LOINC Code


LOINC code91546-2
nameST deviation (Maximum value during study) by EKG
descriptionST-segment deviation represents the maximum ST deviation during a procedure such as an exercise stress test. In some contexts the maximum ST deviation may be defined more specifically, such as in the Duke Treadmill Score, which states that the ST deviation measurement should exclude any leads other than aVR that have pathological Q waves, and that it can be calculated during or after exercise.

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
