Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0031] In this embodiment, the identification of the R-wave of the electrocardiographic signal is implemented through the following steps.

[0032] Step S100: Acquiring peaks in the ECG signal.

[0033] The electrocardiographic signal is sampled at a certain sampling frequency, and the collected sample points are arranged in time order to form the waveform of the electrocardiographic signal. The peak refers to the maximum point of the amplitude within a wavelength range, and the signal with the largest amplitude within a wavelength range of the acquired ECG signal wavefor...

Abstract

Disclosed is a recognition method of R waves of electrocardiosignals. By smoothing the electrocardiosignals, high-frequency noise burrs and baseline shift are removed, the wave crest is recognized based on the change of the slope of sampling points, the heights of a rising edge and a falling edge which correspond to the wave crest are calculated, and the R waves can be well recognized based on theaverage height accumulation amount of the wave crest within a first distance range and the magnitude of the first wave crest of intermediate waves within the first distance range; moreover, the electrocardiosignals can be utilized according to the features of the R waves, an algorithm is simple, the influence of baseline drift on the result cannot be caused, and thus the result is more accurate;meanwhile, there is no need to set a threshold value in advance according to personal conditions, and the universality is better.

Description

technical field [0001] The present application relates to the technical field of electrocardiographic signal detection, in particular to a method, device, and computer equipment for R-wave recognition of electrocardiographic signals. Background technique [0002] The ECG is made up of a series of wave groups, each wave group representing each cardiac cycle. A wave group includes P wave, QRS complex, T wave and U wave. (1) P wave: The excitation of the heart originates from the sinoatrial node, and then conducts to the atrium. The P wave is produced by atrial depolarization and is the first wave in each wave group, which reflects the depolarization process of the left and right atria. The first half represents the right atrium and the second half represents the left atrium. (2) QRS complex: A typical QRS complex consists of three closely connected waves. The first downward wave is called the Q wave, and a high-pointed upright wave following the Q wave is called the R wave....
