Analysis of Electromagnetic Compatibility Testing Methods for Electrocardiogram Machines
Electrocardiograph records the bioelectrical signal generated by the heart activity,so as to reflect the running state of the heart,to help diagnose heart-related diseases,has been widely used in clinical diagnosis.Due to the complexity of electrocardiosignal and its susceptibility to electromagnetic interference,it is different from common medical devices in electromagnetic compatibility testing.According to the relevant standards,this paper analyzes the electrocardiograph magnetic compatibility testing methods from the aspects of basic performance,compliance criteria,test layout and test requirements.
