The SCHILLER measurement program calculates the axes on the basis of the maximum deflection of the relevant
waves in leads I and aVF. The following formula is used for the calculation:
44
Vector of lead I (Q, R, S and R', S')
= (-0.24Q) + 2.6R + (-0.55S) + 0.02R' + (-0.01S')
Vector of lead aVF (Q, R, S and R', S')
= (-0.25Q) + 2.41R + (-0.66S) + 0.02R' + (-0.01S')
