Recent medical data suggests that there is a very vulnerable "instant" in the heart beat cycle where electrical shock is vastly more fatal... The doctor that discovered it, killed himself trying to study it
You are referring to the T-wave repolarization phase of the heartbeat. It is at this point that a delivered electric shock of the right amount of joules (external or internal) can induce ventricular fibrillation. EPS physicians do this when testing AICD devices to make sure they work in the patient.

...could flow through the body to ground.
Yeah, and if I understand it correctly, the HV component effecively lowers body resistance and lets more current flow, now that it's available...
I wouldn't suggest it. A grounded screwdriver in a piece of PVC is just as fun. I did get bit by my SGTC once (I was running about 42" at time), I only felt it where it jumped out my ankle, but really, under the right conditions I could have been dead. Not a pleasant thought.
I'll do it on little SGTC coils (like LITTLE as in flybacks at low power). You can still touch something you shouldn't. I wouldn't wish a SSTC burn on most people, I never touch those.

CW SSTCs are dangerous in that you could easily get deep tissue burns without realising until all too late. I'm more careful about getting burns from nearby metal objects.. floating grounds, etc, around an SSTC.
SGTCs tend to be bigger, scarier and the sensation isn't so agreeable. The noisiness of the sparks and gap acts as a natural deterrent, too.

None is proven to be directly lethal, unless you are of very bad health or something.
Shock from disruptive is somehow similar to a large VDG and cant be very unpleasant, but hardly lethal. You can get yourself killed; if you do various stunts, sit on topload or etc. and start a power arc to primary circuit, mains or etc; touch wrong part of primary circuit, set a chain of events that lead to primary-scondary flashover, power arc and you get yourself killed again.
Normal (non-DR) SSTC's can hardly reach SGTC power levels, they usually operate 'just' on mains voltage and it's usually harder to start power arcing to something.
Sparks may leave horrid burns but nervous and other effects areusually omitable.
You can use common sense with SSTC's; only effect it does is heat, adn I can for example touch the arc briefly same way as I would touch flame of ciggarete lighter or etc.
Large CW arcs are not going to be touched for same reason you wouldn't touch a blowtorch flame or burning log.
Even if you hold some piece of metal in hand you can still have too much contact resistance and torch your hand.
