Distinguishing device and equipment for malignant ventricular arrhythmia

Abstract

The invention discloses a device for discriminating malignant ventricular arrhythmia. After the sampling module discretely samples the continuous ECG signal; the amplitude-frequency characteristic extraction module extracts the amplitude-frequency characteristic of the signal and obtains a matrix; then the frequency band selection module Select the vector of the preset frequency band from the matrix to obtain a new matrix; then the feature extraction module will select the column vector of the preset number with the largest variance from the new matrix as the feature vector of the signal; the classification module will then The feature vector is input into a pre-trained classifier to obtain a classification result; finally, the discrimination module judges whether the electrocardiographic signal is a malignant ventricular rhythm according to the classification result. It can be seen that the device can select a preset number of vectors with the largest variance from the vectors of the preset frequency band as feature vectors, which effectively reduces the amount of calculation of the classifier and saves the time spent on discrimination. The present invention also provides a device for judging malignant ventricular rhythm, the function of which is corresponding to that of the above-mentioned device.

Description

technical field [0001] The invention relates to the field of medical signal processing, in particular to a device and equipment for distinguishing malignant ventricular rhythm. Background technique [0002] Malignant ventricular arrhythmias are a series of cardiac arrhythmias that potentially or explicitly affect the hemodynamic state, leading to hypotension, shock, acute left heart failure, and even syncope and sudden death. Typical heart rhythms in malignant ventricular rhythm include Ventricular Fibrillation (VF for short), Ventricular Tachycardia (VT for short), and Ventricular Flutter (VFL for short). Discrimination and timely treatment of patients may seriously endanger the lives of patients. [0003] Studies have shown that the best rescue time after the occurrence of malignant ventricular arrhythmia is the first 3 to 5 minutes. Early electrical defibrillation is the most effective treatment for malignant ventricular arrhythmias, and the premise of implementing elec...
