What does Upsloping ST depression mean?
Conclusion. Upsloping ST depression in resting electrocardiogram may indicate cardiac ischemia in the presence of active cardiac symptoms. In the absence of ongoing symptoms however, it may be secondary to conditions other than ischemia.
What does ST depression in inferior leads mean?
ST depression refers to a finding on an electrocardiogram, wherein the trace in the ST segment is abnormally low below the baseline.
What depth of ST segment depression is significant?
ST segment depression less than 0.5 mm is accepted in all leads. ST segment depression 0.5 mm or more is considered pathological. Some expert consensus documents also note that any ST segment depression in V2–V3 should be considered abnormal (because healthy individuals rarely display depressions in those leads).
What does a depressed ST segment indicate?
ST depression in ECG at entry indicates severe coronary lesions and large benefits of an early invasive treatment strategy in unstable coronary artery disease; the FRISC II ECG substudy.
Can anxiety cause ST depression on ECG?
Anxiety-related ECG changes
The ECG changes in anxiety are: ST flattening, the commonest finding. Frank ST depression; not rare, especially in hyperventilation.
Can heart failure cause ST depression?
Heart failure may cause ST segment depressions in left sided leads (V5, V6, I and aVL). These depressions are horizontal or downsloping.
How do you treat ST depression?
A person may treat the underlying condition that is causing their ST depression. A person with an ST depression may also wish to make some lifestyle changes to help improve their heart health. This can include eating a healthy diet, getting regular physical exercise, avoiding smoking, and maintaining a moderate weight.
Is ST depression normal during stress test?
Interpretation of the treadmill ECG stress test
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.
