Key result
Conventional electrocardiogram indices of ventricular repolarization heterogeneity are not specific to hypertension and should be used with caution when attempting to estimate blood pressure values.
Caution is needed when attempting to evaluate blood pressure values using only conventional indices of an ECG, as increased ventricular repolarization heterogeneity is not specific to hypertension.

Tatsuya Sato (2021) conducted an editorial in Hypertension. Electrocardiogram features (QTc dispersion, Tpeak-Tend, P wave dispersion) was evaluated. Conventional electrocardiogram indices of ventricular repolarization heterogeneity are not specific to hypertension and should be used with caution when attempting to estimate blood pressure values.
