"We have all been taught that it takes 100ma across the chest cavity to kill us"
That is NOT an established axiom, nor is it true. The amount of current needed to interfere with and stop the heart is a few mA or less. Because of this, all biomedical equipment in clinics and hospitals uses special low-capacitance transformers to avoid the possiblity of shock. The UL standard for leakage current of Class II devices in the patient care area is 150uA.
