Embodiment Construction

[0048] The 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 used to explain the present application rather than limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation or object from another entity or operation or object, and do not necessarily require or imply that these entities or any such actual relationship or order between operations or objects. For example, "first" and "second" of the first semantic feature vector and the second semantic feature vector are used to distinguish two different semantic feature vectors.

Abstract

The embodiment of the invention discloses a method, device, equipment for determining the position of a QRS wave group, and a storage medium, and relates to the technical fields of ECG testing. The method comprises the following steps: acquiring a lead electrocardiosignal sequence, wherein the lead electrocardiosignal sequence comprises at least one QRS wave group; coding the lead electrocardiosignal sequence by using a coding neural network model to obtain a first semantic characteristic vector of the lead electrocardiosignal sequence; and decoding the first semantic characteristic vector byusing a decoding neural network model to obtain the position information of the QRS wave group in the lead electrocardiosignal sequence. Through adoption of the method, the technical problem that theanti-noise capability of detection of the QRS wave group is weak due to manual design characteristics in the prior art can be solved. A coding neural network model and a decoding neural network modelare constructed by using a machine learning mode, so that automatic detection of the QRS wave group can be realized, and the model obtained by training does not need manual design characteristics, andhas better performance, better generalization capability and stronger anti-noise capability.

Description

technical field [0001] The embodiments of the present application relate to the technical field of electrocardiogram detection, and in particular to a method, device, equipment and storage medium for determining the position of a QRS complex. Background technique [0002] The electrocardiographic signal is a signal that records the electrophysiological activity of the heart over a period of time, which can reflect the physiological information of the heart. ECG signals are usually represented in the form of waveform diagrams. Among ECG signals, P wave, T wave and QRS wave group are more important data for detecting the state of the heart. Among them, the P wave is an atrial depolarization wave, representing the excitation of the left and right atria. The T wave is the repolarization wave of the ventricles. The QRS complex reflects the changes in the depolarization potential and time of the left and right ventricles. The first downward wave in the QRS complex is the Q wav...
