Comparison and Evaluation on Performance of Electrocardiographs
To objectively evaluate the level and differences of domestic and imported electrocardiograph equipment,the performance indicators and reliability of 5 domestic electrocardiogram machines and 1 imported electrocardiogram machine were thoroughly compared and evaluated in this study.The results showed that the low frequency characteristics,automatic measurement accuracy of ECG waveform interval and time of the domestic prototype were inferior to those of the imported prototype,but the high frequency response,baseline stability and anti-noise automatic measurement stability were superior to those of the imported prototype.There was no significant difference in performance indicators between domestic and imported electrocardiogram machine prototypes for other tests.By analyzing the comparison results between domestic prototypes and imported electrocardiographs,it can to some extent reflect the differences between domestic and imported electrocardiograph equipment,providing reference for the research and development improvement of domestic electrocardiograph equipment.
