摘　　要：自动心电诊断技术在近年来发展迅猛,相关的技术也涌现出不少。其中关于QRS波中R波检出的方法有很多,地位同等重要的P波检出的方法却相对较少。我们提出了一种针对P波检测的方法。通过使用Prony方法,将ECG(Electrocardiograph)波形先分离再检测,取得了不错的效果。本文试验数据均来自MIT ArrhythmiaDatabase,检出率达到97.8%。The technology of ECG （Electrocardiograph） auto-analysis has developed rapidly in recent years. There are lots of related techniques appearing. The majority is about R-peak detection. Although P-peak is important too, there are a few kinds of method about P-peak detection. In this paper is presented a new method for P-peak detection. Accord- ing to Prony analysis, ECG is separated first, and then detected. The method gets good result. Data in experiment are from MIT Arrhythmia Database. The reliability of this algorithm in accurately detecting the P location is 97.8 %.
