Background. The article aims at examining the incidence of premature beats, paroxysms of supraventricular tachycardia and features of anterograde conduction of excitement along the atrioventricular connection in nonpregnant and pregnant women with no complaints and no structural heart disease.
Materials and methods. The authors used Holter ECG monitoring, transesophageal electrophysiological study of hearts.
Results. It was proved that in nonpregnant and pregnant women with premature beats and paroxysms of supraventricular tachycardia there are four types of curves of AB, including continuous, intermittent, continuous with “gap” phenomenon, intermittent with “gap” phenomenon. It was found that in nonpregnant women the continuous type was detected in 80,8 %, intermittent – in 19,2 %. It was proved that, compared to non-pregnant women, in pregnant ones one may witness a decreases of the continuous type from 80,8 to 40,0 % and an increase of the intermittent type from 19,2 to 60,0 % (p < 0,001). It was revealed that the postpartum types of curves do not differ significantly from the curves in nonpregnant women.
Conclusions. In nonpregnant women the most common is the continuous curve type of AV, in pregnant one - the intermittent type, and six months after birth – the continuous one.

beats, supraventricular tachycardia, anterograde conducting, non-pregnant and pregnant women.
