本篇論文提出「有效偵測心電圖信號之Q點與S點位置的PTQS演算法」，它是以Pan與Tompkins兩位教授提出的PT演算法為理論基礎。PTQS演算法在本篇論文中，是由如下的三個演算法所組成，分別是：(a)PTRA演算法：主要功能是要獲得FRW信號；(b)FRWA演算法：主要功能是以獲得的FRW信號為參考指標，目的是要偵測心電圖信號之R點的位置；(c)FQSA演算法：主要功能是以R點的位置當基準，目的是要偵測心電圖信號之Q點與S點的位置。本篇論文最後是以MIT-BIH心律不整資料庫中的相關檔案來評估所提方法的效能。經多次的測試，尋找心電圖信號之Q點與S點位置的平均失敗率(failed detection rate)為0.5999%。依據實驗的結果，本篇論文所提出的PTQS演算法是一個方法簡單、偵測快速、及效率高的方法。

This study proposes an effective PTQS algorithm for detecting the Q and S points of ECG signals. The proposed algorithm is based on the PT algorithm proposed by Pan and Tompkins. The proposed PTQS algorithm is composed of the following three sub-algorithms: (a) PTRA algorithm for obtaining the FRW signal; (b) FRWA algorithm by using the FRW signal as a reference index to detect the position of the R point of the ECG signal; (c) FQSA algorithm by using the position of the R point as the reference to detect the Q and S points of the ECG signal. The proposed algorithm is evaluated by the relevant files in the MIT-BIH arrhythmia database. After experiments, the average failure rate of the Q and S points of the ECG signal was about 0.5999%. Experimental results show that the proposed PTQS algorithm has advantages of simple method, fast detection, and high performance.
