Embodiment Construction

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0039] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0040] Prior to this application, the traditional ECG feature extraction method has the problems of excessive calculation and high calculation cost. Moreover, because the dimension of the feature vector is too high, the computational load of the classifier increases. Therefore, the present application preprocesses the electrocardiographic signal to obtain the...

Abstract

Embodiments of the present application provide a method for extracting electrocardiographic features, a method and a device for recognizing heart beats. The method includes: acquiring an electrocardiogram signal to be processed, and performing preprocessing on the electrocardiogram signal to be processed, and obtaining at least one first heart beat information corresponding to the electrocardiogram signal to be processed; performing adaptive Fourier transformation on each first heart beat information respectively Decomposing to obtain a first time-frequency representation corresponding to each first heartbeat information; extracting a corresponding first instantaneous frequency feature according to the first time-frequency representation corresponding to each first heartbeat information. The device is used to perform the above method. The features that can be extracted through the method of adaptive Fourier decomposition in the embodiment of the present application are all representative, can better reflect the type of the first heart beat information, and have no redundant useless features, so the calculation workload smaller.

Description

technical field [0001] The present application relates to the technical field of electrocardiographic signal processing, and in particular, to a method for extracting electrocardiographic features, a method and a device for identifying heart beats. Background technique [0002] Electrocardiography (ECG) is a signal that reflects potential changes from the body surface through an electrocardiographic sensor, and is a manifestation of the electrical activity process of the heart. The ECG signal has important reference value for the basic function and pathological research of the heart. The use of automatic diagnosis technology to identify and classify ECG signals can relieve doctors from the tedious work of monitoring patients' ECG signals for a long time, and also provides an important foundation for the currently developing family-use portable ECG monitoring equipment, so that users can Monitor and detect abnormal heart beats in time, so that you can seek medical treatment ...
