Method and system for processing acceleration activity on fetal heart rate curve

Abstract

The invention relates to a method and system for processing an acceleration activity on a fetal heart rate curve. The method is used for realizing the steps that fetal heart rate data of a user are collected through various collection devices, the collected data are subjected to data rejection to obtain an effective fetal heart rate value, and a fetal heart rate base line is calculated according to the effective fetal heart rate value; the fetal heart rate curve is obtained by preprocessing the fetal heart rate data, furthermore, based on the fetal heart rate base line and the fetal heart curve, judgment of a first acceleration position, adjustment of an acceleration change position, calculation of a local base line value, second acceleration position judgment, calculation of a starting point and an ending point of acceleration change, calculation of a curve change index and judgment of the acceleration activity are performed, the acceleration position, acceleration time and acceleration amplitude of the fetal heart rate curve are obtained; and the acceleration position, acceleration time and acceleration amplitude are displayed through an interactive interface. The method and system for processing the acceleration activity on the fetal heart rate curve has the beneficial effects that the accuracy of acceleration activity identification is improved, and the results of wrong judgment and multiple judgment are reduced.

Description

technical field [0001] The invention relates to a method and system for processing acceleration activities on a fetal heart rate curve, belonging to the field of computer detection. Background technique [0002] In the current obstetrics and gynecology clinic, the research and analysis of fetal heart rate is one of the important links in diagnosing fetal health diseases. Monitor the fetal heart rate during pregnancy for a period of time, such as monitoring the fetal heart rate data for 10 or 20 minutes, and then observe whether the fetal heart rate curve with certain fluctuations is in the normal range of 110BPM to 160BPM; secondly, observe whether there is a heart rate accompanied by fetal movement Acceleration, the number of accelerations accompanied by fetal movement within 10 minutes or 20 minutes, and the number of heart rate accelerations affected by uterine contractions, etc. [0003] At present, the most common way to obtain fetal heart rate data is to use the ultra...

Problems solved by technology

[0009] Algorithm analysis and acceleration activities are based on medical standards such as electronic fetal heart rate monitoring and obstetrics and gynecology. Due to the differences in algorithm processing methods and processing capabilities, the actual clinical use of this technology is also uneven: some misjudgments, The part of the fetal heart rate baseline variation is judged as acceleration; some have multiple judgments, and one acceleration activity that briefly returns to the baseline is judged as two, resulting in more acceleration results; When data changes in more complex situations, the ability of the algorithm to identify acceleration activities is limited, resulting in situations where acceleration activities are not judged
