Evaluation of an automatic threshold based detector of waveform limits in Holter ECG with the QT database

Abstract:

In this paper we evaluate a single-lead threshold based ECG wave boundaries detector with a QT database developed for validation purposes. We also identify its different sources of error distinguishing those that come from precision errors in boundary location from those that come from morphology misclassification. We obtain 71% of records with correct morphology identification of T wave and variance in boundary location within manual referees variance. The remaining records analyzed correspond to signals with poor SNR at the T wave, or morphology discrepancies between algorithm and experts.
