 ST depression vs. ST elevation

Dear Dr. Chung,

I am an RN collecting preoperative risk data for cardiac cases.  One of the
items I capture is ST depression >1mm.  I only have basic training on EKG
interpretation, and must rely on the documentation provided by the
cardiologist or other physician who read the EKG.

More often than documentation of ST depression, I seem to see documentation
of ST elevation in the medical record.

According to my understanding, ST depression is an indicator of ongoing
cardiac ischemia.  I'm curious about the meaning of ST elevation.  It seems
like this, too, is worrisome for acute MI.  Would you be so kind as to help
me understand what the distinction is between the two findings?

Thanks very much.

ST Elevation indicates myocardial infarction or pericarditis.  You should
learn to read ECGs yourself, because you will need to standardise your
findings.  To rely on operative notes is fraught with danger.  ST depression
can be caused by use of digoxin or electrolyte disturbances, for example.
You'll need to have a standard way of incorporating this into your research.

ST depression may also occur early in MI or be present in a
contralateral lead.

ST elevation also may be present in aneurysm and occur to a small amout
as a normal variant.

Thanks to all for the help.  I do hope to get more formal training in EKG
interpretation, soon.
