Clinical significance of increased OT dispersion in the 12-lead standard ECG for arrhythmia risk prediction in dilated cardiomyopathy.


QT dispersion was determined from the 12-lead standard ECGs from 107 patients with idiopathic dilated cardiomyopathy (IDG) and compared to QT dispersion measurements in 100 healthy age and sex matched controls. QT dispersion, rate corrected QT dispersion and adjusted QTc dispersion were significantly greater in patients with IDC compared to controls. During… (More)
