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.
The perpendicular spoke will point to the heart's electrical axis. To determine which numerical value should be used, observe the polarity of the perpendicular lead on the ECG. [clarification needed] For example, if the most isoelectric (or equiphasic) lead is aVL, the perpendicular lead on the hexaxial reference system is lead II. If lead II is positively deflected on the ECG, the heart's electrical axis in the frontal plane will be approximately +60Â°. Normal axis: -30Â° to +90Â°. Left axis deviation: -30Â° to -90Â°.
