| Abstract: | This paper addressed the application of wavelet to the measurement of QT dispersion and presented a new method using multi thresholds to determinate the end point of T wave. The results geined by computer and human were compared. We also suggested that QT dispersion be defined as the SD of 12 QT intervals. |
