The Power of DefibrillationThe Power of Defibrillation

A corrective shock of 750-800 volts is A corrective shock of 750-800 volts is applied within a tenth of a second applied within a tenth of a second

That is the same voltage as 500-533 That is the same voltage as 500-533 AA batteries!AA batteries!
