condition in is one deceleration group or continuous deceleration groups and the number of the decelerations is analyzed with the continuous peak inspection algorithm in the next step if it does not meet the deceleration standard is the baseline variation part with this step the deceleration part and the baseline variation part may be distinguished 1043 analyzing the number of continuous decelerations of the deceleration sequence segment as to each fetal heart rate sequence segment here it may be the process analyzed with the continuous peak inspection algorithm is as follows the continuous sequence segment of which the deviation value of the corresponding baseline is not more than the threshold r1 is sought in the segment if there is no sequence segment all deviation values exceed the threshold r1 meeting such condition the is one deceleration if there is a sequence segment meeting such condition recording as the its adjacent segments are facilitated to be continuous and analyzed whether they meet the deceleration standard if the deceleration standard is met the continuous data segment becomes one deceleration and the subsequent segment data are analyzed according to the deceleration standard continuously again otherwise the baseline incorporates the segment until all of the segments are incorporated with this step continuous deceleration is identified fig7 is an effective diagram of deceleration identification the fetal heart rate curve part in the square frame in the figure is the baseline variation part the curve segment part designated with the.
