Abstract:

Most fetal arrhythmias are benign processes in cardiac embryo development, transient and good prognosis. And persistent fetal arrhythmia or arrhythmia with heart structural defect, fetal edema, can cause perinatal adverse outcome. In this case, persistent supraventricular arrhythmia with fetal edema was treated with digoxin monotherapy, the pregnancy terminated by caesarean section at 36 weeks of gestation and the newborn died 3 days after birth. By reviewing the patient′s general situation and diagnosis and treatment process, summarizing experience and lessons, and strengthening clinicians′ understanding of the disease and its treatment plan, for patients with fetal arrhythmia, perinatal maternal and child monitoring should be strengthened, and individualized treatment plans should be formulated to improve adverse pregnancy outcome.
