Method and device for detecting the quality of ECG signal

Abstract

The invention provides a method and device for detecting the quality of an ECG signal. The method includes: performing energy envelope extraction on an ECG signal; performing a differential operationon the energy envelope; counting the number of zero-crossing points within a window by in a segmenting mode; and determining the quality of the signal according to a threshold. By using the energy envelope difference method, the method correlates the number of zero-crossing points with the quality of the ECG signal, that is, the quality of the ECG signal can be determined only by counting the number of zero-crossing points of the differential data, thereby achieving accurate determination of the quality of the ECG signal; compared with the traditional ECG quality analysis algorithm which has high complexity and must rely on strong hardware resources to achieve accurate determination of the quality of the ECG signal, this algorithm is simple and easy to implement and has low computational complexity.

Description

technical field [0001] The invention relates to the technical field of medical signal processing, in particular to a method and device for detecting the quality of electrocardiographic signals. Background technique [0002] In today's medicine, cardiovascular disease is one of the diseases with the highest morbidity and mortality, and effective prevention and diagnosis of heart disease has become one of the important problems that need to be solved urgently. ECG signals are the main basis for diagnosing cardiovascular diseases and evaluating heart function. Therefore, research on ECG signal detection and processing has been receiving much attention. As a non-invasive detection technology, ECG is simple, painless and harmless, etc. It has always been one of the main techniques for diagnosing heart disease and has played an extremely important role in the diagnosis of cardiovascular diseases. [0003] However, the collection of ECG signals is very easily affected by various f...
