What Does Nonspecific St Depression Mean?
Thus the term, nonspecific ST-T wave abnormalities, is frequently used when the clinical data are not available to correlate with the ECG findings. Factors affecting the ST-T and U wave configuration include: Intrinsic myocardial disease (e.g., myocarditis, ischemia, infarction, infiltrative or myopathic processes)

.

Accordingly, what does ST depression on an ECG mean?

ST depression refers to a finding on an electrocardiogram, wherein the trace in the ST segment is abnormally low below the baseline.

Beside above, why does ST segment depression occur? ST segment depression occurs because when the ventricle is at rest and therefore repolarized, the depolarized ischemic subendocardium generates electrical currents that are recorded by an overlying electrode.

Considering this, is ST depression serious?

CONCLUSIONS: In unstable coronary artery disease, ST-segment depression is associated with a 100% increase in the occurrence of three-vessel/left main disease and to an increased risk of subsequent cardiac events. In these patients an early invasive strategy substantially decreases death/myocardial infarction.

What is the difference between ST segment elevation and depression?

The electrical potential difference exists between ischemic and normal myocardium and it results in displacement of the ST segment. The ST segment may be displaced upwards (ST segment elevation) or downwards (ST segment depression). The term ST segment deviation refers to elevation and depression of the ST segment.

How is ST depression treated?

It is concluded that provided ST-depression during treatment with B-blockers is correlated to myocardial ischemia in the same way as without such treatments used, other factors, e.g. an increase in cardiac size, will contribute more to the ischemia. labetalol may cause less increase in cardiac size than propranolol.

Why STEMI heart attacks are so deadly
Unlike skin or hair, once heart muscle is damaged, it will never grow back. All heart attacks are serious, but one type of is the most dangerous of all and it's known as a STEMI (ST segment elevation myocardial infarction), or a widowmaker heart attack.
