Across the chest? The 10 mA rule has been our books for 30? years. Cardiac Arremia(SP).
I remember as a electrician in the 60's that the rule was >100 ma would be a likelyhood of death. Under 100 ma and you would probably not die. The chart I posted agrees with that.
75 mA to 100 mA threshold of cardiac fibrillation (probability 0.5%)
250 ma cardiac fibrillation with 99.5% probability (for an exposure time of 5 seconds)
