| name | Right ventricular Minor axis at end diastole [Length] by US.2D.A4C | ||
| description | The right ventricular minor axis is measured in the apical four-chamber view as the distance between the lateral right atrial wall and interatrial septum, at the midatrial level defined by half of right atrial long axis. [PMID: 25559473] | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Minor axis.end diastole | ||
| property | Len = Length | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Heart.ventricle.right | ||
| scale | Qn = 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 | ||
