Depression evaluating system and method based on heart rate variability analytical method

Abstract

The invention discloses a depression evaluating system and method based on a heart rate variability analytical method, particularly a depression evaluating system and method in a perinatal period. The depression evaluating system comprises a data storage module used for storing electrocardio and pulse wave signals, a peak detecting module used for acquiring a peak point sequence of recording data, a data correcting module used for acquiring sinus beat NN interval sequence, a heart rate variability curve acquiring module used for acquiring a heart rate variability curve, an HRV analyzing module conducting time domain analysis, frequency domain analysis and nonlinear analysis, a feature parameter selecting module used for selecting a feature parameter from HRV parameters, a modeling module used for obtaining a perinatal period depression classification model, and a model applying module used for inputting the data of a testee into the classification module to obtain a depression degree. By means of the depression evaluating system and method based on the heart rate variability analytical method, degree quantitative evaluation of perinatal period depression is achieved, a scientific research method of the depression based on the technical field of physiological information examination is enriched, a test is simple and practicable, medical resources can be effectively saved, and good clinical practicality is achieved.

Description

technical field [0001] The present invention relates to a computer-aided diagnosis technique, in particular to an evaluation system and method for depression based on a heart rate variability analysis method Background technique [0002] Pregnancy and childbirth are major experiences in a woman's life. Physiologically, a series of major changes in various important organs of the body, sex hormones and related hormones must be experienced from pregnancy to postpartum; psychologically, one must adapt to changes in work, family and colleagues. , to care about the healthy growth of newborns, to take into account economic arrangements, etc.; these complex changes and the stimulation of other adverse factors can induce perinatal depression. Maternal depression often begins during pregnancy, especially from the third trimester to one year after delivery, so the depression that occurs during this special period is called perinatal depression. According to research conducted by the ...

Problems solved by technology

[0003] 1. The efficiency of scale testing and psychological consultation is low, which cannot satisfy the current large and growing population to be screened

[0004] 2. The scoring results of the scale cannot accurately reflect the psychological status of the testers, and there may be cases of subjective concealment of the condition

[0005] 3. Scores from a single rating scale cannot be used to diagnose depression
