The aVL lead is at -30Â° relative to the lead I axis; aVR is at -150Â° and aVF is at +90Â°. It is very important to learn which lead is associated with each axis. The three augmented unipolar leads, coupled with the three bipolar leads, constitute the six limb leads of the ECG. These leads record electrical activity along a single plane, termed the frontal plane relative to the heart.
