The embodiments of the present application will be further described with reference to the accompanying drawings. Fig. 1 shows a schematic structural diagram of an apparatus 100 for electrocardiographic monitoring according to an embodiment of the present application. Referring to fig. 1, an apparatus for electrocardiographic monitoring according to an embodiment of the present application includes: the electrocardio sensing unit 1, the monitoring unit 2 and the processing unit 3. Wherein:
the electrocardio sensing unit 1 is used for acquiring a first digital electrocardiosignal of a patient in a treatment state.
And the monitoring unit 2 is coupled to the electrocardio sensing unit 1 and is used for receiving the first digital electrocardiosignals and determining first voltage values corresponding to a first number of first monitoring points on the first digital electrocardiosignals.
And the processing unit 3 is coupled to the monitoring unit 2 and configured to compare each first voltage value corresponding to each first monitoring point with a corresponding preset reference value, determine a difference value, determine that the patient is arrhythmia if the absolute value of the difference value is not within the corresponding preset threshold range, and otherwise, determine that the patient is normal in rhythm.

In order to convert the digital cardiac electrical signal into a first number of voltage values corresponding to each monitoring point, in a preferred embodiment, the monitoring unit 2 may comprise a conversion unit 21 for converting the first digital cardiac electrical signal into a first number of voltage values corresponding to the first monitoring point, for converting the second digital cardiac electrical signal into a second number of voltage values corresponding to the first number of second monitoring point, and for converting the third digital cardiac electrical signal into a third number of voltage values corresponding to the first number of third monitoring point.
In a preferred embodiment, the electrocardiograph sensing unit 1 may include an electrocardiograph sensor 11, an electrocardiograph signal conditioning unit 12, and an analog-to-digital conversion unit 13, see fig. 2. The electrocardiograph sensor 1 is configured to acquire simulated electrocardiograph signals of a patient in a treatment state, a normal state, and a test state, and the simulated electrocardiograph signals of the patient in the treatment state, the normal state, and the test state acquired by the electrocardiograph sensor 1 may further include interference signals such as an electromyogram signal and a respiratory signal of a human body, so the electrocardiograph signal conditioning unit 12 is configured to perform denoising processing on the acquired simulated electrocardiograph signals, for example, filter the interference signals such as an electromyogram signal and a respiratory signal existing in the simulated electrocardiograph signals. Generally, the analog electrocardiographic signal acquired by the electrocardiograph sensor 11 is very weak, usually in the order of microvolts to millivolts, and in order to facilitate drawing of an electrocardiographic waveform, the analog electrocardiographic signal needs to be amplified, so that the electrocardiographic signal conditioning unit 12 is further configured to amplify the analog electrocardiographic signal after denoising the analog electrocardiographic signal, so as to obtain an amplified analog electrocardiographic signal; the analog-to-digital conversion unit 13 is configured to convert the amplified analog electrocardiographic signal into a digital electrocardiographic signal.
In particular implementations, the first number of first monitoring points may be determined based on the sampling locations. In an example, the first number of first monitoring points may respectively correspond to a specific sampling position of the electrocardiographic signal, for example, the first number of monitoring points may be set to 5 monitoring points based on a rule of the electrocardiographic waveform, and the 5 monitoring points may respectively correspond to one sampling point on the P wave of the electrocardiogram, three sampling points on the QRS complex, and one sampling point on the T wave. In one example, these 5 monitoring points may correspond to sample point 1 on the P-wave peak, sample point 2 on the Q-wave peak, sample point 3 on the R-wave peak, sample point 4 on the S-wave peak, and sample point 5 on the T-wave peak, respectively, see fig. 3. Of course, in specific implementation, other numbers of monitoring points may be set, and generally, the higher the number of monitoring points is, the higher the accuracy of determining whether the arrhythmia is occurring later, for example, 10 monitoring points may be set in one example, but it should be noted that even in the case of setting 5 monitoring points, the 5 monitoring points may be set as sampling points at other sampling positions on the electrocardiogram waveform. In another example, based on the rule of the electrocardiographic waveform, the monitoring points may be set by equally dividing the time period occupied by the heartbeat waveform of one cycle of the patient, for example, on the basis of setting the first number of monitoring points as 5 monitoring points, 5 monitoring points may be set by equally dividing the time period occupied by the heartbeat waveform of one cycle of the patient five times, that is, the first equal dividing time point of the time period occupied by the heartbeat waveform of one cycle of the patient is set as the 1 st monitoring point, the second equal dividing time point of the time period occupied by the heartbeat waveform of one cycle of the patient is set as the 2 nd monitoring point, the third equal dividing time point of the time period occupied by the heartbeat waveform of one cycle of the patient is set as the 3 rd monitoring point, the fourth equal dividing time point of the time period occupied by the heartbeat waveform of one cycle of the patient is set as the 4 th monitoring point, the fifth bisection point of the time period occupied by the heartbeat waveform of one cycle of the patient is set as the 5 th monitoring point.
In order to determine the preset reference value, the ecg sensing unit 1 is further configured to acquire a second number of digital ecg signals of the patient in a normal state, for example, before performing an operation on the patient, the ecg sensor 11 is used to acquire 5 minutes of ecg data of the patient, and if the heart rate of the patient in a quiet state before performing the operation is 75 times/minute, 375 analog ecg signals are generated in 5 minutes, so the second number may be set to 375 in an example. Then, the electrocardiographic signal conditioning unit 12 performs denoising and amplification processing on the 375 parts of analog electrocardiographic signals, and sends the processed signals to the analog-to-digital conversion unit 13, the analog-to-digital conversion unit 13 converts the 375 parts of analog electrocardiographic signals into 375 parts of digital electrocardiographic signals, and sends the 375 parts of digital electrocardiographic signals to the monitoring unit 2, after receiving the 375 parts of digital electrocardiographic signals, the monitoring unit 2 determines each digital electrocardiographic signal corresponding to the first number of second monitoring points for each part of digital electrocardiographic signals, and then determines each corresponding voltage value according to each digital electrocardiographic signal.
For example, in one example, for each of the 375 digital electrocardiographic signals, digital electrocardiographic signals corresponding to 5 monitoring points are determined, and then corresponding 5 voltage values are determined according to the digital electrocardiographic signals. Assume that the 5 monitoring points determined for the 1 st part of the 375 parts of the digital electrocardiosignals are respectively: a. the11、A12、A13、A14And A15And the 5 voltage values corresponding to the digital electrocardiosignals corresponding to the 5 monitoring points are assumed to be: v11、V12、V13、V14And V15(ii) a Further assume that the 5 monitoring points determined by the 2 nd digital electrocardiosignal in the 375 parts of digital electrocardiosignals are respectively: a. the21、A22、A23、A24And A25And the 5 voltage values corresponding to the digital electrocardiosignals corresponding to the 5 monitoring points are assumed to be: v21、V22、V23、V24And V25(ii) a Further assume that the 5 monitoring points determined by the 3 rd digital electrocardiosignal in the 375 th digital electrocardiosignals are respectively: a. the31、A32、A33、A34And A35And the 5 voltage values corresponding to the digital electrocardiosignals corresponding to the 5 monitoring points are assumed to be: v31、V32、V33、V34And V35(ii) a Further assume that the 5 monitoring points determined by the 4 th digital electrocardiosignal in the 375 parts of digital electrocardiosignals are respectively: a. the41、A42、A43、A44And A45And the 5 voltage values corresponding to the digital electrocardiosignals corresponding to the 5 monitoring points are assumed to be: v41、V42、V43、V44And V45(ii) a Further assume that the 5 monitoring points determined by the 5 th digital electrocardiosignal in the 375 th digital electrocardiosignals are respectively:A51、A52、A53、A54and A55And the 5 voltage values corresponding to the digital electrocardiosignals corresponding to the 5 monitoring points are assumed to be: v51、V52、V53、V54And V55(ii) a By analogy, further assume that the 375 th digital electrocardiosignal of the 375 parts of digital electrocardiosignals determines 5 monitoring points respectively as follows: a. the3751、A3752、A3753、A3754And A3755And the 5 voltage values corresponding to the digital electrocardiosignals corresponding to the 5 monitoring points are assumed to be: v3751、V3752、V3753、V3754And V3755
Then, for the ith monitoring point in each of the 375 digital electrocardiosignals, the average voltage value V corresponding to the monitoring point can be determined by the following formula (1)i Normal average
Figure BDA0003162037350000071
In the formula (1), the value range of i is a positive integer from 1 to 5, and the value range of j is a positive integer from 1 to 375.
For example, for the 1 st monitoring point in each 375 copies of digital electrocardiosignals, the average voltage value corresponding to the monitoring point can be determined to be
Figure BDA0003162037350000072
For the 2 nd monitoring point in each part of the 375 parts of the digital electrocardiosignals, the average voltage value corresponding to the monitoring point can be determined to be
Figure BDA0003162037350000073
For the 3 rd monitoring point in each part of the 375 parts of the digital electrocardiosignals, the average voltage value corresponding to the monitoring point can be determined to be
Figure BDA0003162037350000081
For the 4 th monitoring point in each part of the 375 parts of the digital electrocardiosignals, the average voltage value corresponding to the monitoring point can be determined to be
Figure BDA0003162037350000082
For the 5 th monitoring point in each part of the 375 parts of the digital electrocardiosignals, the average voltage value corresponding to the monitoring point can be determined to be
Figure BDA0003162037350000083
Thus, V can be set to 375 digital electrocardiosignals based on setting the first number of monitoring points to 5 monitoring points and the second number of second digital electrocardiosignals1 Normal averageAs a reference value corresponding to the 1 st monitor point, V is set2 Normal averageAs a reference value corresponding to the 2 nd monitor point, V is set3 Normal averageAs a reference value corresponding to the 3 rd monitoring point, V4 Normal averageAs a reference value corresponding to the 4 th monitor point, V is set5 Normal averageAs a reference value for the 5 th monitoring point.
After determining the reference value, the ecg sensing unit 1 is further configured to acquire a third number of digital ecg signals of the patient in a test state, for example, in one embodiment, the electrode needle releases the treatment pulse in the test state, in order to determine the preset threshold range. The electrocardiographic data of the patient is acquired by the electrocardiographic sensor 11 for a period of time (for example, 12.5 seconds), and in a general case, the period of time for acquiring the electrocardiographic data by the electrocardiographic sensor 11 needs to be considered in combination with the operation time length, and assuming that 10 analog electrocardiographic signals of the patient in the period of time are acquired, the third number may be set to 10. Then the electrocardiosignal conditioning unit 12 denoises and amplifies the 10 parts of analog electrocardiosignals, and sends the processed signals to the analog-to-digital conversion unit 13, then the analog-to-digital conversion unit 13 converts the 10 parts of analog electrocardiosignals into 10 parts of digital electrocardiosignals, and sends the 10 parts of digital electrocardiosignals to the monitoring unit 2, after receiving the 10 parts of digital electrocardiosignals, the monitoring unit 2 determines each digital electrocardiosignal corresponding to the first number of third monitoring points aiming at each part of digital electrocardiosignals, and then determines each corresponding voltage value according to each digital electrocardiosignal.

Now, continuing with the above-mentioned patient as an example, in the subsequent treatment, after obtaining the xth analog electrocardiographic signal of the patient in the treatment state through the electrocardiographic sensor, obtaining the yth analog electrocardiographic signal of the patient in the treatment state through the electrocardiographic sensor, after performing denoising, amplification and analog-to-digital conversion, obtaining the yth digital electrocardiographic signal, and further assuming that the 5 monitoring points determined for the yth digital electrocardiographic signal are respectively: d11、D12、D13、D14、D15Further, it is assumed that 5 voltage values corresponding to 5 digital electrocardiosignals corresponding to the 5 monitoring points are respectively: 1.1V, 0.95V, 2.1V, 0.65V, and 1.2V, that is, the voltage value corresponding to the digital electrocardiographic signal of the 1 st monitoring point in the 5 monitoring points is 1.1V, the voltage value corresponding to the digital electrocardiographic signal of the 2 nd monitoring point in the 5 monitoring points is 0.95V, the voltage value corresponding to the digital electrocardiographic signal of the 3 rd monitoring point in the 5 monitoring points is 2.2V, the voltage value corresponding to the digital electrocardiographic signal of the 4 th monitoring point in the 5 monitoring points is 0.65V, and the voltage value corresponding to the digital electrocardiographic signal of the 5 th monitoring point in the 5 monitoring points is 1.2V. Then, the voltage value corresponding to the digital electrocardiosignal of the 1 st monitoring point in the 5 monitoring points is 1.1V and the average voltage value V corresponding to the 1 st monitoring point calculated based on 375 parts of electrocardio data of the patient in the normal state1 Normal averageIf the comparison is made at 1.2V, the voltage value 1.1V corresponding to the digital electrocardiographic signal of the 1 st monitoring point of the 5 monitoring points can be determined to be the average voltage value V corresponding to the 1 st monitoring point calculated based on 375 electrocardiographic data of the patient in the normal state1 Normal averageThe absolute value of the difference between 1.2V and 0.1V is 0.1V, and 0.1V is within the above-mentioned preset threshold range of 0.08V to 0.12V determined for the 1 st monitoring point, so that the electrocardiographic data corresponding to the 1 st monitoring point of the 5 monitoring points can be judged to be normal.
Then, the voltage value corresponding to the digital electrocardiosignal of the 2 nd monitoring point in the 5 monitoring points is set to be 0.95V and the average voltage value V corresponding to the 2 nd monitoring point calculated based on 375 parts of electrocardio data of the patient in the normal state2 Normal averageIf the comparison is made at 0.8V, the voltage value 0.95V corresponding to the digital electrocardiographic signal at the 2 nd monitoring point of the 5 monitoring points can be determined to be the average voltage value V corresponding to the 2 nd monitoring point calculated based on 375 electrocardiographic data of the patient in the normal state2 Normal averageThe absolute value of the difference between 0.8V and 0.15V is 0.15V, and 0.15V is not within the above-mentioned preset threshold range of 0.08V to 0.12V determined for the 2 nd monitoring point, so that it can be determined that the electrocardiographic data corresponding to the 2 nd monitoring point of the 5 monitoring points is abnormal.

In the case that the first number of monitoring points is set to 5 monitoring points, although the electrocardiographic data corresponding to the 1 st monitoring point, the 3 rd monitoring point and the 5 th monitoring point in the Y-th digital electrocardiographic signal are normal, since the electrocardiographic data corresponding to the 2 nd monitoring point and the 4 th monitoring point in the Y-th digital electrocardiographic signal are abnormal, the Y-th digital electrocardiographic signal of the patient can be judged to be abnormal, so that the Y-th analog electrocardiographic signal of the patient can be judged to be abnormal, and further the arrhythmia of the patient at the moment can be judged.
In the specific implementation, for the sake of patient safety, it is possible to determine that the cardiac rhythm of the patient is abnormal as long as there are 1 monitoring point corresponding to the cardiac electric data of the patient.
In an optional embodiment, the electrocardiographic sensor is used to collect the 5-minute electrocardiographic data of the patient, and then 375 parts of simulated electrocardiographic signals can be obtained, and the simulated electrocardiographic data of the patient for 5 minutes is collected, and then the collected 5-minute simulated electrocardiographic data is segmented based on the rule of electrocardiographic waveforms to obtain the electrocardiographic signal. Similarly, the above-mentioned acquiring of the electrocardiographic data of the patient for a period of time (for example, 12.5 seconds) by the electrocardiograph sensor can then obtain 10 parts of electrocardiographic data, which is actually obtained by acquiring the simulated electrocardiographic data of the patient for a period of time by the electrocardiograph sensor and then segmenting the acquired simulated electrocardiographic data based on the rule of the electrocardiographic waveform.
Furthermore, in an alternative embodiment, the monitoring unit 2 is further configured to monitor a heart rate of the patient, and the processing unit 3 is configured to determine that the patient is arrhythmia when the heart rate of the patient is determined not to be within a normal range. For example, if a normal adult has a heart rate of 60-100 beats/minute in a resting state, and the monitoring unit 2 monitors that the heart rate of the patient exceeds 100 beats/minute, the processing unit 3 may determine that the patient is tachycardia, thereby determining that the patient has arrhythmia. If the monitoring unit monitors that the heart rate of the patient is lower than 60 times/min, the processing unit 3 can judge bradycardia, so as to judge that the patient has arrhythmia.
In an example, an error range may also be set, and if the heart rate monitored by the monitoring unit is within the error range compared with the normal heart rate of the patient, the processing unit determines that the rhythm of the heart of the patient is normal, otherwise, determines that the rhythm of the heart of the patient is abnormal. For example, when the error range is set to 5 times, if the monitoring unit monitors that the heart rate of a patient is 75 times/min in a quiet state before operation, and if the heart rate of the patient occurs less than 70 times/min or more than 80 times/min during operation, the processing unit may determine that the patient has arrhythmia.
After determining the patient's arrhythmia, the processing unit 3 may also be configured to send an instruction to the composite steep pulse therapy device to control the operation of the composite steep pulse therapy device to be stopped. For example, after the processing unit determines the arrhythmia of the patient, the processing unit may send an instruction to the composite steep pulse treatment device by outputting a logic high/low level to control to stop operating the composite steep pulse treatment device.
