JT interval (JT) was measured from the end of the QRS complex (J point) to the end of the T wave (JT end interval); QT dispersion (QTd) was determined as the difference between the maximum and minimum QT interval.
Abbreviations: bpm, beat per minute; JTc, corrected JT interval; ms, millisecond; QTc, corrected QT interval; QTmax, maximum QT; QTmin, minimum QT; Tp‐e, T peak and end interval.
