膈神经放电信号的一种计算机分析方法

A Computerized Analysis of Phrenic Nerve Discharge Signal

作者提出了一种膈神经放电信号的计算机分析方法,用以克服该信号手工分析时存在的问题。计算机通过对膈神经放电信号的采集、数字整流与滤波等处理后,可得到放电的包络图,从中能自动测量一些重要参数。动物实验证实程序能较好地执行这些功能。统计学分析表明,人工测量结果与计算机测量结果之间无显著性差异。

The authors offered a methodof computerized analysis to solve the pro-blems met in the manual measurement of thesignal of phrenic nerve discharge (PND).An envelope was gained via digital full-wave rectification and filter from the acqu-ired PND aignal. From it, some importantparameters were measured automatically.The program ran well in animal experi-ments. The values of the PND parameters.obtained by computer showed no significantdifference as compared with the averagedvalues measured manually by researchers.
