Abstract: The research on the relationship between ECG sequence and angiocardiopathy is a classical topic in the study of the clinical diagnosis of heart disease.ECG is an important tool for the detection of heart disease,and long-term volu-me datas have been collected,so it has practical significance to deal with it.In this paper,we used the variable value ECG measurement system to dispose two types of ECG data,T wave change in sinus rhythm and normal ECG sequence to form 2D scatter map.The distribution characteristics and similarities and differences of the two types of ECG signals are displayed in a visual form.Compared with the traditional ECG,it has the characteristics of being intuitive and easy to understand,and the visualization results of the ECG sequences with different measurement variables are also listed in this paper.

Key words: Variable value ECG measurement,Visualization method,2D map
