Ask the doctors. A catalog advertises a home defibrillator for less than $1,300 with no prescription required. My internist said he wouldn't have one of these things in his house because they were unsafe. A longtime friend of mine died recently at 61, my current age, so I'm particularly interested in whether you think buying a defibrillator is a good idea.
