隨著社會的富足以及進步，大家在豐富的物質生活環境下造成現代人的體重直線上升，同時也造成心血管疾病的患者急速增加以及年輕化。因此一些可攜式醫療電子器材若能常備在家裡讓使用者可以隨時檢查自己的身體。這樣除了可能及早發現問題挽救生命之外，也可以減少由於急救或到醫院檢查之類的社會成本。再加上現今電子業在技術上的突破以及進步，這使的低價高精確度的醫療電子器材的實現成為可能。也唯有低價高精確度的裝置才有可能大量普及。
本論文在研究低價高精確度的可攜式心電圖機之相關技術與實現，技術方面將電級片由人體皮膚表面取得微弱的差動信號經由濾波以及放大處理之後可以得到完整的心電圖波形，同時經由MCU做A/D轉換後經由LCD輸出以方便使用者觀察或判讀量測到的心電圖波形。整個系統由單一5V電池供給就可以完成。

With the wealth of society and progress, everyone in the rich material life conditions caused by the weight straight up modern, but also caused the rapid increase in cardiovascular disease patients and younger. Therefore, some portable medical electronic equipment if standing at home so that users can always check your body. In addition to early detection of problems that may save lives, but also can reduce the emergency or to the hospital like the social costs. Coupled with today's electronics industry, the technological breakthroughs and advances, which makes low-cost high-precision medical electronics equipment possible to achieve. And only low-cost high-precision devices is possible a lot of popularity.
In this paper the study of low-cost high-precision portable ECG machine and implementation of related technologies, technology will power-level film made from the skin surface through a weak differential signal after filtering and amplification process can be complete ECG waveform, At the same time by the MCU in a / D conversion via the LCD output to user-friendly interpretation of observed or measured ECG waveform. The entire system from a single 5V battery supply can be completed.
