冠心病频谱心电图与心电图、心电向量图检查的对照分析

摘要

目的：探讨频谱心电图对冠心病诊断的价值。方法：对254例经心电图、心电向量图确诊的冠心病，同步做频谱心电图检查，并作对照分析。结果：两者冠心病诊断符合率66.9％。其中，心电图或心电向量图表现以心室除复极异常为主者符合率91.1％，起搏或传导系统改变为主者符合率45.3％。结论：频谱心电图对心室除复极异常，特别对冠心病和心肌梗死的诊断率高达91.1％，为检测心电信息的一种新方法。%Objective: To explore the significance of examination of spectrum ECG in patients with coronary heart disease (CHD). Methods: Spectrum ECG and ECG、 vectorcardiogram examination were meanwhile executed in 254 patients with coronary heart disease. Results: Diagnose coincidence rate of CHD was 66.9% by spectrum ECG and ECG、 vectorcardiogram examination. Conclusion: Spectrum ECG is a new detect method for electrocardiogram information.
