The Research on Electromagnetic Compatibility Testing and Rectification Technology of Electrocardiograph
In this study,with the combination of the structure and working principle of electrocardiographs,according to national standards,electrocardiographs used during registration and clinical use were subjected to electromagnetic compatibility testing,and the problems that arise were analyzed.The results showed that the electrocardiograph may exceed the standard limit when it is used for radiation emission,and it is vulnerable to electromagnetic interference when it is used for immunity tests such as electric rapid pulse group test.The collected images may affect normal clinical diagnosis,so it needs to be corrected.Therefore,during the operation of the electrocardiogram machine,it is necessary to collect and process digital signals,and pay attention to electromagnetic compatibility.
