QT and QTc dispersion in patients with impaired left ventricular systolic function and matched controls with preserved left ventricular systolic function

  • Values are mean (SEM) unless otherwise stated; χ2analysis except: Student’s t test;*analysis of variance.

  • Ad.QT dispersion, “lead adjusted” QT dispersion; Ad.QTc dispersion, “lead adjusted” QTc dispersion; MI, myocardial infarction; QTc dispersion, QT dispersion corrected for heart rate using Bazett’s formula; SD-QT interval, standard deviation of the QT interval; SD-QTc interval, standard deviation of the rate corrected QT interval.
