I believe you are referring to STEMI (ST segment elevation myocardial infarction) and non-STEMI. These are two different forms of myocardial infarction - STEMI results in transmural (all the way through the cardiac muscle wall) injury, which results in elevation of the ST segment on EKG. Non-STEMI (NSTEMI), which used to be called a Non-Q-wave MI, is usually a subendocardial injury, which results in cardiac injury, but not as severe as STEMI. NSTEMIs do not have any elevation of the ST segment on EKG. These only have elevation of cardiac biomarkers on blood work.
Usually ST segment elevation... but it doesn HAVE to occur... many people have non st segment MI's (myocardial infarctions) where the only indicator is abnormal blood labs like high CPK or troponins
There may be st segment elevated or depressed in st deviation. The st elevation with t wave inversion is seen in acute myocardial wall infarction. The st depression with t wave inversion indicates angina pectoris.
This stands for an ST segment elevated, myocardial infarction. This is a subtype of myocardial infarcation aka a heart attack whereby the heart does not receive sufficient oxygen, commonly due to a blockage of one of the coronary (heart) arteries leading to heart muscle death. It is named so because on an ECG/EKG, you can characteristically see an elevation developing in the ST segment i.e. the end of electrical depolarisation and ventricular repolarisation over time. This is contrasted with a non-ST elevated MI aka an NSTEMI, also known as unstable angina, that does not show this classical ST elevation.
The elevation of the city of St. Helens, Oregon is 73 feet.
ST segment.
There no such city as St. Lois.
The elevation of Mount St. Helens is 8,365 feet. Prior to its famous 1980 eruption it was 9,677 feet.
The elevation of St. Petersburg, FL is 44 feet above sea level.
It's elevation is 4,605 ft (1,403.6 m).

An ST elevation could possibly be acute Ischemia and if you were given this information in accordance with a recent ECG or EKG i would not hesitate to get a second opinion or check yourself into the nearest hospital for further examination. The ST segment of an ECG represents ventricular repolarization. This basically means that the cardiomyocytes in the heart and preparing for the heart to beat once again, preparing for another cardiac cycle. When their appear to be changes in the ST segment then this represents the hearts inability to sufficiently prepare for a reoccuring cardiac cycle and may cause significant damage leading to such illnesses or medical issues as Ischaemia and even chronic cardiac failure.
