This tool allows you to easily calculate the myocardial performance index (MPI). It also explores a few combinations that are possible when a series of measurements are entered, as when you intend to average repeated measures. Note: this is really intended for conventional Doppler or M-Mode techniques where the "A" and "B" terms are necessarily non-simultaneous.
Enter a single value (yawn...) or multiple, comma, separated, values.
( a - b ) / b = ?
(min. "A", max. "B")
( a - b ) / b = ?
(max. "A", min. "B")
( a - b ) / b = ?
