摘要
为客观评估国产和进口心电图机设备的水平和差异情况,该研究深入对比验评了 5 台国产心电图机和 1 台进口心电图机的性能指标及可靠性.结果表明,国产样机的低频特性、对心电图波形间期和时限的自动测量准确性次于进口样机,但高频响应、基线稳定性、抗噪声自动测量稳定性优于进口样机.其他项测试的性能指标在国产和进口心电图机样机间并无明显不同.通过分析国产样机和进口心电图机的对比结果,可在一定程度上反映出目前国产心电图机设备与进口设备间的差异,为国产心电图机设备的研发改进提供参考.
Abstract
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.
