Dispersion of the corrected QT and JT interval in the electrocardiogram of alcoholic patients.
The aim of this study was to analyze the corrected QT interval (QTc), its dispersion (QTcd), and the QT interval index (QTcI) and to compare it with the corrected JT interval (JTc), its dispersion (JTcd), and the JT interval index (JTcI) in long-term alcoholic users, by investigating the ventricular activation until the completion of repolarization. ⋯ Persons who consume various alcoholic beverages excessively and for a long time have significantly higher dispersions of the QTc and JTc, intervals and they have a significantly higher estimation of relative risk for the prolonged QTc interval and higher QTc dispersion than the control group, i.e., higher risk of arrhythmias.
