【摘要】：由于我國人口眾多,加上經(jīng)濟與生活水平的提高,人口老齡化問題加劇,具有較高的發(fā)病率和死亡率的房顫也越來越受到醫(yī)學(xué)界的關(guān)注。為了使房顫的無創(chuàng)電生理治療成為可能,就必須保證房顫檢測和房顫成分提取的精確度。到目前為止,已有的房顫算法研究在檢測準(zhǔn)確率上存在不足。本論文將散射變換與心率變異性分析融合來對房顫進行檢測,主要研究工作如下:1、介紹了一種基于心率變異性分析的房顫檢測,其中包括三個統(tǒng)計學(xué)方法,分別是香農(nóng)熵、相鄰RR間期差值均方根以及轉(zhuǎn)折點比,并對房顫判斷準(zhǔn)則進行介紹;2、散射變換可以獲得有效的信號特征,又可恢復(fù)損失的高頻信息,本文基于散射變換對房顫進行檢測;3、在房顫檢測時選擇性融合散射變換與心率變異性分析,首先基于心率變異性分析對房顫進行檢測,估計其檢測不好的樣本用散射變換的方法進行檢測,將兩者進行融合得到最終的檢測結(jié)果。通過MIT-BIH房顫數(shù)據(jù)庫來評價本方法房顫檢測準(zhǔn)確率,并且與參考方法進行對比,驗證了本方法的可行性。
[Abstract]:Due to the large population of our country, coupled with the improvement of economy and living standards, the problem of population aging is aggravated, and atrial fibrillation with high incidence and mortality has been paid more and more attention by the medical profession. In order to make the noninvasive electrophysiological treatment of atrial fibrillation possible, it is necessary to ensure the accuracy of atrial fibrillation detection and atrial fibrillation component extraction. Up to now, there are some shortcomings in the detection accuracy of the existing Atrial Fibrillation algorithms. In this paper, the fusion of scattering transformation and heart rate variability analysis is used to detect atrial fibrillation. The main research work is as follows: 1. A detection of atrial fibrillation based on heart rate variability analysis is introduced, including three statistical methods, namely, Shennong entropy, mean square root mean square difference of adjacent RR interval and turning point ratio, and the judgment criteria of atrial fibrillation are introduced. 2. Scattering transform can obtain effective signal characteristics and recover the high frequency information of loss. In this paper, AF is detected based on scattering transform. 3, selective fusion scattering transform and heart rate variability analysis are used in AF detection. Firstly, AF is detected based on HRV analysis, and the samples whose detection is not good are detected by scattering transformation method, and the final detection results are obtained by fusion of the two. The accuracy of AF detection was evaluated by MIT-BIH Atrial Fibrillation Database, and the feasibility of this method was verified by comparing it with the reference method.
