what does t-wave changes in an ecg mean?
Question:
Answers:
ecg or ekg is the electrocardiogram. The heart cycle is the entire PQRST curve, so the T is the final part of that set of several electrical changes that happen to the heart during one beat-cycle. The t-wave is the final (third) wave, and is a dome shaped upward deflection that indicates ventricular repolarization, when the ventricles are starting to relax. T wave is smaller and wider than the QRS complex because repolarization occurs more slowly than depolarization.
BTW, t-wave can be elevated in hyperkalemia, high blood potassium.

I believe that means that there is a glictch in the ventertricular repolarization.
