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...

What does to EKG look like with aortic stenosis?
the ekg of aortic stenosis showsleft ventricular hypertrophyleft ventricular strain due to pressure overload such as depressed st segments and t wave inversion in leads 1 ,avl ,v5 and v6left atrial enlargement
What wave of the EKG occurs during depolarization of the ventricle?
QRS
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 is the point of union between the s wave and the st segment called?
This is the point where the S wave and the ST segment meet, is called J junction.
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 is calumet college of St. Joseph home of?
The Crimson Wave
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.
How can EKG identify a myocardial infarction?
An EKG tells us about how electricity flows through the cells of the heart. Any infarction of cardiac tissue causes changes in the way the electricity travels. An EKG can show us these changes and help us to even identify where the infarction is occurring. A 12 lead EKG must be done to truly identify any infarction. The 12 lead shows us 12 different views of the electricity as it moves from one lead to another. By comparing the views we get against what would normally be expected and comparing each lead to the others we can look for changes in the EKG pattern (ST elevation or depression is the most obvious, but many other changes exist).
