| 摘 要： | 目的 改进用于心肌缺血无创检测的运动心电信号特征分析方法。方法研制一套改进的运动心电信号检测系统，提出单位时间ＳＴ段面积（ＳＴＡ）和ＳＴＡ与相关心率（ＳＴＡ／ＨＲ）的斜率作为新特征参数的计算方法，同时还提出了减少运动信号采集中干扰噪声混入的措施。结果 临床运动试验中采集到的１４例运动心电信号数据特征所进行的分析结果，验证了这些新参数计算的有效性头痛的计算结果不仅计算基本一致，而且提高了运动心电信号

| Abstract: | Objective To improve the exercise ECG analysis for non invasively detection of myocardial ischemia. Method The newly developed measuring system of exercise ECG defines ST segment area and STA/HR slope as the new characteristic parameters,thus can sensitively detect myocardial ischemia. Some methods were proposed to reduce noise and artifacts for effective sampling of exercise ECG. Result 14 exercise ECG records were sampled and analyzed in clinical exercise test.It was found that the new parameters are very effective and sensitive to myocardial ischemia.The results show that the method is reliable and stable. Conclusion The method improves one of the evaluating indexes of exercise ECG analysis.It is quite promising for clinical application in future. |
