Problems solved by technology

[0003] However, there are still many challenges in the automatic analysis and detection of cardiac arrhythmia in ambulatory ECG
The Holter acquisition time is long, and the user can carry out daily activities. In this way, the signal is susceptible to noise such as motion artifacts, baseline drift, and power frequency interference. Especially motion artifacts can interfere with heartbeat detection and arrhythmia identification , and the amount of data is large, the analysis time is long
In addition, the waveform of ventricular arrhythmia is complex and changeable, and there are individual differences

Abstract

The invention provides a physiological parameter processing method which comprises the following steps: detecting preprocessed dynamic electrocardiogram data to obtain heart beat in the data; performing clustering analysis on all the heart beats by using template matching to obtain a clustering result; and performing artifact detection on the clustering result, determining to-be-classified heart beats, and classifying the to-be-classified heart beats by using a neural network. The invention further provides a corresponding device and a medical equipment. According to the invention, the accuracy of heart rhythm classification can be effectively improved.

Description

technical field [0001] The disclosed embodiments of the present application relate to the technical field of biomedical signal processing, and more specifically, relate to a physiological parameter processing method, device and medical equipment. Background technique [0002] The detection method of arrhythmia is usually an electrocardiogram, and then the situation of arrhythmia is artificially diagnosed according to the electrocardiogram. [0003] However, Holter still has many challenges in terms of automatic analysis and detection of arrhythmia. The Holter acquisition time is long, and the user can carry out daily activities. In this way, the signal is easily affected by noise such as motion artifacts, baseline drift, and power frequency interference. In particular, motion artifacts can interfere with heartbeat detection and arrhythmia identification , and the amount of data is large, and the analysis time is long. In addition, the waveform of ventricular arrhythmia is ...
