BSA-adjusted z-scores for left-sided pulse wave Doppler and tissue Doppler imaging routinely used in a clinical setting.

As Z scores describe the normal limit of a healthy population, other studies are needed to further define the threshold above which health becomes a disease by integrating other important factors such as ventricular morphology, loading condition, and HR.

Note: this is a work-in-progress; there are 13 PW and 14 TD measures... these are the most common. Others will get rolled out as time allows.
