Abstract
A device and method for improving the identification accuracy of fetal heart rate deceleration. The method includes: collecting fetal heart rate data (101); performing baseline identification on the collected fetal heart rate data (102); preprocessing the collected fetal heart rate data (103); performing deceleration identification on the preprocessed fetal heart rate data according to preset deceleration judgment standards and a fetal heart rate data baseline to obtain a decelerated data segment (104); and calculating a deceleration attribute value of each decelerated data segment (105), and outputting the decelerated data segment and calculation result (106). The present invention can effectively eliminate the baseline variation part by employing methods such as the dynamic threshold area method, continuous wave peak detection and composite deceleration detection and so on, and accurately identify each deceleration and the type thereof, avoiding the defects of the existing method, which easily causes large deceleration identification errors but cannot identify continuous deceleration or eliminate baseline variation and cannot identify composite deceleration and so on. The solutio…
