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. WebOct 8, 2024 · Importantly, in this entity, a different clinical presentation, as well as the fact that T waves tend to be narrow and peaked (presenting a sharp apex), should be noted. [20] [21] [22] Moreover, as discussed by Xu et al., tachycardia can also be associated with the upsloping depression of the ST-segment and cTn elevation.
