Asymptomatic Lone Atrial Fibrillation in Pregnant Women

Abstract

We examined 43 pregnant women with paroxysms of asymptomatic lone atrial fibrillation. It was revealed that the increasing of the gestational age leads to increase of number of single, paired and group supraventricular extrasystoles; single and paired ventricular extrasystoles; number and duration of paroxysms of atrial fibrillation. However, the number of extrasystoles and paroxysms of arrhythmia decreased to baseline values after delivery. Thus, it was proved that pregnancy contributes to the increase of paroxysms of lone atrial fibrillation due to the increased influence of modulating components on the triggering extrasystoles. The importance of the method of 24-hour ECG monitoring in the detection of arrhythmia in pregnant women is emphasized.


Keywords: lone atrial fibrillation, extrasystole, pregnancy.
