Method and apparatus for determining T-wave marker points during QT dispersion analysis

摘要

A method and apparatus for analyzing QT dispersions in ECG lead signals, comprising acquiring a plurality of ECG lead signals, filtering said signals to remove noise without distorting the T-wave morphology, determining critical T-wave marker points, and calculating QT dispersion and their heart rate corrected values from the determined markers. The apparatus comprises a processor programmed to perform these functions.
