The interpretation of depressed ST segments depend on the location, as well as the medical history. A list of causes, though, are: Ischemia (lack of oxygen to certain heart tissues) Myocardial infarction (heart attack) Hypokalemia (low potassium) Normal variant Enlargement of heart ventricles Medication effect of Digoxin and more...

A depressed ST wave can mean a number of things. It can be caused by some medications (digoxin), by ischemia in the heart muscle, and also by a myocardial infarction on the posterior surface of the heart (if seen in V1 or V2). ST depression may also be seen as a reciprocal change in leads away from the site of the myocardial infarction.

What does st deviation mean on a cardiology report?

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.


What does the abbreviations STEM and non STEM mean in connection with ST segment?

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.

What does the medical abbreviation STEMI mean?

STEMI stands for ST-segment Elevation Myocardial Infarction. The ST in this case doesn't stand for anything; it refers to the part of the EKG tracing that is higher than usual (elevated). Patients with STEMI may benefit from treatment to restore flow to the heart muscle.


What does an st elevation on an ekg mean?

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.

What does myocardial ischemia look like on an ECG?

The ECG sign of subendocardial ischemia is ST segment depression. Note that ECG is used more now that EKG.


What are three different ways an EKG might warn of a heart problem?

ST elevation would indicate a heart attack (MI). A Q wave would indicate an old MI. A fast heart rate >120bpm may be significant if the patient is not already being treated for conditions such as SVT. Bradycardia <60bpm may require pacing.


What is a nonspecific st-t wave change?

Nonspecific st-t wave changes do not indicate a heart attack. These changes are often dismissed by doctors, and there is no further investigation, despite the fact that their could be a pulmonary embolism or cardiac problem.
