本系統由類比訊號處理模組、數位訊號取樣模組、本地端即時顯示模組與遠地端即時顯示模組所組成。在類比訊號處理模組中，本系統採用運算放大器來實現放大與濾波電路。在數位取樣模組中，本論文採用了德儀的MSP430F149微處理器，其包含了一個ADC模組，可以將心電圖的訊號數位化，並將轉換後的心電圖數據，透過UART Port傳給可攜式的儀器或個人電腦。本地端電腦透過Com Port接MSP430F149所傳來的心電圖數據，並使用TCP/IP的協定將心電圖數據經由網路傳給遠地端的電腦。遠地端電腦可以安裝在醫院中，所以病人只要待在家中，在醫院中的專業醫生便可觀察病人的心電圖數據。

　　The System consists of analog signal process module
，digital signal sample module，local terminal real-time display　module and remote terminal real-time display module. In the System，we use the operation amplifier to design amplifier and filter circuit in the analog signal process module. A TI’s MPU Product，MSP430F149 is used in the digital signal sample module. The adopted MPU contains an ADC module. So the MPU can sample the ECG signal and transferred the converted data via the UART Port to the Portable Instrument or the Personal Computer. The local terminal computer can receive the ECG data from MSP430F149 via the com port. And then we can use TCP/IP protocol to transmit the ECG data to the remote terminal computer via the internet. The remote terminal computer can be installed in the hospital. So the professional doctor can observe the patients’ ECG data in the hospital while the patient stays at their home.
