as cell phones and smart watches, should at least six inches away from implanted medical devices, especially cardiac defibrillators. I wouldn't want to take the risk myself. I certainly don't recommend it as your arm can come within those parameters. I am not a scientist or a smart watch technology developer and this is purely my opinion and should not be used as an endorsement whether to buy this smart watch or not. Please do your own research before making this decision.
