佩带式超小型心脏保护系统及其方法  Wearable ultra-small heart protection system and method
技术领域 Technical field
本发明涉及智能化电子心脏保护糸统及其方法, 更具体地涉及一 种适用于佩带的超小型心脏保护糸统,及实现该糸统的方法。  The present invention relates to an intelligent electronic heart protection system and a method thereof, and more particularly to an ultra-small heart protection system suitable for wearing, and a method for implementing the system.
背景技术 Background technique
世界上有各式各样的病魔杀手威胁着人类生存。其中心血管病 魔,就是穷凶极恶的第一杀手。  There are a variety of disease killers in the world that threaten human survival. Among them, the cardiovascular disease devil is the worst killer.
世界卫生組织(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。 WHO称心血管病为 "世界公众健康的头号敌人",并^这一天一世界卫生日的主题定为 心脏健康,预昉心血管病。 口号是: "心搏一健康的节律"。  The World Health Organization (WHO) announced on April 7, 1992: 12 million people die of cardiovascular disease each year in the world, accounting for a quarter of human deaths. The World Health Organization calls cardiovascular disease "the number one enemy of public health in the world", and on this day, the theme of World Health Day is heart health, which predicts cardiovascular disease. The slogan is: "Heart beats a healthy rhythm".
我囯的有关資料表明,我国每年因心血管病丧生的人数占总死亡 人数的 50%以上。 中国医学科学院的最新公布的数字是,每年我囯冠 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"。  Relevant data from China indicate that the number of deaths due to cardiovascular disease in China accounts for more than 50% of the total deaths each year. The latest figures released by the Chinese Academy of Medical Sciences are that 90 million people suffer from coronary heart disease each year in China, and 3 million of them die from the disease's "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。 而心电图 (ECG)则是早已为国 ί示公认的诊断心脏病,尤其是冠心病的重要指标 之一 0 Faced with the first killer of human beings, in today's prosperous science, especially today, the invention of medicines for treating cardiovascular diseases is in the era of explosion, and there are usually few rescued cardiovascular patients. The electrocardiogram (ECG) is already showing for the country ί recognized diagnosis of heart disease, especially one important indicator of coronary heart disease 0
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,无预昉的准备。 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。.  Cardiovascular patients die often because they are misdiagnosed, because patients have chest tightness during early coronary ischemia, and the ECG when the precardiac area is uncomfortable or angina is not recorded in time. No preparations. Another reason is often that when the patient is ill, the patient is not in the hospital and it is impossible to rush to the hospital in time. It is difficult for the doctor to give an accurate treatment method just to dictate the illness to the doctor. .
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。 而早期冠心病患者心律失常和 ST— Τ改变多是短暫的,数 分钟而已。 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。■ Existing electrocardiographs are bulky and not easy to carry, as many as 10 electrodes are placed, and the operation is complicated. In patients with early coronary heart disease, arrhythmias and ST-T changes are mostly transient, only a few minutes. Capture transient arrhythmias or PR with an ordinary electrocardiograph — 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 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。病人偶尔保帶 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。  Although existing Holter machines can store 24-hour ECG signals, they are bulky, heavy, and expensive. They cannot be used as personal health products, but can only be used as hospital diagnostic tools. Patients occasionally hold for 24 hours, and may not be able to capture the signal at the time of onset, because arrhythmia or PR-QRS-ST-T changes in early coronary heart disease patients do not occur every day.
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 ^, 有的体积如 32开紙大小,但或无存贮功能或无诊断报譬劝能,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。 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。 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。  In recent years, people have also continuously developed some small ECG monitors that can be carried with them. Some are as large as 32 paper sheets, but they have no storage function or no diagnostic report. The electrocardiogram is displayed on the liquid crystal display, and the function is far from the requirements of practical applications. Non-medical workers, people who do not understand the ECG will not know their heart condition based on the test results of the monitor. It is also impossible to send ECG signals to doctors in different hospitals for consultation without going to the hospital.
有的便携式心电图机只能对心动过速或心动过緩报譬, 而不能对 波形变化报譬。  Some portable electrocardiographs can only report tachycardia or bradycardia, not waveform changes.
在实际的临床现彖中,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。 因此 必须使机器智能化, 即使如此还要依靠医生的确认。 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。 所以这类发明应 科学认真对待。 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譬或给病人进行电起搏, 并"自动"给病 人弹出药盒。 这是极其危险的,甚至可能使病人致死。  In the actual clinical situation, ECG abnormalities are not only abnormal heart rate, but also PR-QRS-ST-T changes, which are ever-changing, and the corresponding heart disease names are also quite different. It is therefore necessary to make the machine intelligent, and even then rely on the doctor's confirmation. Different heart diseases and different ECG performance of the same heart disease should be given different drugs. So such inventions should be taken seriously scientifically. However, there are currently some ECG monitoring devices, even the name of a full-automatic cardiac monitoring first aid device, but it only reports whether the heart rate is greater than 180 beats / min or less than 50 beats / min, and there is no ECG display. Pace the patient electrically and pop the pill box "automatically" for the patient. This is extremely dangerous and can even kill the patient.
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。这对病人有一定的危险性。 较重病人属禁忌者。  The ECG treadmill exercise test or the treadmill ECG test or the Pan Shengding ECG experiment are methods of exposing the pathological ECG using induction. This has certain risks for patients. Heavier patients are 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?示公认的心电导 联标准完全不符。 这样描记出的心电图与囯?示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。  Although some portable electrocardiographs are small, their electrode positions do not comply with internationally recognized regulations that the setting range of three electrodes (two detection electrodes and one reference electrode) should be larger than the heart range, or some portable electrocardiographs only use two Electrodes, with the country? This shows that the accepted ECG standards are completely inconsistent. The electrocardiogram described in this way is inconsistent with the same lead guidance pattern of the nationally recognized ECG, and the diagnosis is of course wrong.

本发明的最佳实施方式 Best Mode of the Invention
如图 1— 3所示, 本发明的心脏保护糸统基本由个人佩带装置 1、 信号传输装置 2和心电图自动分析器 3組成。 参见图 1,本发明的个人 佩带装置 包括由电极 10和心电信号放大器.11組成的心电信号采集 器,由单片机芯片 12构成的智能化分析处理器、蜂鸣器和 /或指示灯 13,以及红外发射器 14。 整个个人佩带装置在外型上做成一个带坠项 链的形式,其中三个电极 10按特定位置形成 项链上,使其自然位置 大致按标准心电 Π导联的结构位置分布, 即使一个探測电极位于右镇 骨中线和第二肋间交点处, 另一探测电极位于左下胸部肋软骨缘之上 方与左锁骨中线交点处, 参考电极则设在右侧肋软骨缘之上方与右侧 锬骨相交点处,参见图 23所示的例子。 这样,使得即使是不懂医学的 人, 能在无需医护人员协助指导的情况下正确寻找导联位置并能准 确安装。本发明心电导联符合囯?示认定的标准 Π导导联这一前提,保 了本发明糸统中所采集的心电图的标准性和正常性。 所得结果与囯 ί示公认的心电学结论有可比性。 当保带这种装置(项链)的患者感到心 脏不适或者在任何需要检测和记录 ECG时,接上佩带在胸前的"项 链,,上的三个电极 10,该装置即可采集电心信号。 这些电极 10可以做 成子母扣的形式,通过简单的压按即可接合; 可利用固态的导电胶来 实现,这样在不记录时病人身上无需受电极禾縛。心电放大器 11将电 极 10所采集的心电信号进行放大, 然后送至单片机 12中进行分析和 处理。当单片机 12判明所采集的心电信号为异常 ECG时,通过向蜂鸣 1% 13发出信号,使之发出例如 "BB"的声音,向佩带者示譬;如果心电 信号正常,则使蜂鸣^ 13发出例如音乐之声。 也可以采用指示灯的形 式, 当判明所采集的心电信号为异常 ECG时,例如点亮红灯进行示 警,而在 ECG正常时,例如点亮绿灯。 As shown in FIGS. 1-3, the cardioprotective system of the present invention basically consists of a personal wearing device 1, a signal transmission device 2, and an automatic electrocardiogram analyzer 3. Referring to FIG. 1, the personal wearing device of the present invention includes an ECG signal collector composed of an electrode 10 and an ECG signal amplifier .11, an intelligent analysis processor composed of a single-chip microcomputer chip 12, a buzzer, and / or an indicator light 13 , As well as the infrared emitter 14. The entire personal wearing device is made in the form of a necklace with a pendant, and three electrodes 10 are formed on the necklace according to a specific position, so that it is in a natural position. It is roughly distributed according to the structure position of the standard ECG lead, even though one detection electrode is located at the intersection of the right midsteel line and the second intercostal space, and the other detection electrode is located above the left lower chest rib cartilage margin and the left clavicle intersection line. The electrode is set at the intersection of the right costal cartilage margin and the right sacrum, see the example shown in FIG. 23. In this way, even people who do not understand medicine can correctly find the lead position and accurately install it without the assistance of medical staff. The premise that the ECG lead of the present invention complies with the standard Π lead that is recognized by the national standard guarantees the standardness and normality of the ECG collected in the system of the present invention. The results obtained are comparable with the nationally recognized ECG conclusions.

图 7— 1和图 7— 2示出个人佩帶装置中单片机对心电信号进行分 析的程序流程图。个人俅戴装置分析程序始于步骤 S001。 在步骤 S002,对计数器 T0、T1进行初始化,在步骤 S003 ,串行输入输出(SIO) 口初始化。 步骤 S004 ,判断是否 PUM (参见图 4中 PUM1端口)输出。 若为是,程序进入步骤 S012 ,进行 PUM输出,^信号送至蜂鸡器,控制 其发出特定声音, 然后到步骤 S013, 切断电源。 若步骤 S004判断为 否,流程前进到步骤 S005,判断是否要将心电信号在心电图自动分析 装置中的读出装置上回放。若是,到步骤 S006回放心电图,将心电信号 传送给心电图自动分析装置,进行计算机分析,再进入步骤 S013 ,切 断电源;若为否,则进行到步骤 S007 ,判断是否为 RAM的串行口自检。 自检的目的是对个人保带装置的硬件连接装置的硬件连接状态进行检 查,比如确定电极连接是否正确和确实。若步驟 S007判定为是,流程 在步骤 S008对 RAM的串行口同时进行自检,然后进到步骤 S013,切 断电源;若为否,流程进到步骤 S009 ,进行 RAM自检。在 RAM自检中, 如果发现电极未接触好或硬件有故障时, 装置中的红灯点亮,或者使 蜂鸣^发出某种约定的声音,提醒用户检查保带装置的连接情况, 重 新进行电极连接和启动。在 RAM自检通过之后,即确定装置的连接及 状态良好以好,进到步骤 S010进行变量的初始化。 然后装置在步骤 S011进行自适应学习,比如利用 6秒钟的时间, 来学习装置保帶者正 常窦性心律,作为后续对心电信号进行分析处理的基础。  Figure 7-1 and Figure 7-2 show the flow chart of the analysis of ECG signals by the single chip microcomputer in the personal wearing device. The personal wearing device analysis program starts at step S001. In step S002, the counters T0 and T1 are initialized. In step S003, the serial input output (SIO) port is initialized. In step S004, it is determined whether PUM (see PUM1 port in FIG. 4) is output. If yes, the program proceeds to step S012, performs PUM output, and sends a ^ signal to the buzzer to control it to make a specific sound, and then proceeds to step S013 to cut off the power. If the determination in step S004 is no, the flow advances to step S005, and it is determined whether the ECG signal is to be played back on a reading device in the automatic electrocardiogram analysis device. If yes, go to step S006 to play back the ECG, and send the ECG signal to the automatic ECG analysis device for computer analysis, and then go to step S013 to cut off the power; if not, go to step S007 to determine whether it is a serial port of the RAM. Check. The purpose of the self-test is to check the hardware connection status of the hardware connection device of the personal belt device, for example, to determine whether the electrode connection is correct and correct. If it is determined as YES in step S007, the flow performs a self-test on the serial port of the RAM at the same time in step S008, and then proceeds to step S013 to cut off the power; if not, the flow proceeds to step S009 to perform a RAM self-test. In the RAM self-test, if it is found that the electrodes are not in good contact or the hardware is faulty, the red light in the device lights up, or the beep sounds a certain sound, reminding the user to check the connection of the holding device, and repeat Electrode connection and start. After the RAM self-test is passed, it is determined that the connection and status of the device is good. Go to step S010 to initialize the variables. Then the device performs adaptive learning in step S011, for example, using 6 seconds to learn the normal sinus rhythm of the device holder, as a basis for subsequent analysis and processing of the ECG signal.
继续参见图 7— 2,在步骤 S014判断 RAM是否已满。若已满,程序 前进到步骤 S015, 显示判别结果置满标志,然后在步骤 S022关断电 源;若未满,程序在步骤 S016进行心电图预处理,然后进行 QRS波群 检测 (S017)、T波检测 (S018)、ST段检测 (S019)、P波检測 (S020)。在步 骤 S022 ,依据前述的"单片机对异常心拍的判揚"的设定值,来判别所 检测出的各项参数是否正常,进而作出对心脏情况的判断,以供蜂鸣器 发出有关正常的或不正常的譬示之声, 或由指示灯作出相应颜色的指 示。然后程序循环到步骤 S014,判断 RAM是否已满。有关对 ECG预处 理、 QRS波群检测、T波检测、ST段的检测,以及 P波检测的子程序,可 参见后续对心电图自动分析装置的计算机处理流程的有关说明。 With continued reference to Figure 7-2, it is determined at step S014 whether the RAM is full. If it is full, the program proceeds to step S015, the determination result is set to full flag, and then the power is turned off in step S022; if it is not full, the program performs ECG preprocessing in step S016, and then performs QRS complex detection (S017), T wave Detection (S018), ST segment detection (S019), P wave detection (S020). In step S022, according to the aforementioned "Single Chip Microprocessor's Judgment of Abnormal Heartbeat", it is determined whether the detected parameters are normal, and then a judgment is made on the condition of the heart for the buzzer to send out information about the normal Or abnormal sound, or the corresponding color is indicated by the indicator light. The program then loops to step S014 to determine whether the RAM is full.

The program starts from step S400, after variable initialization (S401) and taking, for example, 6 seconds ECG for self-learning (S402) to learn one] 2 — After learning the subject's normal sinus rhythm, the ECG signal preprocessing step is entered (S403). In this step, use the formula
| Η(^ω) I =〔一 cosn o+2cos(n—: L)co+5cos(n— 2)ω+2〕/8 | Η (^ ω ) I = 〔一 cosn o + 2cos (n—: L) co + 5cos (n— 2) ω + 2] / 8
y(n) = C— (n) + 2x(n+D + 5x(n-2) + 4x(n— 3)  y (n) = C— (n) + 2x (n + D + 5x (n-2) + 4x (n— 3)
+5x(n-4) +2x(n-5) -x(n-6)Vl6  + 5x (n-4) + 2x (n-5) -x (n-6) Vl6
其中设一 3dB点为 28Hz,一 20dB阻帶为 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。  Among them, a 3dB point is 28Hz, a 20dB stopband is 47-53Hz; fs = 200Hz, that is, the low pass and 50Hz band stop are combined into one, and the ECG signal is filtered and baseline calibrated to straighten the baseline and eliminate 50Hz Power frequency interference and noise.
然后程序进到后续对 ECG信号各特征的提取的步驟, 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。  Then the program proceeds to the subsequent steps of extracting each feature of the ECG signal, that is, sequentially entering the steps of QRS wave group detection (S404), P wave detection (S405), ST segment, and T wave analysis (S406) in order to obtain the final analysis. The result of the parameter.
图 11示出 QRS波群的检测步骤 (S404)的子程序,其公式是: γ(η) = | Δ1+Δ2+Δ3+Δ4 | /4 Figure 11 shows the subroutine of the QRS complex detection step (S404). The formula is: γ (η) = | Δ1 + Δ2 + Δ3 + Δ4 | / 4
首先在步骤 S4041检测阈值计算并使计数 清零。 进入步骤 S4042 ,判断是否有 R波检出。在此,首先对 ECG信号进行求导,然后形 成阔值, 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。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波群的两个阈值 th-b和 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 S.1043 ,使计数器加 1,差分值乌 阈值比较然后返回步骤 S4042,再进行 R波检出判断。 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。在此用导数的绝对值检测 QRS波群。当连续 2 点导数大于阈值时,判定为一个新的 QRS波群出现,用平均 RR间期的 5/12作为分界点,前段采用 th-b后段采用 th_rFirst, in step S4041, the threshold calculation is detected and the count is cleared. The process proceeds to step S4042 to determine whether an R wave is detected. Here, the ECG signal is first differentiated, and then a threshold is formed, that is, the 6-second ECG signal is divided into 11 segments, and the maximum value of each segment is found and averaged to obtain an average value ave. The ave value is compared. The larger one has QRS complexes, and the smaller one has no QRS complexes. The maximum values of the segments with the QRS complex are averaged to obtain the average difference value th of the QRS complex; 7/16 and 3/16 of the th value are used as the two thresholds th-b and th_ r for detecting the QRS complex, respectively. . If the determination is NO in step S4042, that is, no R wave is detected, the program proceeds to step S.1043, increments the counter by 1, compares the difference value with a threshold, and then returns to step S4042, and then performs R wave detection judgment. If it is judged as YES in this step, that is, an R wave is detected, the program proceeds to step S4044 to find the maximum value of the first-order and second-order difference, and the threshold is updated. Here, the absolute value of the derivative is used to detect the QRS complex. When two consecutive points derivative is greater than the threshold value, it is determined that a new occurrence of the QRS complex, the average RR interval of 5/12 as a demarcation point, using the preceding paragraph b th- after use th_ r.
每检测到一个 QRS波群都有条件地更新阔值。  Conditionally updates the threshold for each QRS complex detected.
th— r(neco) =th— r(old) '^- +aym/16 • th— r(neco) =th— r(old) +aym/8 th— r (neco) = th— r (old) '^-+ aym / 16 • th— r (neco) = th— r (old) + aym / 8
aym为 QRS波群检测点前后 140msmw的最大值。  aym is the maximum value of 140msmw before and after the QRS complex detection point.
更新条件为( aym〉th_b)且〔(aym<3th— b)或(连续 4次未更新) 然后从 S波向后屏蔽 260ms继续搜索下一个 QRS波群,并且计算The update conditions are (aym> th_ b ) and [(aym <3th— b ) or (4 consecutive times without updating), and then the S wave is masked back for 260ms to continue searching for the next QRS complex and calculate
RR间期。 RR interval.
接下来,程序前进到步骤由 S4045,进行 Q波起点的定位。在这里 aym/9作为 Q波起动的定位阈值,下限为 4。  Next, the program proceeds to step S4045 to locate the starting point of the Q wave. Here, aym / 9 is used as the positioning threshold for Q wave start, and 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。 程序在步骤 S4046进行 QRS波群终点定 位。 在这里采用二阶导数法,其步骤是:  Step back 80ms from the detection point of each QRS complex, and search backward for the starting point of the Q wave, until the absolute value of the continuous two-point derivative is greater than the threshold. The program locates the end point of the QRS complex in step S4046. Here the second derivative method is used, the steps are:
(1)对 ECG求二阶导数;  (1) Find the second derivative of ECG;
(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。 (2) using the same method seeking th ayd selecting the maximum value of the second derivative, taking ayd / 8 as the threshold value th- s end positioned QRS complex, such as a large waveform (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 !£ 130ms 0 (3) Backward from QRS complex detection point! £ 130ms 0
( 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 from the back to the front, within 100ms, use the absolute value caused by the subsequent 3 points second order to be greater than th-s to locate the QRS complex end point.
(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 steps S4047 and S4048 to discriminate the main polarity and noise of the QRS complex.
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。 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。  Among them, the discrimination of the main polarity of the QRS complex (S4047) is so complete: (1) find the position of the maximum amplitude with the starting point of the Q wave between the start and end of the QRS complex; (2) the amplitude The amplitude value at the maximum value is compared with the amplitude value at the start of the Q wave. The former is greater than the latter and the polarity is positive; otherwise, the polarity is negative. The discrimination of noise includes: if the absolute value of the difference between the amplitude of the start point and the end point of the QRS complex is greater than half of the peak value of the QRS, the beat is considered as noise and no arrhythmia analysis is performed.
程序中用于 P波检测的步骤 S405(见图 9)是采用面积法来完成 的。 其计算公式为:  Step S405 (see Figure 9) for P-wave detection in the program is completed using the area method. The calculation formula is:
ss(k— 1)= |x(i— 1)— (i— 1— 1) I  ss (k— 1) = | x (i— 1) — (i— 1— 1) I
ss(k)= |x(i+l+l)-x(i+2+l) I  ss (k) = x (i + l + l) -x (i + 2 + l) I
s=ss(k— l)-fss(k)+s  s = ss (k— l) -fss (k) + s
— 1Ί — •k = k + 2 — 1Ί — • 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。  When the P-wave area S is greater than the threshold, as a P-wave pending object, the largest area is 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;  The T-wave and ST-segment analysis steps (S406) shown in FIG. 10 are performed as follows: For the T-wave peak point, determine the maximum amplitude between the QRS-wave end and the T-wave end;
而 T波终点则为: QT= 0. 391g(RR- 0. 07)。  The T-wave end point is: QT = 0.391g (RR- 0.07).
至于 ST段终点的计算,首先假设 ST为直线和拋物线:  As for the calculation of the end of the ST segment, first assume that ST is a straight line and a parabola:
f^a!X+b, f2 =a2x2 +b2+c2 f ^ a! X + b, f 2 = a 2 x 2 + b 2 + c 2
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。  The straight line and parabola were used to fit the curve of ST segment and ST end point to the peak of T wave, taking the least error as the final result, using the least square error, and fitting points were selected from Se to Tp in order.
