BCC: Dr K : Yes?

> 1. Why is it called the "right leg driver"? Why can't it be the left leg?

Tradition / Heart relative./ ~~=3D Neutral point.
Some other reference points would do OK but this is what was chosen
for various reasons and once chosen that's what's used.

Waveforms seen at all points are relative to this reference and will
be different when seen wrt  any other.
Experts are skilled at glancing at waveforms and learning what they
tell them about the heart. Measure from somewhere else and all
waveforms will change.
