[Development of a portable ECG monitor based on TMS320VC5402].
OBJECTIVE
To develop a portable ECG monitor with top performance.


METHODS
The hardware system and control program were designed basing on a digital signal processor TMS320VC5402. An algorithm of arrhythmia detection was embedded.


RESULTS
Four types of arrhythmia could be detected. Seven sections of 64 k-byte ECG data could be stored and the collection time of each segment was marked. The ECG data recorded could be sent to the hospital via either digital or analog method. With low power consumption and rechargeable Li+ battery, this monitor could work continuously.


CONCLUSIONS
The monitor meets the design requirements and possesses excellent practicability.
