electrocardiogram (ECG) on the skeletal musculature
using the three standard Einthoven limb leads I, II
and III:
Lead I: from right arm to left arm;
Lead II: from right arm to left leg;
Lead III: from left arm to left leg.
The three leads can be selected by push-button and
the choice is indicated by an LED.
The equipment works by measuring the changes in
skin surface potential caused by contraction of the
heart.
