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)
