Abstract:
Based an ordinary ECG, this paper deals with a portable monitor system able to measure the values of QRS. With a liquid crystal display (LCD), this monitor is suitable for China's special condition. Besides developing the overall scheme of the system, this paper also performs the designs for the hardware and software. The 80196 single chip microcomputer is taken as the central microprocessor to process and analyze the realtime ECG signals. With the performances of the ordinary monitor, this monitor also has such functions as arrhythmia analysis, HRV analysis, alarm, self-freeze and paper self-advance. Being convenient to carry, this monitor can be powered by alternate current (AC) or direct current (DC). Stability, low power consumption and low cost are emphasized on in the hardware design and structured design is applied to the software design. With a high versatility and a low cost, this monitor has a valuable reference to China's monitor.
