摘要
寻求心脏病的早期诊断方法是当务之急,高频心电除了具有较宽的通频带和较小信号幅度外,它比常规心电图具有更多的有关心脏活动状态的信息,可以观察到更多有关心脏主要部位病变的细节,能揭示出QRS综合波上某些部位的波形特征,所谓切迹(motch)和转折(slur)。本文重点研究高频心电的分析和识别方法及其技术实现。
High - frequency ECG has more information about the state of cardiac activity to be perceived that what can be seen in a clinical ECG in detail with a broder bandwidth and smaller signal amplitude. It can reveal waveform features called NOTCHes and SLURs in parts of QRS complex. We have studied the analyzing and recognizing method of high-frequency ECG and its realizing technologhy.
