Abstract：Objective To investigate the influencing factors of fetal arrhythmia and its prognosis, and provide scientific basis for clinical work.Methods The clinical data of fetal electrocardiogram(FECG) were retrospectively studied, which came from pregnant women in hospital as outpatients or inpatients examined from August 2011 to July 2014 our hospital. Further analysis was carried out on data diagnosed with fetal arrhythmia.Results (ⅰ) A total of 67 fetal arrhythmia were detected, with an incidence rate of 0.22%( there were 29 853 deliveries during the study period). Among the 67 cases with fetal arrhythmia, there were 19 cases (28.4%) with fetal tachycardia, 4 cases (6.0%) with fetal tachycardia, 11 cases (16.4%) with fetal arrhythmia, 31 cases (46.3%) with fetal supraventricular premature beat, and 2 cases (3.0%) with fetal ventricular premature beat. (ⅱ) The influencing factors of fetal arrhythmia were mainly cardiac structural abnormalities, fetal distress, and umbilical cord abnormalities, accounting for 26.8%, 20.8% and 17.9%, respectively. (ⅲ) Among 67 cases with fetal arrhythmia, 5 cases received conservative treatment and continued pregnancy after fetal heart rhythm returned to be normal; Four cases were unwilling to take risk and voluntarily chose odinopoeia; Fifty-eight cases of pregnant women were followed up till one week after delivery, among whom neonatus ECG abnormalities were detected in 8 cases, and 50 cases had favorable prognosis. By Fisher exact probability test, it indicated that no statistically significant difference was found in the prognosis of cases with different types of fetal arrhythmia (P=0.165). Conclusion For the diversity of fetal arrhythmia types and influencing factors, individualized therapy and treatment options should be taken according to specific types. There was no statistically significant difference in the prognosis of cases with different types of fetal arrhythmia. It indicates unfavorable prognosis if fetal arrhythmia is accompanied with serious cardiac malformation. Positive clinical intervention is required in this case.
