摘要

本論文發展一套架構於個人電腦(Personal Computer, PC)上之心電訊號監測系統，讓上班族能隨時透過PC掌握自己的生理狀況，預防過勞死悲劇之發生。此系統包含訊號處理端及健康評估端兩大單元，訊號處理單元涵蓋前端心電訊號放大電路、心電訊號擷取電路、USB電壓供給電路及控制電路，其特色為成本低於市售之同級產品。健康評估單元則架構在PC上，其可計算心率變異度並據以評估使用者目前的生理狀況，提供參考之用。我們設計了一套擷取心電訊號特徵值的軟體，並使用VB 6.0來完成人機溝通介面，系統之功能涵蓋輸入資料之分析、即時心跳之顯示、時域及頻域心電圖之顯示、時域心率變異度之計算以及健康評估之顯示。實驗結果顯示本系統具備應用於PC族健康監測之潛力。

This research develops a computer-based (PC-based) ECG signal measurement and monitoring system to allow PC user checking her/his health anytime to prevent death from overwork. This system is built with two main units: the signal processing unit and health evaluation unit. The former one, which consists of front-end ECG signal amplification circuit, electrocardiogram (ECG) signal acquisition circuit, USB power supply circuit, and control circuit, is featured a lower cost compared to the similar commercial product. The latter one is a software tool developed on the PC for evaluating user’s health based on the calculated heart rate variability (HRV). The Visual BASIC 6.0 is employed to develop the ECG feature acquisition unit and the USB interface. The developed system supports data analysis, real-time heartbeat display, illustrations of time-domain and frequency-domain ECG, calculation of heart rate variability, and presentation of health evaluation result. Experimental result indicates that the proposed system has the application potential for PC users in health measurement and monitoring.
