摘要
目的:观察基于改进的差分阈值法心脏远程监测记录仪对心电信号特征参数提取以及自动分析的准确率。方法:通过对8957例患者采用改进的差分阈值法确定心电信号波形参数的"心安宝"XAB-M3AG型远程心电监测记录仪检测,分析接受到的心电实时条图。结果:共接收心电实时数据46 967条,其中手动发送9564条,定时发送25 830条,自动发送11 573条,异常者占自动发送的49.5%,其余多为活动中干扰所致。结论:基于改进的差分阈值法的提取算法复杂性较低,精确度较高,有很好的实时性,能够有效地实现心电信号实时监测。
Objective：To observe the effects of real-time and retrospective analyze of cardiac remote monitoring based on differential threshold method.Methods： Xin An Bao＆quot; XAB - M3AG ECG remote monitoring system which based on the differential threshold method of improvement being used to determine the parameters of electro cardio signal was installed in 8957 patients.Results： We had collected all 46967 ECG real-time data, including 9564 manual transmission, 25830 timing transmitting and 11573 automatically transmission. 5728 of automatically transmission was with arrhythmia （49.5%） and the others of automatically transmission was attribute to inference.Conclusion： The results showed that algorithm complexity based on the improved differential threshold method is low, the precision is high and it has a good real-time performance. It realized the real-time monitoring of ECG.
