摘　　要：目的:通过分析EGC-1C型心脑电图机检定仪在检测中的不确定度来源,评定心脑电图机检定仪的示值测量结果的不确定度。方法:着重对电压幅度、频率测量和走纸速度3个方面的不确定度来源进行了分析和评定。结果:依据JJ543-2008《心脑电图机检定规程》、JJG1041—2008《数字心电图机检定规程》、JJG1043—2008《脑电图机检定规程》的各项要求得出了相应的相对扩展不确定度。结论:经过计算和评定,心脑电图机检定仪的各项不确定来源的结果符合规程要求,可以检测临床上使用的心脑电图机,确保仪器的量值准确可靠。Objectiv Using the analysis on the source of uncertainty about EGC-1C to evaluate the measurement uncertainty of ECG machine. Methods： We focus on three aspects of the source of uncertainty, they are voltage amplitude, frequency measurement and paper speed. Results： According to JJ543-2008 ＂Verification Regulation for Electrocardiographs and Electroencephalographs,JJG1041-2008 ＇Verification Regulation for digital ECG＂, JJG1043-2008＂ Verification Regulation for Electroencephalographs＂, the relative expanded uncertainty can be corresponded. Conclusion： After the calculation and evaluation on the sources of uncertainty of heart electroencephalogram test instrument, the results meet the standard requirement, it also can be used to detect ECG on clinical operation and ensure accurate and reliable value of quantity.
