abnormal EKG, what does a "high T wave" mean?

Answer 1

EKG's have a range of normal. If someones' said high T waves, it might be normal for them, they might always have that finding. T waves can also go 'peaked' if the potassium is high, or sometimes from certain medications. If the ST is high, then that could mean ischemia, or injury (heart attack) That's all I can add.

Answer 2

The T wave is the most labile wave in the ECG (or EKG, abbreviated from the German Elektrokardiogramm). T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads. Also, the normal T wave is asymmetric with the first half moving more slowly than the second half. In the normal ECG, the T wave is always upright in leads I, II, V3-6, and always inverted in lead aVR. The other leads are variable depending on the direction of the QRS and the age of the patient. T wave abnormalities on resting ECG should be given special attention and correlated with clinical information. Risk factors for major Q/QS patterns need not be the same as traditional risk factors for clinically recognized CHD. High lipoprotein (a) levels may be a stronger risk factor for silent myocardial infarction (MI) compared to clinically recognized MI.This is a very brief explanation. For a full explanation you would be advised to consult your doctor for details of your result.

Answer 3

T Wave

The T wave represents the repolarization (or recovery) of the ventricles. The interval from the beginning of the QRS complex to the apex of the T wave is referred to as the absolute refractory period. The last half of the T wave is referred to as the relative refractory period (or vulnerable period).

In most leads, the T wave is positive. However, a negative T wave is normal in lead aVR. Lead V1 may have a positive, negative, or biphasic T wave. In addition, it is not uncommon to have an isolated negative T wave in lead III, aVL, or aVF.

* Inverted (or negative) T waves can be a sign of coronary ischemia, Wellens syndrome, left ventricular hypertrophy, or CNS disorder.
* Tall or "tented" symmetrical T waves may indicate hyperkalemia. Flat T waves may indicate coronary ischemia or hypokalemia.
* The earliest electrocardiographic finding of acute myocardial infarction is sometimes the hyperacute T wave, which can be distinguished from hyperkalemia by the broad base and slight asymmetry.
* When a conduction abnormality (e.g., bundle branch block, paced rhythm) is present, the T wave should be deflected opposite the terminal deflection of the QRS complex. This is known as appropriate T wave discordance.

Whether one endeavored to conform to the higest expectation or the central tendency, to be an "average person" would require superior ability! If I had to choose I guess I would choose the "Freaking Genius". I think it would help me be able to set the time on my VCR and figure out why I can't get sound on my computer (despite having all the drivers and no conflicts, etc.). Or perhaps, as a genius I wouldn't care about such mundance things, prefering to devote my time to "higher pursuits" such as figuring out what the leaves on a tree weigh (a recent intriguing Yamster question) or when to use "quotes". Most importantly I could better calculate how much bleach to use in my laundry. While these questions may not seem all the worthy when matched up against discovering the cure for cancer or finally developing a theory of everything, I believe they are connected. I'm just not sure how, of course, because I don't quite tip the scales at the genius level, even fully clothed. I'm sure if I did, I would know enough to say that everything is connected since it sounds very profound. I'm not as inclined to go for "YOU the Freaking Genius" because that seems to imply that my most identifying characteristic is being a genius. I would hope that my interpersonal interactions would remain broad and rich enough so that I could remain simply "YOU" or me, depending on your perspective.. However, I could live with "Just You" since it has allowed me to build up a tremendous credit of incompetencies, providing built in excuses and even expectations for my daily mishaps. As far as 10-12 are concerned, I. like all parents KNOW that my child is a unique and special gift to the world with extraordinary talents that often reflect the fact that he/she is an evil genius! 13- Perhaps God can say that. For the rest of us, the best we can do is to say "I AM WHO I AM MAYBE"

Tall T Waves

Answer 6

What does ST segment elevation mean on an EKG?

Answer 7

Greater than 10mm in precordial leads or greater than 5mm in limb leads can be an indication of hyperkalemia. You really need to have your physician discuss all test results with you. He/she knows you and I don't.
