Augmented Limb Leads - Cardiac Monitoring.
Discussion
The heart is the "negative" pole or terminus for all augmented leads.
The sensor on the skin surface is the positive (+) pole.
Augmented leads are "unipolar" due to one sensor being on the skin surface.
The flow of electricity is measured from the heart to either the:
- right arm (aVR)
- left arm (aVL)
- left leg or foot (aVF)
