A suggestion for unification of present limb lead systems into a single 'F' lead system

摘要

In this paper it is intended to unify the standard leda and the augmented unipolar limb lead (aV lead) system into a single lead system. Viewing form the an- gle of lead exes, the standard leads and the aV leads are not only reflecting the frontal plane vector, but are also actually complementary to each other. By now it has become quite obvious that they not only can, but also should be unified into a single system. Viewing these six leads (from standard lead an aV lead sys- tems), starting form aVL, lead Ⅰ, reversed aVR, lead Ⅱ, aVF to lead Ⅲ, an arc including approximate- ly 150 deg. C is formed.
