CoBro,

Not being a doctor I was unsure of just what that was also. I knew it had to do with the heart so I did a search and here is what I found.


The ST segment refers to a portion of the electrocardiogram (ECG)waveform.

This portion basically represents electrical waves coming from your heart as heart cells recharge themselves in between heart beats.
Doctors look at this portion to access the health of the cardiiac muscle. Essentially they look for either ST segment elevation or ST segment depression.

ST elevation: implies an ongoing acute myocardial infarct (fancy lingo for heart attack where heart cells are dying)
ST depression: implies ongoing ischaemia (fancy lingo for saying too little blood going to the heart without cells actually dying)

The ECG composes of many other components other that the ST segment and all these add to the final picture and a fuller interpretation of the health of a patient's heart.
