MI and T Waves

Ok, I am trying to find a particular answer that has stumped me to no end. I need to know if a patient that has had an MI will or will they not have elevated T Waves? I have been searching all over the internet with no luck. Everything refers back to the Q wave which is not the answer I am in need of. Can you please help?  Thanks so much!

I think your question doesn't actually have a specific answer - during and after myocardial infarction you will often see T wave abnormalities but as time passes and the injured site heals the T wave may return to normal or maintain some degree of "abnormality".  As to specifics of the T wave (positive, negative etc) it apparently varies according to the location and severity of the given infarct.  I agree with FFMEDIC that ST segment elevation and depression is more consistent in regards to MI.

The above article details two groups of patients with infarcts whose ekg held opposite T-Wave ekg patterns post MI depending on the location/severity of the MI.  Hope that helps somewhat.

Hi,

Do you mean elevated T waves as in "peaked", if so this can an indication of hyperkalemia.  

If a person is actively having an MI they will have elevated ST segments in the leads associated with the area of there heart that is being damaged.

The Q wave that you read about is a sign that can be seen on the EKG that indicates someone has had an MI in the past, greater than 24 hours ago.

Hope this is of some help...

Thanks thats a good idea. An MI is mycardial infarction and yes the t wave is on the ECG.

Maybe it would help to spell out what "MI" is.  It will not help me help, as I know nothing about the mechanics of the T Wave (on a EKG I assume).  Still, more information from you may help get useful input.
