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 ischemia or LV overload mean in an ekg?
Ischemia on an EKG indicates a lack of blood flow and oxygen to the heart muscle, often resulting in characteristic ST segment changes, such as ST depression or T wave inversion. Left ventricular (LV) overload refers to increased pressure or volume in the left ventricle, which can manifest as peaked or widened QRS complexes, and may indicate conditions like hypertension or valvular heart disease. Both conditions can lead to significant cardiac complications if not addressed.

What are five carcliac conditions that change your EKG?
Five cardiac conditions that can alter an EKG include myocardial infarction (heart attack), which can cause ST-segment elevation or depression; atrial fibrillation, characterized by an irregularly irregular rhythm; ventricular hypertrophy, which may present with increased voltage and changes in the QRS complex; ischemia, often shown by ST-segment depression or T-wave inversions; and bundle branch blocks, which manifest as a prolonged QRS duration with specific morphology changes. Each of these conditions affects the heart's electrical activity, leading to distinct EKG patterns.
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.
How does the variety of exercise on the circulatory system affect an EKG reading?
The variety of exercise influences the circulatory system by increasing heart rate, stroke volume, and overall cardiac output, which can be reflected in an EKG reading. During exercise, the heart's electrical activity may show faster rhythms, changes in intervals, and variations in waveforms, indicating increased demand for oxygen. Additionally, different types of exercise can lead to specific EKG patterns, such as ST segment changes or T wave alterations, depending on the intensity and duration of the activity. These changes help assess cardiac function and fitness levels.
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 are lateral ST changes on an EKG?
Lateral ST changes on an EKG refer to alterations in the ST segment that occur in the lateral leads, specifically leads I, aVL, V5, and V6. These changes can indicate ischemia or injury to the lateral wall of the heart, often associated with conditions like myocardial infarction or coronary artery disease. Elevation or depression of the ST segment in these leads can help clinicians identify and localize cardiac issues. Proper interpretation of these changes is crucial for timely diagnosis and treatment.
