The cardio Z App calculates Z-scores for pulsed Doppler measurements. These include tissue Doppler velocities, time intervals and derived indices such as the myocardial performance index and E / e’ ratio.
Pulsed Doppler velocity Z –scores calculated from the data of Eidem et al (2004) (Houston)
E / e’ Z –scores calculated from the data of Eidem et al (2004) (Houston)
Essential information for the calculation of the particular Z-score is highlighted for the user.
The App includes diagrams of how measurements were made in the reference used, so help is never far away. The example below shows the measurement used for pulsed Doppler velocities
