Nowadays, automatic recognition algorithm
is being frequently utilized to extract the information concerning cardiac
abnormalities. In this study, a fully automatic novel method based on the continuous
wavelet transform (CWT) was developed for QT intervals in various ECG signals.
Especially, the determination of T-wave end is the paramount problem to be
solved.The developed method was performed to find the beginning of QRS
complexes and the end of T-wave. The proposed algorithm was tested on
MIT-BIH-NSR database given by QT database, then, it yielded the scores 15.17
milliseconds and root-mean-square error of 17.19 milliseconds at silver
standard, 19.22 milliseconds and 20.22 milliseconds at gold standard,
respectively. In conclusion, the proposed algorithm is a fully automatic method
to attain a high performance in the calculation of QT intervals at various ECG
signals.
