Macruz Index is a proportion between the P wave duration and PQ segment (not interval) duration (P/PQ). The idea comes from observation, that there's an inverse proportionality between those two values.
With reference range between <1;1,6>, Macruz index >1,6 indicates P mitrale, while <1 indicates P pulmonale (but diagnostic value of the latter is less significant).

See also Morris index.
