Apparatus and method for automatically identifying fetal heart rate baseline

摘要

An apparatus and method for automatically identifying FHR baseline includes collecting FHR data within a preset duration to obtain an FHR data sequence h′(n); preprocessing the collected FHR data sequence h′(n) to obtain a corresponding FHR data sequence during the preprocessing; selecting a primary dominant peak value according to the frequency distribution of the corresponding FHR data sequence during the preprocessing; and identifying a dynamic baseline according to the corresponding FHR data sequence and the primary dominant peak value during the preprocessing to obtain the dynamic baseline, and display and print the dynamic baseline. The apparatus and method effectively prevents the impact caused by regular change of the FHR to the baseline solution, and accurately reflects the FHR baseline and changes thereof of a fetus under different conditions.
