    Abstract

    This paper presents an algorithm for automated QT interval assessment, developed on several databases that provide expert annotations for QRS onset and T offset locations: The PhysioNet QT Database, the CSE Multilead Database, and the PTB Diagnostic ECG Database. The latter was also used for validating the algorithm by taking part in the Computers in Cardiology Challenge 2006. After QRS detection, the QT interval was calculated for each single heart beat of each signal based on a previously developed algorithm. First the QRS onset and T offset were found coarsely for each channel, thereafter exact point detection was applied based on the coarsely found points and finally the results from different channels were combined. We achieved a score of 16.34 when participating in the Computers in Cardiology Challenge 2006, which was the best result of all participants.
