BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Figure 1 The flowchart of the high-precision electrocardiographic physiological signal analysis method of the present invention. DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] In order to solve the problem that the existing technology cannot effectively analyze the electrophysiological signals, resulting in low accuracy and reliability of electrophysiological signal analysis and recognition, and cannot accurately identify cardiac abnormalities, resulting in low accuracy of diagnosis and prognosis, please refer to Figure 1 , this embodiment provides the following technical solutions:

[0062] A high-precision electrocardiographic signal analysis method comprises the following steps:

[0063] S1. Signal acquisition and processing: Collect the patient's real-time electrophysiological signals based on the smart sensor integrated on the smart wearable device, and process the patient's real-time electrophysiological signals based on the smart sensor to generate the patient's electrophysiological characteristic signals based on the smart sensor;

[0064] In this embodiment, collecting the patient's real-time electrophysiological signals includes:

[0065] Based on the smart sensors integrated on the smart wearable device, the patient's ECG signal, intracardiac electrogram, heart sound signal and myoelectric signal are monitored and continuously collected in real time in a quiet state to obtain the patient's real-time ECG signal based on the smart sensor;

[0066] Based on the smart sensors integrated on the smart wearable devices, the patient's blood pressure signal, respiratory signal, temperature signal and blood oxygen saturation signal are monitored and collected continuously in real time in a quiet state to obtain the patient's real-time physiological signals based on the smart sensors;

[0067] Wherein, the patient's real-time electrocardiographic and physiological signals based on the smart sensor are determined according to the patient's real-time electrocardiographic signals based on the smart sensor and the patient's real-time physiological signals based on the smart sensor.

[0068] It should be noted that the ECG signal is a signal that records the electrical activity of the heart through electrodes placed on the body surface. The ECG signal includes P wave, QRS complex and T wave, which represent the processes of atrial depolarization, ventricular depolarization and ventricular repolarization respectively.

[0069] Intracardiac electrograms are electrocardiograms recorded through intracardiac electrodes, providing more detailed information about the electrical activity of the heart, including the electrical activity of the atria, ventricles, and His bundle.

[0070] The heart sound signal is a heart sound signal recorded by a microphone or sensor placed on the body surface. The heart sound signal includes the first heart sound and the second heart sound, which represent the beginning of ventricular contraction and relaxation respectively.

[0071] EMG signals are muscle electrical activity signals recorded by electrodes placed on the body surface. In electrophysiology, EMG signals are mainly used to detect muscle activity around the heart.

[0072] The blood pressure signal is a blood pressure change signal recorded by a blood pressure sensor. The blood pressure signal includes systolic pressure and diastolic pressure, which represent the blood pressure levels during heart contraction and relaxation, respectively.

[0073] The respiratory signal is a respiratory movement signal recorded by a respiratory sensor. The respiratory signal includes respiratory frequency and respiratory depth, which reflects the functional state of the respiratory system.

[0074] The temperature signal is a body temperature change signal recorded by a temperature sensor. The body temperature change can reflect the metabolic state of the heart and body.

[0075] The blood oxygen saturation signal is a blood oxygen saturation change signal recorded by a blood oxygen saturation meter. The blood oxygen saturation reflects the oxygen content in the blood, which can reflect the functional status of the heart and respiratory system.

[0076] In this embodiment, the real-time electrophysiological signals of the patient based on the intelligent sensor are processed, including:

[0077] Acquire the patient's real-time electrophysiological signal based on the intelligent sensor, and perform filtering processing on the patient's real-time electrophysiological signal based on the intelligent sensor based on a median filter;

[0078] Wherein, according to the characteristics of the patient's real-time electrophysiological signal based on the intelligent sensor, the median filter window is determined, and when the size of the median filter window is determined, the size of the median filter window is smaller than the width of the P wave, the QRS complex wave and the T wave in the patient's real-time electrophysiological signal;

[0079] Based on the median filtering algorithm, the median of all data points in the median filter window is calculated to replace the data point in the center of the window, thereby eliminating isolated noise points and removing noise from the real-time electrophysiological signal of the patient based on the smart sensor, while retaining the edges and details of the real-time electrophysiological signal of the patient based on the smart sensor.

[0080] Specifically, determining the median filter window size includes:

[0081] Retrieve the width of P wave, QRS complex wave and T wave in the patient's real-time electrophysiological signal;

[0082] Retrieving the maximum width from the widths of the P wave, QRS complex wave and T wave in the real-time electrophysiological signal of the patient, and using the time length corresponding to the maximum width as the initial window;

[0083] Extracting the waveform widths of the P wave, QRS complex wave and T wave;

[0084] Obtaining a first window setting coefficient using the waveform widths of the P wave, QRS complex wave, and T wave;

[0085] The first window setting coefficient is obtained by the following formula:

[0086]

[0087] Among them, S 01 Indicates the first window setting coefficient; K p , K q and K t Respectively represent the time length corresponding to the waveform width of P wave, QRS complex wave and T wave; K c Indicates the preset time length reference value;

[0088] comparing the first window setting coefficient with a preset window setting coefficient threshold;

[0089] When the first window setting coefficient is lower than a preset window setting coefficient threshold, the median filter window is set according to a preset initial window size;

[0090] When the first window setting coefficient exceeds a preset window setting coefficient threshold, the median filter window is set using the signal dynamic range of the P wave, QRS complex wave and T wave in combination with the first window setting coefficient.

[0091] The technical effect of the above technical scheme is: the scheme retrieves the width of the P wave, QRS complex wave and T wave in the patient's real-time electrophysiological signal, and determines the size of the median filter window according to the characteristics of these waveforms. This method enables the filter window size to adapt to the patient's electrocardiographic signal characteristics, thereby improving the pertinence and effectiveness of the filtering. The scheme mentions that the maximum width is first determined as the initial window, and then the window size is further adjusted by calculating the first window setting coefficient. This method combines the main waveform characteristics of the electrocardiographic signal, so that the window size is more in line with the actual situation of the electrocardiographic signal, thereby improving the accuracy of the filtering. The scheme introduces a comparison mechanism between the first window setting coefficient and the preset window setting coefficient threshold. When the first window setting coefficient is lower than the threshold, the preset initial window size is adopted; when it exceeds the threshold, it is adjusted in combination with the signal dynamic range. This dynamic adjustment capability enables the filter to better adapt to the changes of different electrocardiographic signals and improves the stability and reliability of the filtering. By comprehensively considering the waveform width of the P wave, QRS complex wave and T wave and the signal dynamic range, the scheme can more accurately set the median filter window size, thereby optimizing the filtering effect. This helps reduce noise interference, improves the clarity and readability of ECG signals, and provides doctors with more accurate diagnostic evidence. Since the scheme can adaptively adjust the filter window size and optimize the filtering effect, it can more effectively extract and analyze ECG signal features. This helps doctors make diagnoses faster and improves diagnostic efficiency.

[0092] In summary, this technical solution improves the accuracy and stability of ECG signal processing by adaptively determining the median filter window size, optimizes the filtering effect, provides doctors with more accurate diagnostic basis, and also improves diagnostic efficiency.

[0093] Specifically, when the first window setting coefficient exceeds a preset window setting coefficient threshold, the median filter window is set by using the signal dynamic range of the P wave, QRS complex wave and T wave in combination with the first window setting coefficient, including:

[0094] When the first window setting coefficient exceeds a preset window setting coefficient threshold, retrieving the signal dynamic range of the P wave, QRS complex wave and T wave;

[0095] Obtaining a second window setting coefficient using the signal dynamic range of the P wave, QRS complex wave and T wave;

[0096] The second window setting coefficient is obtained by the following formula:

[0097]

[0098] Among them, S 02 Indicates the second window setting coefficient; D p , D q and D t Represents the signal dynamic range of P wave, QRS complex wave and T wave respectively; D c Indicates a preset signal dynamic range reference value;

[0099] The median filter window is set using the first window setting coefficient and the second window setting coefficient, wherein the size of the median filter window after the setting is obtained by the following formula:

[0100]

[0101] Among them, K h Indicates the size of the median filter window after setting; K s Indicates the initial window size; S 01 Indicates the first window setting coefficient; S 02 Indicates the second window setting coefficient; S y Indicates the preset window setting coefficient threshold.

[0102] The technical effect of the above technical solution is: when the first window setting coefficient exceeds the preset window setting coefficient threshold, the solution no longer relies solely on the initial window size or a single waveform width feature, but further considers the signal dynamic range of the P wave, QRS complex wave and T wave. This method of comprehensively considering multiple ECG signal characteristics makes the setting of the median filter window size more flexible and adaptable. By introducing the second window setting coefficient, the solution can more accurately reflect the changing characteristics of the ECG signal. By setting the median filter window in combination with the first window setting coefficient and the second window setting coefficient, the noise in the ECG signal can be more effectively removed while retaining the important features of the signal, thereby improving the accuracy of filtering. The solution uses two window setting coefficients to jointly determine the size of the median filter window, so that the performance of the filter is optimized. Through the set median filter window size formula, it can be ensured that the filter can achieve a good filtering effect under different signal characteristics, which can remove noise and retain the detailed information of the signal. Since the solution can adaptively adjust the median filter window size and optimize the filtering effect, the ECG signal features can be more effectively extracted and analyzed. This helps doctors to more accurately judge the patient's heart condition and improve the accuracy of diagnosis. This solution comprehensively considers multiple characteristics of ECG signals, including waveform width and signal dynamic range, so that the system can have better adaptability to different types of ECG signals. This design enhances the robustness of the system, allowing the system to maintain stable performance when facing different patients or different ECG signals.

[0103] In summary, this technical solution adaptively adjusts the median filter window size by comprehensively considering multiple characteristics of the ECG signal, thereby improving the adaptability and filtering accuracy of the filter, optimizing the filtering effect, improving the diagnostic accuracy, and enhancing the robustness of the system.
