摘要:	根據台灣衛生署報告，心血管疾病始終占據國人十大死因的第二順位，而突發性心臟衰竭的不可預測性與不適當的第一時間救助（first aid），更經常導致院外病人的高死亡率（2% ~ 8%）。此外，臨床心臟衰竭急救經常使用手指測量頸動脈的血管脈動作為診斷依據，然而，此種不精確的第一救助量測診斷方式，經常造成誤診並導致不適當的救助行為。因此，一種可攜帶式心電圖監控系統的開發，將能夠有效提高病人的存活率。　　本研究目的在於建構一個可攜式即時監控心電訊號的系統，系統經由微處理機（Microprocessor）即時量測並判斷使用者的心電圖。當偵測到心電圖異常時，微處理器將接收全球定位系統（GPS）的位置，並將有問題的心電圖片段經過 FSK 數位調變系統，經由手機的語音通道傳到醫學中心。醫學中心經過解調，可以定位患者的位置並解調出心電圖波形，並通知最接近患者的醫療中心前往救援，爭取治療時間。　According to statistical report from Department of Health in Taiwan , heart disease has been ranked as the 2nd leading cause of death. Cardiac arrest in out-of-hospital patients usually causes a worse survival rate (2-8%) due to its unpredictability and inappropriate first aid. Furthermore, studies have shown that rescuers often make a mistake when checking the carotid pulse in an emergency, whether they are healthcare professionals or lay persons.Therefore, a personal-care system for real-time ECG monitoring and immediately communication with hospital in emergent situation is crucial. 　In this thesis, we have developed a mobile phone based ECG monitoring system. User’s ECG signals are analyzed by a microprocessor and abnormalities in ECG are detected. Once heart failure, including cardiac arrest and etc., has been detected, user’s position (localized by a global positioning system, GPS) as well as his/her abnormal ECG epoch will be modulated and transmitted by means of frequency shift keying (FSK) technique via voice channel to remote health care centers for assistances. Remote health care centers receive the distress call and demodulate the signal transmitted from the user, so that aid center closest to the user can be informed to help the patient in shortest time.
