摘要: 
在台灣,心臟疾病長期以來都位於十大死因排行中,近幾年更高居第二,因此診斷心臟疾病及如何預防就顯得格外重要。心電圖(ECG)是目前判斷心臟活動最可靠的方法,藉由紀錄心臟活動的相關電氣訊號,可在心電圖紙上畫出心電圖,再由醫師判斷心臟是否有異常,進而評估並加以治療。心臟疾病很多是瞬間的或發生時間極短的,這會造成當感到心臟不舒服時,馬上趕到醫院就醫,做了心電圖檢查,卻檢查不出是什麼原因,而讓醫生無法評估與治療,所以一種高精確度即時偵測系統是迫切需要的,以避免上述情形。本論文的重點是提出一個高精確度即時心室早期收縮(Premature Ventricular Contraction ,PVC)偵測系統。採用小波轉換偵測R波波峰,並提出一個全新的結合了兩種方法之PVC偵測演算法來加以偵測、判斷有無PVC的發生,第一種為波谷之和法,第二種為R_peak與最小值之和法,若發生病態則發出警告訊息給使用者。模擬與驗證採用MIT-BIH Arrhythmia Database (mitdb),最後使用FPGA實現我們的系統。

In Taiwan, heart disease has been in the top ten causes of death for a long time, and even at the second place in recent years, Thus the diagnosis of heart disease and how to prevent it is particularly important.Currently, Electrocardiogram (ECG) is the most reliable way to determine heart activity by record relevant electrical signal, which can be drawn on electrocardiogram paper to produce ECG. Doctor can diagnose whether there is abnormal, and further assess or treat.A lot of heart diseases occur in a moment or a very short time, and it will cause the patients to feel uncomfortable and then to go to the hospital to do ECG examination, but can not check out the reason so that the doctors can not assess and treat. Therefore, a high-precision real-time detection system is urgently needed to prevent the above situation.The focus of this thesis is to propose a high-precision real-time Premature Ventricular Contraction (PVC) detection system. We will use wavelet transform to detect R wave peaks and propose a new PVC detection algorithms that combines two methods to detect and determine whether the occurrence of PVC. The first method is the sum of trough and the second one is the sum of R_peak and minimum. If the morbid state happens, a warning message will be sent to the user.We simulate and verify the proposed system by using MIT-BIH Arrhythmia Database (mitdb). Finally, our system is implemented by FPGA.
