摘要
目的:心电散点图在心率变异性分析中的应用效果,探讨提高心率变异性分析准确性的方法。方法:对100例动态心电图数据中的心率变异性心电散点图和频域、时域指标展开分析,对心电散点图指标的特点进行观察。结果:心电散点图用于表达心率变异性的各项指标与时域、频域指标,心电散点图视觉直观性强,能分辨出真实窦性心搏图形与干扰伪差图形,窦性心搏图形具有多态性和个体唯一性。结论:心电散点图可独立用于心率变异性分析。对于记录不良,伪差干扰较多的心电数据,频域、时域分析结果易受其影响,应以散点图的窦性心搏图形作为判断HRV的依据。对于记录质量较好的数据,可根据对散点图形的目测,检验时域、频域分析的准确性。一份高质量的HRV分析报告的标志是散点图、时域、频域三种分析结果中各相关指标高度相关。
Objective：To analyze the application effect of Ecg scatter plot in the analysis of heart rate variability and to explore the accuracy of the heart rate variability analysis method.Methods：To analyze dynamic electrocardiogram（ecg）data scatter diagram and frequency domain,time domain index of 100 cases of heart rate variability in ecg and observe the characteristics of ecg scatterplot index.Results：Ecg scatter diagram is used to express the indicators of heart rate variability with time domain and frequency domain index,and ecg scatter plot has strong visual intuitive,which can distinguish real sinus cardiac graphic and pseudo differential interference graphics,sinus cardiac graphics are polymorphic and individual uniqueness.Conclusion：Ecg scatter plot can be independently used in heart rate variability analysis.For histories,pseudo differential interference more ecg data,frequency domain and time domain analysis results are susceptible to the effects,which should be in a scatterplot sinus cardiac graphics as the basis of judging HRV.For a better quality of recorded data,according to the scatter graphic visual inspection,check up the accuracy of the time domain,frequency domain analysis.A sign of a high quality of HRV analysis report is the highly relevant related indicators of scatter plot diagram,the time domain,and frequency domain.
