I can't believe he's ever done that before, since the nipples generally provide a path directly through or near the heart, and a powerstrip would so oversupply the current as to pretty much nail closed the coffin.
Not really. It's not something I'd do, but the way the M.D. explained it to me, the current is so high that it stops the heart for a while, but needn't always induce arrythmia or fibrillation. Actually, at a party, when someone went into cardiac arrest, a crafty cardiologist, who was at the same party, successfully improvised a defibrillator with a lamp cord with a switch on it. Granted, there's a fucking huge difference between a trained cardiologist performing a last-ditch effort at preserving the life of someone that has gone into fibrillation already, and some clueless twat that tries to use it as a form of sexual play. Also, additionally covering her mouth with tape tells me he probably does not have the requisite intelligence to live among the general public.
Again, if you know exactly how to do electroplay in that area, or have a unit that is designed for it (medical grade current limiting, etc.), it's entirely possible to do similar things in a manner that some might deem an acceptable risk. But I would advice anyone who insists on trying it to acquire a cardiac compression unit (a thing you strap around the chest which will compress the entire cavity without breaking the ribs, but hard enough to ensure sufficient circulation; it requires very little training to use, and is superior to a defibrillator for most uses- the air ambulance doctors use it around here) and a manual ventilator.
Either way, though, there doesn't seem to be anything RACK about what he did, let alone SSC.

The current DOES stop the normal cardiac cycle. Either it induces the fibrillatory response by striking at the very vulnerable moment where the heart is not yet prepared for another electric impulse from it's own pacemaker cells (known as R on T phenomenon) or it depolarizes the heart's pacemaker cells and the conduction system rendering them incapable of functioning. That is more often than not, permanent. There are many other factors in the equation -- amperage is most important, voltage in certain circumstances (usually industrial), skin resistance, biphasic vs monophasic conduction, AC vs DC, etc. The ventricular fibrillation threshold of the human heart is generally between 75 and 100mA (seen as low as 60 in certain physiologic states), The unfortunate situation is that with the contractility of the cardiac fibers -- they're all pacemaker cells AND muscle -- anything over 200mA usually wrenches the heart down in a spasm that does not ever release. This is also the same contractions that causes the "can't-let-go" condition that locks the victim to the wire, appliance or device. Excessive amounts of current (>1A) cause immediate ventricular arrest without any sign of fibrillatory response. (Rare cases like that have been resuscitated where there was immediate loss of causative current AND no thermal destruction of the heart AND immediate advanced cardiac life support intervention.)
My specific references to VF threshold and high amp VA attributed to Dimaio, Vincent J., and Dominick J. Dimaio. Forensic Pathology. Boca Raton, FL: CRC P, 2001.
There is a gross difference in the purpose of an external compression machine (known as a Thumper) and an external defibrillator. Thumper units are used in ambulances to free up the hands of the attendant (if you're manned with only a physician, he can't be pushing drugs and maintaining the airway if he's having to do 1:1 cardiac compressions. Defibrillators are used to either create a synchronized cardiac conversion of a rhythm OR to halt the fibrillatory response of the myocardium in instances of a lethal arrhythmia such as those induced during electrocutions. The Thumper unit DOES NOT replace the defibrillator and it is NOT a superior device or a replacement for an invasive device such as an defibrillator. (And I am a certified healthcare professional who has used external and internal defibrillators in the field, the ER, the trauma OR and the cardiac elecrophysiology lab.)
