Um...I've never heard of one. There's a fundamental problem with this idea. First off, I am a paramedic, and yes, I am trained in Advanced Cardiac Life Support (ie the drugs and procedures that include defibrillation). The most common rhythm that is converted by defib is ventricular tachycardia, when the heart is beating very fast. Too fast to supply itself or the rest of the body with blood. In effect, it's just quivering. Unfortunatly, if this is happening to you, I don't think you'd be conscious long enough to get to a defib unit and activate it. Other rhythms that can be converted using defib are trickier to diagnose and recognize, and often have other symptoms, so I'm not sure an automated defibrillator would pick up on them (most AEDs read the heart's rhythm through the stick on pads, they don't check any other vital signs). Now, all that being said, there are internal pacemakers and defibs that might work. These are for specific circumstances, and are generally either implanted or kept on all the time. Having an external defibrillator that you use on yourself would be highly unlikely, at least in my experience.
