本研究以醫療照護為主軸,將醫療與電子、資訊科技相結合,發展出一套方便且能快速量測的手握式心電訊號與健康照護管理系統,以達到心血管疾病診斷與量得心電訊號之目的,屬於非侵入式生理訊號量測系統,因此能廣泛使用。依據心跳頻率、心跳速率、心電圖、心臟的電氣生理變化等幾項生理訊號特性,來對心臟病患者的病症做訊號上的量化診斷分析。對於訊號處理方面,本研究採用資料擷取卡,主要功能是將輸入的類比訊號數位化,融合電腦介面解讀人體心電訊號。將所得心電圖訊號,經由快速傅利葉轉換,於頻域上進行主要的分析工作,藉由大量取樣與比較分析,探索出人體生理病變的判別法則。
This research combines medical, electronic and information technology to develop a convenient and fast hand-held ECG (electrocardiogram) measurement system and medical care management system as a medical care in order to achieve measurement of ECG (electrocardiogram) signals with the purposes of cardiovascular disease diagnosis . This is a non-invasive physiological signal measuring system, therefore it can be widely to use. Based on the frequency of heart rate, heart rate, electrocardiogram, electric physiological changes of heart to quantify a cardiac’s physiology signal. For signal processing, this research uses DAQ card (Data Acquisition card) to process analog input signals. The ECG (electrocardiogram) signal will be obtained by using FFT (Fast Fourier Transform) in the frequency domain analysis of a major work by a lot of sampling and compared to find out some simple disease.
