Marine Electrical Systems USCG Q#1105 (Set 37)

At a minimum threshold, how many milliamps of current through the body produces a condition where most people would suffer ventricular fibrillation and could only be resuscitated with a ventricular defibrillator?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 75 mA for 5 sec.

Current passing through the human body reaching approximately 75 milliamperes for a duration of 5 seconds or longer frequently induces fatal ventricular fibrillation, requiring immediate external defibrillation for potential resuscitation.
