Clinical Characteristics of Cardiac Arrhythmias In Pregnant Women

Abstract

Introduction: Cardiac arrhythmia often occurs in the gestational period of pregnant women, contributing to the development of complications of pregnancy, childbirth and perinatal pathology, which requires a more thorough examination of pregnant women and antiarrhythmic treatment, which in turn increases the risk of complications pregnancy and childbirth. Many types of arrhythmias occur in women without structural damage to the cardiovascular system. The aim is to study the occurrence of cardiac rhythm disturbances in healthy pregnant women, depending on the gestational age, the number of previous pregnancies, infectious diseases during pregnancy, and arrhythmia analysis, which required antiarrhythmic treatment. Materials and methods: Retrospectively 60 individual cards of pregnant women were studied. An ECG monitoring was performed to identify the arrhythmia. Results: Among the arrhythmia were: supraventricular and ventricular extrasystoles, unstable paroxysmal tachycardia. All cases of arrhythmia were without lengthening QT interval. Sinus tachycardia was significantly more common in combination with anemia. Heart rhythm disorders are associated with emotional excitement. Conclusions: Most violations of the heart rate occurred in the second trimester of pregnancy. With concomitant anemia, sinus tachycardia is significantly more common, and sinus bradycardia is associated with an enlarged uterus in compression of the inferior vena cava. With the increase in the number of pregnancies, the risk of heart rhythm disturbances increases. However, the past infectious diseases of the bronchopulmonary system during pregnancy did not significantly affect the occurrence of rhythm disturbances. The appointment of antiarrhythmic drugs was observed in all pregnant women whose cards were included in the study.

Successful Management of Intractable Supraventricular Tachycardia in Pregnancy

“…Approximately, there is an increase of 10 beats per min in the resting pulse rate during pregnancy. Marked changes in the maternal heart rate occur in the second trimester of pregnancy and the increase in gravidity imposes an increased risk of cardiac disturbances [3,4]. The blood volume increases by an average of 50% markedly from the latter half of the first trimester.…”

Catheter ablation for tachyarrhythmias during pregnancy

“…This might be explained by a higher incidence of new-onset arrhythmias in the second trimester during pregnancy. Afanasiuk et al [ 66 ] also observed a higher incidence of new-onset arrhythmias in the second trimester. They explained this trend as a result of compression of the cardiovascular structures by the enlarged uterus in the second trimester.…”
