not wipe off the disinfectant.
Compared to the walls of the left ventricle, the walls of the right ventricle are
thin. - ANS -True
In a typical 5 lead configuration, where is the white electrode (RA) placed? - ANS -
The white electrode (RA) is placed at the infraclavicular fossa, close to the right
shoulder.
