Based on adaptive line enhancement technique, a new method for detecting

本文提出了一种逐拍检测希氏束信号的新方法。这种方法主要是靠自适应谱线增强技术将希氏束信号从大量不相关噪声(主要是肌电噪声)中提取出来。与此同时还提供了一个逐拍检测希氏束信号的实验系统,包括低噪前置处理电路部分及自适应数字信号处理。应用此系统,得出了一些令人鼓舞的结果。作者进行了7条狗的体表与心内插管希氏束电图对比实验。证明本系统测得的体表希氏束信号与心内插管的波形位置基本一致。研究了心血管药物对希氏束信号的波形及位置的影响。另外,还做了18例人体实验,包括正常11例,心脏疾病的病人7例。正常人在屏气时(减小呼吸的影响),希氏束信号重复出现。而房-室传导阻滞等病人的希氏束信号的位置及形状,与正常人比较均有显著差别。对希氏束信号进行了付里叶变换的功率谱分析,表明大部分的希氏束信号能量在50Hz以内。

onlinear dynamics was used to study the characteristics of the complex dynamic system. Indeed, ECG is important information which reflect the active states of heart. In this paper several methods of nonlinear dynamics for processing heart information were introduced. Selected 24 data files of ECG from MITBIH database and divided these data into four groups. There were normal ECG, pacing ECG, ECG with premature ventricular contraction, and ECG with bundle branch block. Queues of Rwave peaks, RR intervals, area below wave between Rwave peaks and length of wave between Rwave peaks extracted from these electrocardiograms were analyzed with Poincare section, the correlation dimension and correlation entropy. The results showed that (a) Significant different distributions of point set on Poincare section were found between Rwave peaks, RR intervals, area below wave between Rwave peaks and length between Rwave peaks, of normal ECG, pacing ECG, ECG with premature ventricular contraction, and ECG with bundle branch block. (b) The correlation dimensions of queues of Rwave peaks and RR intervals were different between normal ECG and those of other three pathological states. The dimension of ECG with premature ventricular contraction were smaller than that of normal ECG. (c) Correlation entropy of Rwave peaks and RR intervals of normal ECG was higher than that of other three pathological states. The normal heart lost more information than that of other three pathological states. Used the methods of nonlinear dynamics to extract dynamic characteristics from ECG so as to research active states of heart, thus helping doctors for clinical application of early diagnosis of diseases of heart in the future.

非线性动力学是用来研究复杂系统动力学特性的,心脏是最为复杂的动力系统之一。心电图是反应心脏活动状态的重要信息。本文介绍了几种非线性动力学处理心脏信息的方法,利用MIT-BIH数据库中的心电数据,对正常心律、起搏心律、室性失常心律和束支传导阻滞心律中的R波峰、R-R间期、R-R波峰间波形下的面积和R-R波峰间波形曲线长度等序列进行了非线性研究。构造了庞卡莱截面,计算了这些序列的相关维数和相关测度熵。研究结果表明正常心律和异常心律以及这几种异常心律之间,对于庞卡莱截面上点集的分布、相关维数和测度熵是有差异的,这为研究心脏活动状态和进一步临床应用于早期诊断心脏疾病提供帮助

People in medical field have divarication on the genesis of the ectopic pacemaker,parallel heart rhythm,atrial fibrillation,etc,which usually emerge in clinic.This paper analysised the ionic pathways of excitable cellulaes according to the theory of nonlinear dynamic,and performed the simulation on computer that the change of the nonlinear character leading to heart diseases,which caused by the variety of the membrane ionic pathway.Thus it can provide a new method for reference to treat the heart diseases.

对于临床上经常见到的异位起搏点、并行心率、心房纤颤等等心脏疾病的成因,医学界一直存在分歧.从非线性动力学理论的角度出发,对可兴奋细胞的离子通道进行分析,并在计算机上仿真出由于细胞膜上离子通道的变化引起的非线性特性变化而导致心脏病的产生,从而为我们治疗心脏病提出了一种借鉴的方法.
