摘要:
在Poincare散点图的基础上,提出了基于RR间期的一阶差分散点图的新型分析方法.一阶差分散点图将RR间期作一阶差分以形成新的序列,再按Poincare方式作图,凸现了RR间期变异的信息,并以特殊区域反映在散点图上,通过图示可以挖掘出更多的心率变异信息,对非偶联的早搏、偶联性质的二联律和三联律早搏能分别显示出特有的图形特征,从而做出比Poincare散点图更好的鉴别.而在分析混合型早搏时,一阶差分散点图鉴别结果更好.
Abstract:
A new approach of plot by first order difference based on RR intervals, which is related to the Poincare plot analysis is proposed. While plotting with the senies of RR intervals by first order difference, it may form some special areas to express information about HRV(heart rate variability). Compared with Poincare plot the first order difference plot is better at time serial difference analysis. It is able to investigate deep information of heart rate variability. It has a sensitivity to find isolated premature beats without bigeminy or trigeminy, and also find atrial or ventricular bigeminy and trigeminy. The results show that this method has a better performance to distinguish premature beats by bigeminy or trigeminy.
