Implantable pacers and defibrillators use Lithium chemistry batteries (originally Lithium Iodide) typically around 3 VDC (BOL about 3.15 VDC, EOL about 2.62 VDC). The typical output pulse to the heart to pace the heart is about 2.5 VDC at about .3 mSec pulse width. However, they can be programmed up to about 8 VDC at 1.6 mSec pulse width.

Another pathological example is the implanted pacemaker. How much voltage does it use. I bet way less then what's inside a 9V battery. But the location and the firm contact it makes means very little voltage is required. One of the odd things about humans is that compared to other animals we are very tolerant of electrocution. Anyways the entire thread is kind of pointless the very first thing I looked for when I wanted to measure AC line frequency was my 6V AC wall wort power supply on the teary that the 6V secondary would match the AC mains frequency.. I'd guess that anyone would think of a low voltage transformer Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
