心电监测、传输和全自动分析系统 ECG monitoring, transmission and automatic analysis system

本发明涉及一种心电监测、传输和全自动分析系统及其方法,更具体地涉及一种适用于佩带的超小型心脏保护系统,及实施该系统的方法。 The present invention relates to an ECG monitoring, automatic transmission and analysis systems and methods, and more particularly, to a subminiature suitable for wearing heart protection system, method and implementing the system.

世界上有各式各样的病魔杀手威胁着人类生存。 There are a wide range of disease killer threatens the survival of mankind in the world. 其中心血管病魔,就是穷凶极恶的第一杀手。 Where cardiovascular disease is the number one killer of atrocious.

世界卫生组织(WHO)于1992年4月7日公布:世界上每年有1200万人死于心血管病,占人类死亡人数的1/4。 World Health Organization (WHO) on April 7, 1992 announced: the world's 12 million people die of cardiovascular disease, accounting for a quarter of the human deaths annually. WHO称心血管病为“世界公众健康的头号敌人”,并将这一天一世界卫生日的主题定为心脏健康,预防心血管病。 Heart disease WHO as "the world's public health enemy number one" and the theme for World Health Day Tianyi as heart health, the prevention of cardiovascular disease. 口号是:“心搏-健康的节律”。 Slogan is: "heartbeat - healthy rhythm."

我国的有关资料表明,我国每年因心血管病丧生的人数占总死亡人数的50%以上。 Our data indicate that the annual number of deaths due to cardiovascular disease in more than 50% of the total deaths. 中国医学科学院的最新公布的数字是,每年我国冠心病患者为9000万人,其中有300万人死于该病的“心肌梗塞”或“心脏性猝死”。 The latest figures released by the Chinese Academy of Medical Sciences is the country every year for 90 million people with coronary heart disease, which has 300 million people died of the disease, "myocardial infarction" or "sudden cardiac death."

面对人类第一杀手,在科学昌盛的今天尤其是当今治疗心血管病药的发明处于爆炸时代,通常很少有救不活的心血管病人。 Faced with the first human killer, in science, especially in today's prosperity today the treatment of cardiovascular disease in the explosion of drug invention, there are few cardiovascular patients usually can not be saved alive. 而心电图(ECG)则是早已为国际公认的诊断心脏病,尤其是冠心病的重要指标之一。 The electrocardiogram (ECG) is already internationally recognized for diagnosis of heart disease, one of the important indicators, particularly coronary heart disease.

心血管病人的死亡常常缘于被误诊,因为病人在早期有冠状动脉缺血时发生胸闷,心前区不适或心绞痛时的心电图未被及时记录下来,医生难给病人戴“冠心病”的帽子,无预防的准备。 Deaths due to cardiovascular patients are often misdiagnosed because the patient has chest occurs in early coronary ischemia, angina precordial discomfort or electrocardiographic not timely recorded, doctors give patients wearing hard "coronary heart disease" hat No preventive preparation. 另一个原因常常是在发病时,病人在医院以外的地方,不可能及时赶到医院,仅仅向医生口述病情,医生还难以给出准确的处置方法。 Another reason is often at the onset, the patient places outside the hospital, can not get to the hospital, only to doctors oral disease, doctors also difficult to give an accurate method of disposal.

已有的心电图机体积大,不便于携带,安置电极多达10个之多,操作复杂。 Existing ECG machine bulky, not easy to carry, up to 10 electrodes placed much complicated to operate. 而早期冠心病患者心律失常和ST-T改变多是短暂的,数分钟而已。 The early coronary artery disease in patients with arrhythmia and ST-T changes are mostly short, just a few minutes. 用普通心电图机捕捉一过性的的心律失常或PR-QRS-ST-T改变是很难做到的。 ECG machine with ordinary capture transient arrhythmias or PR-QRS-ST-T changes are difficult to achieve.

已有的动态心电图机(Holter)虽然能存贮24小时心电信号,但记录器体积大、较重,价格昂贵,无法作为个人保健用品,只能作为医院诊断工具。 Existing dynamic ECG (Holter), although capable of storing 24 hours of ECG, but the record is bulky, heavy, expensive, can not be used as personal care products, only diagnostic tool as a hospital. 病人偶尔佩带24小时,也未必能捕捉到发病时的信号,因为早期冠心病患者的心律失常或PR-QRS-ST-T改变并非每天都会发生。 Patients occasionally wear 24 hours, it may not be able to capture the signal onset, as arrhythmias or PR-QRS-ST-T changes in patients with early coronary heart disease is not an everyday occurrence.

近年来,人们也不断地开发出一些能够随身携带的小型心电监护器,有的体积如32开纸大小,但或无存贮功能或无诊断报警功能,更非智能化,只能在液晶显示器上显示心电图而已,在功能远远达不到实际应用的要求。 In recent years, it has also been able to develop some small portable ECG device, some 32 open volume such as paper size, but with or without storage function or diagnostic alarm function, more non-intelligent, only in liquid crystal ECG on the display only, the function is far less than the actual application requirements. 非医务工作者,不懂心电图的人是不会根据监护器的测试结果了解自己的心脏情况的。 Non-medical workers, who do not understand the ECG is not aware of their heart condition monitoring device according to the test results. 更无法不去医院就将心电信号传送给不同医院的医生进行会诊。 But can not go to the hospital ECG will be sent to different doctors for consultation.

有的便携式心电图机只能对心动过速或心动过缓报警,而不能对波形变化报警。 Some portable ECG machine only for tachycardia or bradycardia alarm, but not alarm on the waveform changes.

在实际的临床现象中,心电图异常不仅仅是心率异常,还有PR-QRS-ST-T改变,千变万化,所对应的心脏病病名也截然不同。 In actual clinical phenomenon, not just abnormal electrocardiogram abnormal heart rhythms, as well as PR-QRS-ST-T changes in the ever-changing, heart disease name corresponding to totally different. 因此必须使机器智能化,即使如此还要依靠医生的确认。 Therefore, the machine must be intelligent, even so must rely on the doctor's confirmation. 不同心脏病以及同一心脏病的不同心电图表现应给药物也截然不同。 Different ECG heart disease and various heart diseases should be given the same drugs are also different. 所以这类发明应科学认真对待。 So this kind of scientific invention should be taken seriously. 但目前有一些心电监护仪器,甚至冠以全自动心脏监护急救仪的名称,却是仅凭心率是否大于180次/分或小于50次/分,并无心电图显示的情况下就报警或给病人进行电起搏,并“自动”给病人弹出药盒。 But there are some ECG monitoring equipment, and even dubbed automatic emergency cardiac care instrument name, but it is the case of the heart rate alone is greater than 180 beats / min or less than 50 beats / min, no electrocardiogram displayed on an alarm or to patient pacing and "automatic" pop-up kits to patients. 这是极其危险的,甚至可能使病人致死。 This is extremely dangerous and may even patient death.

心电图平板运动实验或踏车心电图实验或潘生丁心电实验乃是采用诱发方式使病态心电图暴露出来的方法。 ECG treadmill exercise test or treadmill test or electrocardiogram ECG test dipyridamole-induced manner but using ECG exposed morbid way. 这对病人有一定的危险性。 This patient has a certain degree of risk. 较重病人属禁忌者。 Heavier patient who is contraindicated.

有的便携式心电图机虽然小但它的电极位置不符合国际公认的使三个电极的设置范围(两个探测电极,一个参考电极)应大于心脏范围的规定,或者有的便携式心电图机仅用两个电极,与国际公认的心电导联标准完全不符。 Although some small portable ECG electrode position but it does not comply with internationally recognized set range of the three electrodes (two detection electrodes, a reference electrode) should be greater than the specified range of the heart, or some portable ECG machine just two electrodes, and the internationally recognized standard ECG is completely incompatible. 这样描记出的心电图与国际公认的心电图中相同导联引导的图形不一致,诊断当然也就是错误的。 Such an ECG tracings and internationally recognized lead electrocardiogram same inconsistencies associated graphical boot, diagnostic course, is wrong.

本发明的目的是提供一种心电监测、传输和全自动分析系统及其方法,它使佩带本发明的超小型心脏保护仪器的患者,能够随时通过个人佩戴装置记录和存储心电图(ECG),使得患者随时捕捉异常心电信号成为可能。 Object of the present invention is to provide an ECG monitoring, automatic transmission and analysis system and method, which allows the wearer subminiature cardioprotective apparatus of the present invention, a patient, can be worn at any time by a personal storage device for recording and electrocardiogram (ECG), allows patients to capture abnormal ECG possible. 该装置还对心电信号自动地进行实时分析,初步判断佩带者的心电图是否正常,为患者提供需否就医的初步建议。 The device also automatically performs real-time ECG analysis, preliminary judgment wearer's ECG is normal, if they need medical treatment to provide preliminary recommendations for patients.

本发明的目的进一步在于,提供一种智能化的佩带式超小型心脏保护系统及其方法,其中由个人佩带装置所采集和存储的心电信号,能够通过红外线传输到心电图自动分析装置,自动地得到分析,除了打印出心电图之外,还能够提供出无专业知识的普通人也能看懂的病情分析报告。 The present invention further to provide an intelligent wearable subminiature heart protection system and method in which the individual wearing the ECG acquisition and storage device, capable of infrared transmission to automatic analysis of ECG device automatically be analyzed, in addition to print out the ECG, but also be able to provide the expertise without ordinary people can understand the condition of the analysis report.

本发明的目的还在于,提供一种佩带式超小型心脏保护系统及其方法,它能够通过有线或无线电话通道、寻呼机网络等通讯网络,将个人佩带装置所采集和存储的心电信号传送到远程的(比如医院的)心电分析终端,从而实现患者与医生、医生与医生之间的远程心电图传送,最大限度地为患者提供及时的监护与治疗。 The purpose of this invention is to provide an ultra-compact wearable cardiac protection system and method that can channel through a wired or wireless telephone, pager networks and other communications networks, personal wearable device acquisition and storage of ECG transmitted to remote (such as hospitals) ECG analysis terminal, enabling remote ECG transfer patients and doctors, between doctors and physicians to maximize patient care and provide timely treatment.

参见图9,示出了有关“输入病人信息及文件管理”(S200)子程序的流程。 Referring to Figure 9, there is shown the relevant "input patient information and file management" (S200) subroutine process. 在进入这子菜单(S201)之后,选择项有:(1)输入新病人信息(S202)计算机自动排列病人序号,每输入一个新病人,序号自动加1。 In entering this submenu (S201) after the selections are: (1) Enter the new patient information (S202) computer automatically arranges patient number, enter a new patient each, plus a number automatically. 自动显示当前时间、日期、在此步骤输入患者姓名、性别和年龄。 Automatically displays the current time, date, in this step to enter patient name, gender and age.

(2)回顾老病人信息(S203)这里屏幕出现“OLD”,提示输入已有的病人序号,如输入正确,则屏蔽上显示该病人的姓名、性别、年龄、病例建立的时间等信息;如输入的病号不存在,屏幕上提示“NEW”,表示需重新输入序号。 (2) Review of old patient information (S203) here appears "OLD", has been prompted to enter the serial number of patients, such as the input is correct, then the shield displays the patient's name, sex, age, time and other information established case; if Enter the patient does not exist, the screen prompts "NEW", said the need to re-enter the serial number.

(3)就病人信息资料进行软盘备份(S204)这里屏幕提示输入需要备份的病人信息的起、止序号,以完成备份操作。 (3) patient information on a floppy disk backup (S204) from the patient information screen prompts to enter here to be backed up, only the serial number to complete the backup operation.

(4)将病人信息资料从软盘恢复到硬盘中(S205)(5)格式化新盘(S206)一般在用一张软盘进行备份时都需先经过这一步;(6)返回主菜单(S207)图10示出对ECG信号进行处理的主程序。 (4) the patient recover information from a floppy disk to your hard drive (S205) (5) to format the new disk (S206) is generally used when a floppy disk backups are required to go through this step; (6) Return to the main menu (S207 ) of Figure 10 shows the main routine for processing the ECG signal. 程序从步骤S400开始,经过变量初始化(S401)和取比如6秒ECG进行自学习(S402)以学习受试者的正常窦性心律之后,进入ECG信号预处理步骤(S403)。 Procedure starts from step S400, after the variable initialization (S401) and taking for example 6 seconds ECG self-learning (S402) to learn the subject normal sinus rhythm, the ECG signal into the pre-treatment step (S403). 在此步骤中,利用公式[H(ejω)[=-cosnω+ 2cos(n-1)ω+5cos(n-2)ω+2]/8y(n)=[-x(n)+2x(n-1)+5x(n-2)+4x(n-3)+5x(n-4)+2x(n-5)-x(n-6)]/16其中设-3dB点为28Hz,-20dB阻带为47-53Hz;fs=200Hz,即低通和50Hz带阻合二为一,对心电信号进行滤波和基线校准,使基线拉直,消除50Hz工频干扰和噪声。 In this step, the use of the formula [H (ejω) [= - cosnω + 2cos (n-1) ω + 5cos (n-2) ω + 2] / 8y (n) = [- x (n) + 2x ( n-1) + 5x (n-2) + 4x (n-3) + 5x (n-4) + 2x (n-5) -x (n-6)] / 16 wherein the set point is -3dB 28Hz, -20dB stop band is 47-53Hz; fs = 200Hz, namely 50Hz low-pass and band-stop into one of the ECG signal filtering and baseline calibration, so the baseline straightened, eliminate 50Hz frequency interference and noise.

然后程序进到后续对ECG信号各特征的提取的步骤,即顺序进入QRS波群检测(S404)、P波检测(S405)、ST段、T波分析(S406)的步骤,以便得到最终的分析参数的结果。 The program then proceeds to a step subsequent to the step of extracting features of each ECG signal, i.e. the sequence into the QRS complex detection (S404), P-wave is detected (S405), ST segment, T wave analysis (S406) so as to obtain the final analysis outcome parameters.

图11示出QRs波群的检测步骤(S404)的子程序,其公式是:y(n)=|△1+△2+△3+△4|/4△k=x(n+k)-x(nk) k=1,2,3,4|H(ej&omega;)|=8sin52&omega;&CenterDot;cos&omega;&CenterDot;cos&omega;2]]>首先在步骤S4041检测闽值计算并使计数器清零。 Figure 11 shows a group of QRs wave detection step (S404) subroutine, the formula is: y (n) = | △ 1 + △ 2 + △ 3 + △ 4 | / 4 △ k = x (n + k) -x (nk) k = 1,2,3,4 | H (ej & omega;) | = 8sin52 & omega; & CenterDot; cos & omega; & CenterDot; cos & omega; 2]]> First detection threshold is calculated and the counter is cleared in step S4041. 进入步骤S4042,判断是否有R波检出。 Proceeds to step S4042, determines whether there are any R-wave detection. 在此,首先对ECG信号进行求导,然后形成阈值,即把6秒ECG信号分为11段,找出每段的最大值进行平均,得到一个平均值ave,以每段的最大值与该ave值进行比较,较之大者为有QRS波群,较之小者则为无QRS波群。 Here, the first derivative of the ECG signal, then the threshold value is formed, i.e., the 6 seconds of the ECG signal is divided into 11 segments, each segment to find the maximum averaged to obtain an average value ave, the maximum value of each segment ave value, as there is greater than the QRS complex, compared to small ones, compared with no QRS complex. 将有QRS波群的段的最大值作平均,得到QRS波群的平均差分值th;分别以th值的7/16和3/16作为检测QRS波群的两个闽值th-b和th-r。 Will have a maximum period of QRS complex for average, get the QRS mean difference scores th; respectively 7/16 and 3/16 th value of the QRS complex as a detection threshold of two th-b and th -r. 如果在步骤S4042判断为否,即未检测出R波,程序进到步骤S4043,使计数器加1,差分值与阂值比较然后返回步骤S4042,再进行R波检出判断。 If the judgment is NO, i.e., R-wave is not detected, the program proceeds to step S4043, the counter plus one, comparing the difference value with the thresholds then returns to step S4042, then the R-wave detection judgment. In step S4042 如果在此步骤判断为是,即有R波检出,程序前进到步骤S4044,寻找一阶与二阶差分最大值,使阈值更新。 If this step is determined to be, that is R-wave detection, the program proceeds to step S4044, the first-order and second-order differential to find the maximum value, so that the threshold value is updated. 在此用导数的绝对值检测QRS波群。 The absolute value of the QRS complex is detected in this use derivatives. 当连续2点导数大于闷值时。 When continuous 2:00 derivative values greater than stuffy. 判定为一个新的QRS波群出现,用平均RR问期的5/12作为分界点,前段采用th-b后段采用th-r。 Determining a new QRS complex appears to ask the average period of 5/12 RR as the demarcation point, using the preceding paragraph th-b With th-r.

每检测到一个QRS波群都有条件地更新阈值。 Each detected QRS complex has a threshold condition to update. th-r(new)=th-r(old)&CenterDot;34+aym/16]]>th-r(new)=th-r(old)&CenterDot;34+aym/8]]>aym为QRS波群检测点前后140msmw的最大值。 th-r (new) = th-r (old) & CenterDot; 34 + aym / 16]]> th-r (new) = th-r (old) & CenterDot; 34 + aym / 8]]> aym for QRS wave maximum detection point group of around 140msmw.

更新条件为(aym>th-b)且[(aym<3th-b)或(连续4次未更新)]。 Update conditions (aym> th-b) and [(aym <3th-b), or (4 consecutive times is not updated)]. 然后从S波向后屏蔽260ms继续搜索下一个QRS波群,并且计算RR间期。 S wave back then shielded from 260ms to continue searching for the next QRS complex, and calculate the RR interval.

接下来,程序前进到步骤由S4045,进行Q波起点的定位。 Next, the routine proceeds to the step S4045, the starting point of the Q wave positioning. 在这里aym/9作为Q波起动的定位阈值,下限为4。 Here aym / 9 as a Q-wave starting position threshold, the lower limit is 4.

从每个QRS波群的检测点退80ms,向后搜索Q波起点,直到连续2点导数绝对值均大于阈值。 From each QRS detection point back 80ms, search backwards Q-wave starting until 2:00 continuous derivative absolute value greater than a threshold value. 程序在步骤S4046进行QRS波群终点定位。 QRS complex program end position at step S4046. 在这里采用二阶导数法,其步骤是:(1)对ECG求二阶导数;(2)用求th同样的方法求二阶导数的最大值ayd,取ayd/8作为定位QRS波群终点的阈值th-s,如波形较大(aym>3th-b),则取ayd/10作为th-s,下限为3。 Here the use of second derivative method, the steps are: (1) for the second derivative ECG; (2) by seeking the same way th second derivative maximum ayd, take ayd / 8 as the end of the QRS complex positioning threshold th-s, such as a wave larger (aym> 3th-b), then take ayd / 10 as th-s, the lower limit is 3.

(3)从QRS波群检测点向后跳130ms。 (3) jump from 130ms QRS complex detection point backwards.

(4)从后向前搜索,在100ms内,利用后续3点二阶导致的绝对值大于th-s来定位QRS波群终点。 (4) search forward from within 100ms, the use of the absolute value of the follow-up 3-point lead is greater than the second-order th-s to locate the end of the QRS complex.

(5)求QRS波群的宽度。 (5) Find the width of the QRS complex.

然后,程序前进到步骤S4047和S4048,对QRS波群主极性和噪声进行判别。 Then, the program proceeds to step S4047 and S4048, on the main QRS complex polarity and noise discrimination.

其中,对于QRS波群主极性的判别(S4047)是如此完成的:(1)在QRS波群起点和终点之间以Q波起点为参考点找出幅度最大值的位置;(2)幅度最大值处幅度值与Q波起点处的幅度值相比较,前者大于后者则极性为正;反之,极性为负。 Among them, for the QRS main polar discrimination (S4047) is thus completed: (1) between the start and end of the QRS complex with Q-wave starting point as a reference point to identify the magnitude of the maximum position; (2) the magnitude of at the maximum amplitude value and the amplitude value at the beginning of Q-wave compared to the former than the latter polarity is positive; the other hand, the polarity is negative. 噪声的判别则包括:如果QRS波群起点和终点幅值之差的绝对值大于QRS峰值的一半,则认为此拍为噪声,不进行心律失常的分析。 Discriminating noise include: if the absolute value of the difference between the start and end of the QRS complex amplitude greater than half of the QRS peak, this shot is considered as noise, do not analyze arrhythmia.

程序中用于P波检测的步骤S405(见图10)是采用面积法来完成的。 Program for the P-wave detection step S405 (see Figure 10) is accomplished using the area method. 其计算公式为:ss(k-1)=|x(i-1)-x(i-1-1)|ss(k)=|x(i+1+1)-x(i+2+1)|s=ss(k-1)+ss(k)+s The formula is: ss (k-1) = | x (i-1) -x (i-1-1) | ss (k) = | x (i + 1 + 1) -x (i + 2 + 1) | s = ss (k-1) + ss (k) + s

k=k+2当P波面积S大于阈值时,作为一个P波待定对象,面积最大处即为P波。 k = k + 2 when the P-wave area S is greater than a threshold value, determined as a P-wave object, is the largest area of the P wave.

图10中所示的T波以及ST段分析的步骤(S406)则如此进行,即:对于T波峰点,确定在QRS波终点到T波终点之间幅度最大值处;而T波终点则为:QT=0.391g(RR+0.07)。 T-wave and the ST segment illustrated in FIG analysis step 10 (S406) is carried out so that: for T peak point, determines the maximum amplitude of the QRS complex to the end of the T-wave between the end; and T wave end point was : QT = 0.391g (RR + 0.07).

至于ST段终点的计算,首先假设ST为直线和抛物线:f1=a1x+b1f2=a2x2+b2+c2分别用直线和抛物线拟合ST段和ST终点到T波峰点的曲线,取误差最小者为最后结果,误差用最小平方误差,拟合点从Se到Tp依次选取。 As for the calculation of ST segment endpoints, first assume a linear and parabolic ST: f1 = a1x + b1f2 = a2x2 + b2 + c2 respectively linear and parabolic fitting end to the ST segment and ST T peak point of the curve, take the smallest error is the final results, the error with the least square error fitting point sequentially selected from Se to Tp.

图12示出了显示心律失常结果(S500)的子程序。 Figure 12 shows a display arrhythmias result (S500) subroutine. 在变量初始化(S501)之后,在步骤S502和S503,读出ECG处理信号的参数和病人信息,对参数值进行平均计算,以排除偶发的意外因素影响。 The variable is initialized (S501), in step S502 and S503, readout parameters and patient information ECG signal processing, parameter values on average, to exclude the impact of unexpected factors sporadic. 在步骤S504对所计算的参数值进行心律失常类型的判别。 S504 of parameter values calculated arrhythmia type determined in step. 判别流程参见图13示出的“病类判别例程”。 Discrimination See Figure 13 shows the flow of "illness routine discrimination." 其判据是:心律失常判据1.
