Method and device for identifying atrial fibrillation with ventricular premature contraction and atrial fibrillation with aberrant ventricular conduction

Abstract

The present invention is applicable to the field of medical technology and provides a method and a device for identifying atrial fibrillation with ventricular premature contraction and atrial fibrillation with aberrant ventricular conduction. The method comprises the following steps: acquiring electrocardiosignals; determining atrial fibrillation with wide QRS waves in the electrocardiosignals; extracting feature values of the atrial fibrillation with the wide QRS in the electrocardiosignals; obtaining a recognition result by an identification algorithm model based on the feature values; identifying the atrial fibrillation with the ventricular premature contraction and the atrial fibrillation with the aberrant ventricular conduction by using the identification algorithm model; and improving recognition accuracy and recognition efficiency of the atrial fibrillation with the ventricular premature contraction and the atrial fibrillation with the aberrant ventricular conduction. The methodsolves a problem that the electrocardiosignals of the atrial fibrillation with the ventricular premature contraction and the electrocardiosignals of the atrial fibrillation with the aberrant ventricular conduction cannot be accurately identified and distinguished in the prior art.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a method and device for identifying atrial fibrillation with premature ventricular and atrial fibrillation with arrhythmia. Background technique [0002] Before the heart contracts, there may be pre-excitement, which spreads to the whole body, causing potential differences on the body surface. These potential differences are recorded with an electrocardiograph, and the pattern is called an electrocardiogram. At present, through the comprehensive analysis of the ECG, it can be identified whether the ECG signal reflected by the ECG is the ECG signal combined with ventricular premature contraction (abbreviated as atrial fibrillation with premature ventricular contraction) or combined with indoor differential conduction (referred to as Atrial fibrillation with poor transmission) ECG signal. [0003] However, since the QRS wave of the atrial fibrillation accompanied by ventricular p...
