Abstract Objective To study the effect of fetal electrocardiogram combined with echocardiography for the improvemet of the diagnostic accuracy of pre fetal contractions. Methods Those prenatally diagnozed as Pre fetal contraction by fetal electrocardiogram (FECG) and fetal echocardiography (FUCG) were selected as the research subjects. the consistency of the two detection methods and their sensitivity and specificity for the diagnosis of pre fetal contractions were evaluated. Results FECG findings showed that pre systole accounted for 36.8% of fetal arrhythmias, and FUCG showed premature contraction accounted for 35.5% of fetal arrhythmias, and the consistency of the two methods was 0.972; The sensitivity and specificity of FECG combined with FUCG in the diagnosis of supraventricular premature contractions were 95.95% and 89.17% respectively, The sensitivity and specificity of ventricular premature contraction were 93.55% and 96.50%, respectively. Conclusion There was good agreement between FECG and FUCG in determining pre fetal contractions; To judge the nature of pre contraction, FECG combined with FUCG test can make up for their deficiency so as to improve the accuracy of fetal pre systolic judgment.
