动态心电的交互信息及分析技术研究

研究发现,动态心电图RR间期序列的交互信息,与随机运动和周期运动的交互信息明显不同,处于两者之间.1 d中不同时段,患单支冠脉病变、多支冠脉病变和糖尿病病人RR间期交互信息的特征与正常健康人存在差异.同样的情况下,病状越严重,相应RR间期的交互信息越大.

Research progress in mutual information of dynamic electrocardiogram

The mutual information of R-R intervals in dynamic electrocardiogram sequences is very different to random motion and period motion.Comparatively,mutual information of R-R intervals is similar to chaotic movement in many ways.Moreover,the mutual information of R-R intervals exhibits different patterns over different periods of a day and different subject groups(single coronary artery disease,multi-coronary artery disease,diabetes mellitus,healthy control).In the same station,the disease is more serious the MI is larger.
