The aim was to develop a fully automatic QT interval measurement algorithm for the 2006 PhysioNet/Computers in Cardiology Challenge. The algorithm determined the Q onset and T offset points from the average beat in each lead. The QT interval measurement was calculated from the median Q onset and T offset points. Manual measurements were also made. The mean (sd) difference between automatic and reference measurements was -49 (38) ms and between manual and reference measurements was -6 (48) ms.
