Mended Hearts Open Forum

I finally started Cardiac Rehab last Friday.  At my first session, they told me that I have a T-Wave abnormality.  I asked for more information about it, but they really poo-pooed it.....just said it was no big deal, that 40-50% of their patients had it, and we were "going to work on it" in rehab.  They also told me that it had shown up in my previous EKGs....which was news to me because no one has ever mentioned it to me, this was the first I had even heard of T-Waves.  

I've tried doing some research into T-waves, but it's all medical mumbo-jumbo that doesn't make much sense. Apparently it can be caused by just about anything....anxiety, drinking hot or cold beverages, position changes, etc.....but since having my heart attack has made me more nervous than normal, I'd really like to know if this is anything I need to worry about.  Anyone have any info on this??

Sorry this did not get copied
The T wave represents the current of rapid phase 3 ventricular repolarization (see diagram above). The polarity of this wave normally follows that of the main QRS deflection in any lead. The ventricles are electrically unstable during that period of repolarization extending from the peak of the T wave to its initial downslope. A stimulus (e.g. a run away heart beat called a premature beat) falling on this vulnerable period has the potential to precipitate ventricular fibrillation: the so call R-on-T phenomenon.

Hi Tracy 

An EKG has a P QRS and T wave the T wave

It can get very technical but you can learn more about it on this site.

Dear Tracy,

???????? I have inverted?? T waves, and have had them all my life. They do
not affect me at all. However, I do have to tell whomever is doing a
cardiogram that this is normal for me. MY cardiologist is not concerned,
BUT this is something that you have to discuss with yours. Explain how
worried this makes you.

Tracy,
If you're worried about it I would get a Kardia Mobil device that you can use I phone to record EKG and send it to your Cardiologist for review. I have one and use it from time to time to have my EP look at weird Afib EKG
Can buy from Amazon or Kardia..they have 6 lead and a single lead device

Dear Tracie
the cardio rehab therapists are very sensitive to what they see on the screens and what they hear when checking your blood pressure. i have learned that many doctordont tell every detail so as to not cause stress. Your cardiologist gets reports from the therapists regularly. You could call your doctor and ask your questions. Avoiding Anxiety is a big part of your healing ...so ask your questions to your doctor who will answer specific to you and your heart.!!!! the internet information is helpful but sometimes it causes more stress.
Don't be afraid to call your doctor, its their JOB to help you get well !!!
