摘要：
A measuring system comprises a plurality of electrodes, an ECG processing device and an analysis device.The ECG processing device obtains a first analog differential signal and a second analog differential signal through the electrodes and generates a Lead-I ECG signal and a Lead-II ECG signal after processing the two analog differential signals, wherein the Lead-I ECG signal is vertical to the Lead-II ECG signal.The analysis device executes a trigonometric function based on the Lead-I ECG signal and the Lead-II ECG signal to calculate a degree variation of a cardiac axis, and the analysis device generates a cardiac axis degree variation waveform to as respiration related signal according to continuous degree variations.一種呼吸相關訊號量測系統,包括複數電極、心電訊號處理裝置及分析裝置。心電訊號處理裝置通過複數電極取得第一類比差動訊號與第二類比差動訊號,並經處理後產生兩導程方向互相垂直的第一導程心電圖訊號與第二導程心電圖訊號。分析裝置取得第一導程心電圖訊號與第二導程心電圖訊號並進行函數轉換,以得到心臟主軸的角度變化值。並且分析裝置依據連續的角度變化值產生心臟主軸角度變化波形。本發明的心臟主軸角度變化波形的主要頻率與人體的呼吸頻率高度正相關,因此可做為呼吸相關訊號來描述受測者的呼吸情形。1‧‧‧量測系統11‧‧‧第一電極12‧‧‧第二電極13‧‧‧第三電極14‧‧‧心電訊號處理裝置15‧‧‧分析裝置2‧‧‧使用者終端
