Technical Field
The invention relates to the technical field of signal processing, in particular to a method and a device for generating an interval of heart beat difference data sequence.
Background
An Electrocardiogram (ECG) signal, which is an electrical signal that reflects heart activity. There are 3 typical waveforms in an ECG signal: p-wave, QRS complex (consisting of Q-wave, R-wave, and S-wave), and T-wave. Among them, the QRS complex is the most characteristic waveform, and its higher amplitude (the maximum amplitude point is the peak point of R wave, called as R point) makes the QRS complex easier to identify compared with P wave and T wave. In an ECG signal, the time interval of adjacent R points is specifically considered as one cardiac cycle time, called heart beat interval. The inter-beat data is a necessary parameter for calculating the heart rate and heart rate derivative data, and corresponding inter-beat data sequences need to be extracted from the ECG signal when the ECG signal is subjected to data analysis.

The ECG signal is specifically an electrocardiogram signal acquired from an electrocardiogram device (such as an electrocardiogram machine, a bedside electrocardiograph monitor, a dynamic electrocardiograph recorder, etc.). The sequence of interval difference data is obtained by processing a sequence of interval data, which in turn is obtained by extracting the time intervals of adjacent R points from the ECG signal, so that the ECG signal needs to be obtained before multi-modal processing of the sequence of interval difference data from the sequence of interval data.
Step 2, carrying out QRS complex identification processing on the ECG signal to generate a QRS complex data sequence;
wherein the QRS complex data sequence comprises a plurality of QRS complex data; QRS complex data includes Q point data, R point data, and S point data.

the method specifically comprises the following steps: step 1061, extracting a specified number of interval difference data from the end of the interval difference data sequence to form a coefficient calculation factor data sequence;
wherein the sequence of coefficient calculation factor data comprises a plurality of inter-beat interval difference data;
for example, the interval difference data sequence is { Δ RR }1，ΔRR2…ΔRRj…ΔRR98Designating that 30 interval difference data are extracted from the end of the interval difference data sequence to constitute a coefficient calculation factor data sequence, the coefficient calculation factor data sequence should be { Δ RR }69…ΔRR98}；

specifically, the common accumulation calculation processing is to directly sum all the inter-beat interval difference data to obtain an inter-beat interval difference data sequence coefficient;
for example, the coefficient calculation factor data sequence is { Δ RR69…ΔRR98Directly after summing all the inter-beat interval difference data,wherein, the value range of x is from 1 to 30;
weighting accumulation calculation processing, namely weighting processing is carried out on each interval difference data to obtain weighted difference data, and then summing processing is carried out on all weighted difference data to obtain interval difference data sequence coefficients;

wherein the coefficient classification threshold range comprises a plurality of coefficient classification sub-ranges; the coefficient classification sub-range includes an upper threshold and a lower threshold.
Here, the correspondence relationship between the upper threshold and the lower threshold included in the coefficient classification sub-range and the differential sequence mode is: when the upper limit threshold and the lower limit threshold are specific time data, a difference sequence mode for generating the inter-beat interval difference data sequence is an adjacent difference sequence or a front-back difference sequence; when the upper and lower thresholds are percentage data, the differential sequence pattern generating the sequence of interval difference data should be adjacent differential normalized sequences or adjacent differential average normalized sequences.
For example, the coefficient classification threshold range includes 3 coefficient classification sub-ranges, which are a sinus rhythm coefficient classification sub-range, a bradycardia coefficient classification sub-range and a tachycardia coefficient classification sub-range, and each sub-range has a pair of upper and lower threshold values; when the heart beat interval difference data sequence coefficient is in the sinus rhythm coefficient classification sub-range, classifying the heart beat interval difference data sequence into sinus rhythm; when the heart beat interval difference data sequence coefficient is in the bradycardia coefficient classification sub-range, the heart beat interval difference data sequence classification is specifically bradycardia; the interval difference data series classification is in particular tachycardia, when the interval difference data series coefficients are within a tachycardia coefficient classification sub-range.
