Does anyone here have a pace maker/defibrillator?

Title is pretty self explanatory. With the number of people in here I assume someone does. I just got one and they told me a couple tools I couldn't use because it makes the unit think you're in arythmia and shocks your heart. One of the tools is a chain saw, obviously from vibration. I'm trying to make sure the DA's don't have the same affect, without finding out the hard way. Any help would be greatly appreciated.
