Characteristics of CTG and pregnancy management of fetal extrasystole / 中国实用妇科与产科杂志

ABSTRACT

OBJECTIVE: To explore the characteristics of CTG(cardiotocography)and discuss pregnancy management of fetal extrasystole.METHODS: It's a retrospective analysis of women who gave birth in May 2011-March 2018 in PekingUniversity Third hospital.A total of 13 cases were diagnosed as fetal extrasystole through echocardiography or M type ultrasound.The characteristics of CTG,delivery weeks,delivery mode,neonatal arrhythmia diagnosis and treatment weresummarized.RESULTS: In 13 cases,except 2 cases with normal CTG,the others showed that normal fetal heart raterhythm and deceleration alternately appeared,but it was different from hypoxia-induced deceleration.Eight of 13 cases underwent cesarean section,and 4 of these cases were with fetal arrhythmia or fetal distress as an indication.All neonates were alive.One case turned into supraventricular tachycardia,which resolved after receiving medicine.For the other cases,the ECGs resolved or returned to normal within two weeks after the birth.CONCLUSION:s The most common type of extrasystole is atrial extrasystole.When premature beats are not transmitted,we call it blocked atrialextrasystole,which causes deceleration.If there is no heart structure abnormality and heart failure,vaginal delivery canbe performed under closely monitoring.
