Guest guest Posted January 13, 2000 Report Share Posted January 13, 2000 Hi Debbie and welcome to our group! Feel free to talk about anything does not have to be about RP all the time, We talk about our family and just about whatever. (even mice) lol My Story-----------> <A HREF= " http://ads.web.aol.com/link/7002028/947792282/aol/ " >Relapsing Polychondritis ~ 's Story</A> ( I just updated it also) http://ads.web.aol.com/link/7002028/947792282/aol/ Nice to meet you!

Guest guest Posted January 14, 2000 Report Share Posted January 14, 2000 Hi , It's Sue... You asked about what an inverted T was. The T is part of the EKG/ECG. The EKG is an " electrical cardio-gram " , more simply it is a record of the electrical activity of the heart. It's technical... but anyways I will try and explain since cardiology was my specialty... Each heartbeat conducts what has been termed a QRS wave. There are also other parts to the ECG... The first wave is the P wave. The P wave is produced by atrial systole...contraction of the upper/smaller chamber of the heart. Next, the QRS wave is produced by the ventricular systole, in layman's terms when the pumping chamber of the heart (ventricle) contracts (pumps/squeezes). The next identified part is the T wave. The T wave represents ventricular repolarization... this is when the ventricle goes back to a resting state and the electrical activity/polarity again changes... the electrolytes potassium,soduim, magnesium are involved with this process... So anyways... this is very difficult to explain without pictures...Anyways ther are a few reasons that would causes changes in the T-wave... one is if the heart muscle is not getting enough oxygen.... this is indicative of arteriosclerotic heart disease... another reason for changes in the T-wave correlates with potassium levels.... when the potassium level is too high it causes changes in the t-wave.... This is a very basic overview.... Hope it helped a little.... SUE Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2000 Report Share Posted January 14, 2000 Sue, I am a heart patient and really appreciate this and all your info. Thanks.

Guest guest Posted January 17, 2000 Report Share Posted January 17, 2000 Jo, Anytime you have a question and I have the knowledge I would be more than happy to try and explain things to you. I know from working in the cardiovascular ICU and with the physicians.... they just don't explain things or we don't hear what they tell us or we forget.... You think of questions after they leave.... Always write down your questions and take them with you the next time you go to see your physician. Again, I will try and answer questions any time!
