Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The core of the embodiments of the present invention is to provide a method for judging the timing of electrical defibrillation to accurately determine the timing of electrical defibrillation; another core of the present invention is to provide a device, equipment and a computer-readable storage medium for judging the timing of electrical defibrillation , all have the above beneficial effects.

In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a flowchart of a method for determining an electrical defibrillation timing according to an embodiment of the present invention. As shown in Figure 1, the method for judging the timing of electrical defibrillation includes:

S10: Collect the ECG signal of the target object, and convert the ECG signal into an ECG signal sequence.

At present, an electrocardiograph is generally used to collect the electrocardiographic signal of the target object, and since the collected electrocardiographic signal is generally a time domain signal, in order to facilitate calculation, the electrocardiographic signal needs to be converted into an electrocardiographic signal sequence. Specifically, sampling and processing the collected ECG signals in the time domain according to a preset sampling rule, and then subjecting the sampled ECG signals to fast Fourier transform to obtain an ECG signal sequence in the frequency domain.

S20: Select signal elements to be processed from the ECG signal sequence according to a preset rule.

The signal elements to be processed refer to the signal elements in the ECG signal sequence to be used in the current calculation. Specifically, the signal elements to be processed are selected from the ECG signal sequence according to preset rules. Generally, the signal elements in the ECG signal sequence that are close to the current moment are selected as the signal elements to be processed, which can improve the calculation of the target object in the subsequent steps. The real-time nature of the defibrillation value, thereby improving the accuracy of the judgment of the timing of electrical defibrillation.

S30 : Amplitude sequence is composed of signal elements greater than the adaptive threshold among the signal elements to be processed, and a frequency sequence is composed of frequencies corresponding to the signal elements.

It should be noted that, due to the unavoidable interference of other noise signals in the collected ECG signals, in this embodiment, by setting an adaptive threshold, the selected signal elements to be processed are compared with the adaptive threshold The thresholds are compared to filter out signal elements greater than the adaptive threshold, and the filtered signal elements are formed into an amplitude sequence; then the frequencies corresponding to each signal element in the amplitude sequence are obtained, and the obtained frequencies are formed into a frequency sequence .

It should be noted that the adaptive threshold is generally set according to the value of the selected signal element to be processed. In this embodiment, the adaptive threshold T ₁ =(s _max -s _min )×k, where s _max represents the signal element with the largest value among the selected signal elements to be processed, and s _min represents the selected signal element to be processed. The signal element with the smallest value; k represents the scale factor, and the value of the scale factor k is usually set to 30%.

S40: Calculate the electrical defibrillation value of the target object by using the amplitude sequence and the frequency sequence.

Specifically, after the selected signal elements to be processed are used to filter out the amplitude sequence and the corresponding frequency sequence is obtained by using the amplitude sequence, the electrical defibrillation value of the target object is calculated by using the amplitude sequence and the frequency sequence. Specifically, the following formula is used to calculate the electrical defibrillation value of the target object:

Among them, A _i represents each element in the amplitude sequence; f _i represents each element in the frequency sequence; i represents the ith element in the amplitude sequence or frequency sequence, and the ith element in the amplitude sequence is related to the frequency The i-th element in the sequence corresponds to each other; n represents the number of elements in the amplitude sequence or frequency sequence, both of which are n.

S50: Use the electrical defibrillation value and the preset electrical defibrillation threshold to determine whether the target object is suitable for electrical defibrillation at the current moment.

After the electrical defibrillation value of the target object is calculated, the electrical defibrillation value of the target object is compared with a preset electrical defibrillation threshold, and whether the target object is currently suitable for electrical defibrillation is determined according to the comparison result. Specifically, the electrical defibrillation threshold is preset, and then the magnitude relationship between the electrical defibrillation value and the electrical defibrillation threshold is determined. If the electrical defibrillation value is greater than the electrical defibrillation threshold, the result of the determination is that the current moment is suitable for electrical defibrillation; The defibrillation value is less than the electrical defibrillation threshold, and the result of the determination is that the current moment is not suitable for electrical defibrillation.

It should be noted that, due to the operation of screening the amplitude values in the ECG signal sequence in this embodiment, the acquired features representing the amplitude value sequence and the frequency sequence of the ECG signal are more obvious, so the collection target objects can be reduced. time of the ECG signal. Specifically, in the prior art, the ECG signal is generally collected for about 5 seconds, but this embodiment only needs to collect the ECG signal for about 1 second. By reducing the time for collecting the ECG signal, the delay of judgment is reduced, and the judgment is made. The results are more accurate.

A method for judging the timing of electrical defibrillation provided by an embodiment of the present invention collects the electrocardiographic signal of a target object and converts the electrocardiographic signal into an electrocardiographic signal sequence; Process the signal elements; and compose the signal elements larger than the adaptive threshold in the signal elements to be processed into an amplitude sequence, and compose the frequency sequence with the frequencies corresponding to the signal elements; by filtering out the signal elements larger than the amplitude threshold, it is possible to eliminate the The interference of the signal elements of the ECG signal makes it more accurate to use the amplitude sequence and frequency sequence to calculate the electrical defibrillation value of the target object, so that the electrical defibrillation value and the preset electrical defibrillation threshold can be used to judge whether the target object is suitable for the current moment. The judgment result of defibrillation is more accurate.

On the basis of the above embodiment, the present embodiment further illustrates and optimizes the technical solution. Specifically, the steps of collecting the ECG signal of the target object and converting the ECG signal into an ECG signal sequence specifically include:

Collect the ECG signal of the target object;

Determine whether the rhythm type of the ECG signal is a defibrillable rhythm type;

If so, convert the ECG signal into an ECG signal sequence.

It should be noted that, as a preferred implementation manner, in this embodiment, the ECG signal of the target object is collected in a preset period, and the ECG signal is converted into an ECG signal sequence.

It can be understood that the ECG signal of the target object is collected at a preset cycle, that is, the ECG signal is continuously updated, and the updated ECG signal is converted into an ECG signal sequence, so that the update is performed according to the preset rules. When the signal element to be processed is selected in the post-ECG signal sequence, the updated signal element to be processed can be obtained, so that the subsequent calculation of the electrical defibrillation value is more real-time, and the judgment result is more accurate.
