【摘要】：近30年以來,我國經(jīng)濟(jì)發(fā)展迅速,人民生活水平得到極大的改善并開始逐步進(jìn)入小康階段。隨著生活富裕起來廣大人民的生活節(jié)奏被加快,生活方式也與以往相差很大,其中包括生活規(guī)律、飲食規(guī)律、心理狀態(tài)等,然而這些改變導(dǎo)致了我國心臟類疾病的患病率和死亡率迅速上升。在經(jīng)濟(jì)快速發(fā)展的同時我國人口結(jié)構(gòu)逐漸趨于老齡化,老人作為心臟類疾病的高發(fā)人群則進(jìn)一步提高了心臟類疾病的發(fā)病率。同時作為青壯年面對日益增強(qiáng)的工作負(fù)擔(dān)與生活壓力,因心臟猝死的概率也呈上升化趨勢。以上這些都對人民的生命健康產(chǎn)生了極大的威脅,也讓家人甚至整個社會承擔(dān)著巨大的壓力。心電信號作為人體生物電信號的一種,它包含了大量可以體現(xiàn)心血管健康狀態(tài)的生理及病理信息,同時心電信號也能夠及時反映人體心臟的健康狀況。通過對心電信號的處理、分析能夠提前發(fā)現(xiàn)心臟類疾病的發(fā)病征兆,對心臟類疾病的防治及預(yù)防突發(fā)性心臟猝死具有積極意義。為了能夠高效、快速的采集、分析心電信號,本文在基于可穿戴心電監(jiān)護(hù)系統(tǒng)這一實(shí)驗(yàn)室課題的基礎(chǔ)上,開發(fā)了該系統(tǒng)的終端軟件部分并對采集到終端設(shè)備上的心電數(shù)據(jù)進(jìn)行深入分析與研究。相較于一般心電監(jiān)護(hù)系統(tǒng)的終端設(shè)計,本文開發(fā)的終端軟件進(jìn)行了大量的創(chuàng)新性優(yōu)化與擴(kuò)展,心電終端包括PC端心電軟件與移動端心電APP,通過兩者相結(jié)合的方式增加了系統(tǒng)適用于不同使用環(huán)境的可能性。PC端軟件采用具有優(yōu)良跨平臺特性的Qt應(yīng)用架構(gòu)進(jìn)行編寫,主要負(fù)責(zé)心電信息的接收、存儲和分析。移動端心電APP在PC端軟件的功能基礎(chǔ)上結(jié)合自身強(qiáng)大的社交特性,增加了數(shù)據(jù)的第三方分享功能。在數(shù)據(jù)分析模塊,本文首先對心電信號的消噪算法進(jìn)行研究,在此基礎(chǔ)上應(yīng)用曲線的波峰波谷查找算法對心電波形的QRS波進(jìn)行識別提取。最后將生物科學(xué)、計算機(jī)科學(xué)及其他知識進(jìn)行結(jié)合,完成心電終端的心電圖顯示及心電的自動化診斷、智能化分析目標(biāo)。測試結(jié)果表明,本文研究的心電終端系統(tǒng)能夠有效的接收心電數(shù)據(jù),并進(jìn)行數(shù)據(jù)分析,實(shí)現(xiàn)了心電終端智能化目標(biāo)。最終為用戶提供了合理的、具有針對性的健康生活提議。目前,該套系統(tǒng)已經(jīng)完成初步的測試,相信在一些細(xì)節(jié)被不斷的優(yōu)化后,系統(tǒng)將很快能夠投入使用,實(shí)現(xiàn)最終的產(chǎn)品化目標(biāo)并帶來一定的社會及經(jīng)濟(jì)效益。
[Abstract]:In the past 30 years, China's economy has developed rapidly, the people's living standards have been greatly improved, and they have gradually entered the stage of well-off life. With the prosperity of life, the pace of life of the vast number of people has been accelerated, and the way of life is also very different from the past. These changes, however, have led to a rapid rise in the prevalence and mortality of heart diseases in China. With the rapid development of the economy, the population structure of our country is gradually aging. The elderly, as a high risk group of heart diseases, have further increased the incidence of heart diseases. As young adults, they are faced with increasing burden of work and pressure of life. The probability of sudden cardiac death is also on the rise. All of these have posed a great threat to the life and health of the people, and caused great pressure on the family and even the whole society. The ECG signal is one of the bioelectrical signals of the human body. It contains a large number of physiological and pathological information that can reflect the state of cardiovascular health, and ECG signals can also reflect the health of the human heart in time. Analysis can detect the symptoms of heart disease in advance, and has positive significance for the prevention and treatment of heart disease and the prevention of sudden cardiac sudden death. This paper is based on the wearable ECG monitoring system, which is a laboratory project. The terminal software of the system is developed, and the ECG data collected on the terminal equipment are analyzed and studied in depth. The terminal software developed in this paper is innovatively optimized and extended. ECG terminal includes PC end ECG software and mobile terminal ECG app. By combining the two methods, it increases the possibility that the system is suitable for different use environments. PC terminal software is written with QT application architecture with excellent cross-platform characteristics. Mainly responsible for receiving, storing and analyzing ECG information. Mobile ECG APP combines its powerful social characteristics with the function of PC software, and increases the function of data sharing by third party. In this paper, the de-noising algorithm of ECG signal is studied firstly, and then the QRS wave of ECG waveform is identified and extracted by using the algorithm of finding the peak and trough of the curve. Finally, the biological science, computer science and other knowledge are combined. The ECG display of ECG terminal and the automatic diagnosis of ECG are completed. The test results show that the ECG terminal system studied in this paper can receive and analyze the ECG data effectively. It has achieved the goal of intelligent ECG terminal. Finally, it has provided users with reasonable and targeted healthy life proposals. At present, the system has completed preliminary tests, and it is believed that after some details have been continuously optimized, The system will soon be put into use to achieve the final goal of production and bring certain social and economic benefits.
