小波分析用于QT离散度的测量

The Measurement of QT Dispersion Using Wavelet Transformation

讨论小波分析在ＱＴ 离散度测量中的运用，提出了用多阈值来定位Ｔ 波终点的新算法。对计算机测量的结果与手工测量进行了对比，提出采用方差来定义ＱＴ 离散度的设想。

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.
