These online calculators were developed based upon the published data referenced on their respective pages. Users are encouraged to read the source literature and verify the calculations themselves.

Please Note: Although these z-score calculators are based upon published literature, I do not vouch for or endorse their suitability nor do I defend the conclusions of their authors. Interested readers are directed to the following "pediatric echo z-score suggested reading":
