statusACTIVE

Fully-Specified Name

componentEnd-systolic volume/Body surface area
propertyArVol  =  Volume/Area
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemHeart.atrium.left
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
methodUS.2D+Calculated by area-length method

type2  Clinical
order vs. observationObservation
formula (readable)LA volume/BSA = {[8/(3 x Pi)][(A1 x A2)/L]}/BSA, where A1 and A2 represent left atrial area in the apical 2-chamber and 4-chamber views, respectively, and L is the shorter of the two left atrial lengths measured in the same 2- and 4-chamber views.

Associated Observations

LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.
