There are few data of arrhythmia characteristics and perinatal outcomes in patients without any structural heart disease. Purpose To describe the clinical peculiarities, pregnancy course and characterize outcomes. Methods A total of 99 pregnant without structural heart disease with arrhythmia was included, aged: 29.05±5.37years with a mean gestation age 22.7±7.29 weeks. Clinical characteristics, obstetric and neonatal outcomes were determined. Results The most common reported arrhythmias were supraventricular tachycardia (n=46; 46.5%) and premature contractions (n=36; 36.3%). Advanced heart block (n=9; 9.1%) and ventricular tachycardia (n=8; 8.1%) were rare during pregnant with structurally normal heart. The 56% of arrhythmia cases among the examined patients first occurred during current pregnancy. Studying the peculiarities of arrhythmia manifestations, it was determined that in the I trimester of pregnancy the disease symptoms appeared in 11% of the examined women, in the II trimester – in 59%, in the III trimester – in 31%. In the clinic, the most common symptoms of arrhythmia were palpitations (62.6%), general weakness (59.6%), dyspnea (38,4%) and dizziness (29.9%). Pregnancy course was benign in the majority of cases. Termination of pregnancy was in three cases (3%) – in one case due to extracardial cause, in two cases due to life threatening course of ventricular tachycardia. Premature birth was in 2 cases (2.02%). In 75% of pregnancy was vaginal delivery, in 25% - cesarean section. Preeclampsia was in 2 cases (2.02%). There were 99 live births without maternal and fetal mortality. Conclusions In pregnant women with no structural heart disease supraventricular tachycardia and premature beats are most common. Majority of patients have good course of pregnancy and outcomes.
