The industry standard is 12 lead.


Bob, this troll failed because my wife is actually a nurse at a leading
heart hospital. They use 9-10 leads. If you want to ease off on the
googling, try picking up of a copy of Brunner and Suddarth's Textbook
of Medical-Surgical Nursing. Placement is shown with 9 leads. Which
lead is the best indicator, Bob?

Kinda silly. This is like your efforts to google up a background of
sailing. No "smackdown" or "Kaboom." Just sort of embarassing for you.
You've fallen far, my friend.

G'night.
