Research Hotspot and Evolution Analysis of ECG from the Perspective of Knowledge Map

Abstract

In this paper, knowledge mapping technology is used to analyze the relevant literature of ECG research in China, and the research status, research hotspot and trend in this field are statistically analyzed. CiteSpace V is used to carry out data visualization analysis on the literature retrieved from CNKI database. Through the analysis, we can see that the research of ECG based disease diagnosis has achieved sustainable development in recent years, but the high influential authors pay less attention to the research in this field. The core of the research is mainly focused on wavelet transform, feature extraction, classification and recognition, and the research strength in this field still needs to be strengthened.
