> I find that amazing. Here, the mains electricity supply is 230-240 Volts and the ECT machine goes up to 450 Volts! Someone please correct me if I'm getting confused. My understanding of electronics is very poor :-S

what is amazing for you? The voltage? Is it low or high in your opinion?
Actually if we consider safety, voltage is not dangerous, the most important is current which comes into the heart i.e. safe current is max 10 mA. It depends on resistance of your body (if electrodes are put to your hands) and voltage i.e. I = U/R.
However I don't know how it is if electrodes are put onto your brain. Certainly heart is not affected at all. What is the safe limit in that case, this is difficult to say as norms usually don't assume that current comes through your brain.
