Abstract
The authors discuss feasibility to extract additional information about electrical activity of the heart from the ECG magnitude and phase spectrum. Fifty digitized ECG fragments from the MIT-BIH Arrhythmia Database and PhysioBank ECG repository data were analyzed. It was shown that ECG phase harmonics contains valuable information about the ECG signal that can be used eventually for the development of advanced ECG analysis tools.
摘要
作者们讨论了从心电图幅度和相位谱中提取有关心脏电活动的额外信息的可行性。对来自麻省理工学院-贝斯以色列女执事医疗中心心律失常数据库和生理库心电图存储库数据的50个数字化心电图片段进行了分析。结果表明，心电图相位谐波包含有关心电图信号的有价值信息，这些信息最终可用于开发先进的心电图分析工具。
