Nuis, et al. examined whether transcatheter aortic valve implantation (TAVI) in patients suffering from severe aortic stenosis led to changes in corrected QT dispersion (cQTD), previously used to predict arrhythmic risk. Dogan, et al. proposed that a different marker, transmural dispersion of repolariza- tion (TDR), has better accuracy in risk prediction.展开更多
