Jun 6, 2011. up-sloping or horizontally depressed ST segment (isoelectric: top two panels; slightly up-sloping: third panel; horizontally de- pressed: fourth panel); often follows the biphasic T waves seen in 1D by hours to days. As the T-wave changes subsequently regress, the positive-negative biphasic T- waves are.
The supplementary value of varying degrees of upsloping ST-segment depression observed during treadmill exercise testing to the accuracy of the exercise ST-segment response for detection of ischemia was determined by employing a reversible thallium-201 (201Tl) defect as the criteria for ischemia. A group of 199.

In the present study we present criteria based on upsloping ST segments and compared these criteria with the conventional criteria. Using upsloping ST- segment criteria, the amount of ST-segment depression at 80 msec after the end of the QRS complex is used as a parameter (ST criterion E, with a depression of 100 mV,

A treadmill ECG stress test is considered abnormal when there is a horizontal or down-sloping ST-segment depression ≥ 1 mm at 60–80 ms after the J point.(9) Exercise ECGs with up-sloping ST-segment depressions are typically reported as an 'equivocal' test. In general, the occurrence of horizontal or down-sloping.

sloping ST segment of 0.08 second or more from the. J point, ST depression at least 1 mm below the isoelectric line, and other features,g-'3 sometimes depending upon the leads used.14* l5 This report does not discuss elevation of ST segments which may occur during or after exercise.16 It relates solely to depression of.
ST depression refers to a finding on an electrocardiogram. Contents. [hide]. 1 Measurement; 2 Physiology; 3 Causes. 3.1 Mnemonic. 4 See also; 5 References. Measurement. ST segment depression may be determined by measuring the vertical distance between the patient's trace and the isoelectric line at a location.
A down sloping ST segment. What does this arrhythmia look like? (describe it) ST segment depression is often characterized as "horizontal", "upsloping", or "downsloping"

Horizontal or flat STs are also quite suspicous for ischemia. Upsloping ST depression is only about 60% accurate for diagnosing ischemia. “J point” depression at the beginning of the QRS complex is not significant if the location of measurement (two boxes past the QRS) finds the ST segment has risen back to the baseline.
