WebT peak -T end (T p-e) is the distance between T-wave peak point and the returning point to the isoelectric line. The T p-e interval reflects the transmural dispersion of repolarization [50]. Some studies revealed a relationship between T p-e and ventricular arrhythmias, heart failure, and sudden cardiac death [51,52]. WebA common cause of abnormally large T-waves is hyperkalemia, which results in high, pointed and asymmetric T-waves. These must be differentiated from hyperacute T-waves seen in the very early phase of myocardial ischemia. Hyperacute T-waves are broad based, high and symmetric.

WebPeaked T waves poorly predicted the serum potassium levels in both full and test sample (R 2 = 0.03 and R 2 = 0.01, respectively), and also poorly predicted hyperkalemia. The selection algorithm based on Bayesian information criterion identified T wave amplitude and use of loop diuretics as the best subset of variables predicting serum potassium.
