Limb Lead Reversal In order to understand why the leads look the way they do, we must recall Einthoven’s triangle. As for the aVL/aVF reversal, we must remember that aVL/aVF/aVR are all augmented leads (hence the a) and rely on interpreting their view of the electrical activity of the heart as an average of two limb leads.
