What is it indicated for?

For use only by a digital device to measure ST-segment shifts.

Assessment of real time ST segment analysis in adult patients.

The MIDATm Algorithm Rev. B is intended for use in the hospital environment for the following patient population:

Ages: 33-82 years

Heights: 147 to 185cm (58 to 73 in.)

Weights: 53 to 118kg (117 to 261 lbs.)

Height to weight ratios: 1.41 to 2.99 cm/kg (0.25 to 0.54 in/lb)

The use of EASI leads implies that the results may not be of diagnostic quality.

Indications for use as stated in the FDA summary.
