ABSTRACT
Objective. To design a portable cardiac monitor system based on the available ordinary ECG machine and works on the basis of QRS parameters. Method. The 80196 single chip microcomputer was used as the central microprocessor and real time electrocardiac signal was collected and analyzed [correction of analysized] in the system. Result. Apart from the performance of an ordinary monitor, this machine possesses also the following functions: arrhythmia analysis, HRV analysis, alarm, freeze, and record of automatic papering. Convenient in carrying, the system is powered by AC or DC sources. Stability, low power and low cost are emphasized in the hardware design; and modularization method is applied in software design. Conclusion. Popular in usage and low cost made the portable monitor system suitable for use under simple conditions.

The Jingluo is a great hypothesis and theory of Chinese traditional medicine. The physical existence of Jingluo phenomena has been proved by many medical practices, but its real mechanism is still unknown. Here is a conjecture about Jingluo: "The essence of Jingluo is in CNS, the lines of Jingluo on soma is only actually a mapping of some strong connection networks in cortex or white matter of brain". Many new modalities of medical imaging like fMRI, PET, SPECT and Mapping MEG can do a good job on functional brain imaging. If we improve their spatial resolution and develop new methods to indicate brain activities, maybe we can unveil the secret of Jingluo.
