Z-Scores of Cardiac Structures | Wessex Data

These are the default z-score equations currently used on KinetDx/syngoDynamics workstations...
Z scores of 15 cardiac structures including the mitral valve, aortic valve, pulmonary arteries, etc. Regression equations were derived relating cardiac dimensions to the size of the body using a population of 125 normal infants and children. From the Wessex Cardiothoracic Unit, Southampton General Hospital, UK.
