In the frontal lead system, the lead axes of the 6 limb leads form a hexaxial reference system, which is one of the important theories of electrocardiography.
When the frontal QRS axis is at +57, the QRS amplitude of lead  is the highest.The frontal electrical axis is almost perpendicular to aVL lead, so the algebraic sum of QRS amplitude is almost zero.
