다국어 초록 (Multilingual Abstract)

This paper represents an improved ECG data reduction algorithm which is very useful for real time ECG analysis based-on microcomputer. In order to increase data reduction rate of Turning Point(TP), existing real time data reduction algorithm.
The results obtained from the improved Modified Turning point(MTP) data reduction algorithm applied to three different pattern ECG signals.
(1) The average data reduction rate of MTP algorithm is 67%, which is increased by 17% than that of TP algorithm.
(2) The average percent rms difference(APRD) which is a normalized value that indicates the error between two signals is 9.4% for TP algorithm, while the APRD of MTP algorithm is 6.2% for MTP algorithm. It means that the PRD can be improved by 3.19. Therefore, it gives more excellent resolution than that of TP algorithm.
