Abstract

The invention discloses a multi-lead joint detection intelligent fetal electrocardiogram detection method and system. The method includes the steps: a, acquiring a group of multi-channel maternal electrocardiogram signals J1, J2,...Jm, and acquiring another group of maternal and fetal multi-channel mixed electrocardiogram signals V1, V2,...Vn; b, determining the optimal maternal electrocardiogram signal Jk among the maternal electrocardiogram signals J1, J2,...Jn, and performing complex wave QRS (quantum resonance detection) for the optimal maternal electrocardiogram signal Jk to obtain complex wave QRS results; c, respectively extracting corresponding fetal electrocardiogram signals V'1, V'2,...V'n from the mixed electrocardiogram signals V1, V2,...Vn; d, determining the optimal fetal electrocardiogram signal V'L among the fetal electrocardiogram signals V'1, V'2,...V'n, and performing complex wave QRS for the V'L to obtain real-time fetal heart rate and complex wave QRS width indexes by calculation. Fetal electrocardiogram signal extraction stability, robustness and noise sensitivity can be effectively enhanced, and real-time correct detection success rate of the fetal electrocardiogram signals is increased.

Description

technical field [0001] The invention belongs to the technical field of fetal electrocardiogram detection, in particular to an intelligent fetal electrocardiographic detection method and system for multi-lead joint detection. Background technique [0002] Fetal ECG monitoring is conducive to timely detection of fetal hypoxia, umbilical cord entanglement and other fetal pathological conditions during pregnancy, and early measures to ensure fetal health and reduce perinatal fetal morbidity and mortality. The fetal ECG detection method obtained from the surface of the maternal abdominal wall is popular among medical workers and pregnant women because of its convenience and non-invasiveness. [0003] How to effectively extract the fetal ECG signal from the mixed ECG signal of the pregnant woman's abdominal wall is a major difficulty: (1) The fetal ECG signal is very weak when it passes through the amniotic fluid, uterine wall, etc. and finally reaches the maternal abdominal wall;...
