Abstract
BACKGROUND: Paroxysmal supraventricular tachycardia (PSVT) is a common arrhythmia. However, its incidence and time course in pregnant women are unclear. This study was conducted to determine the incidence of PSVT in pregnant women by trimester. METHODS: From 2001 to 2012, all pregnant women in Taiwan were monitored for PSVT events. Women who visited the emergency department or were admitted for symptomatic PSVT were enrolled in this study, and those with congenital heart diseases were excluded. RESULTS: A total of 2,387,588 pregnancies (1,623,596 mothers) were analyzed. For the women with no previous history of a PSVT event, the incidence rates of symptomatic PSVT were 15, 33, and 60 per 100,000 pregnancies during the first, second, and third trimester, respectively. For the women with a previous history of PSVT, the incidence rates were 5625, 9525, and 11526 per 100,000 pregnancies, respectively. Most PSVT events occurred during the third trimester. CONCLUSIONS: In this Taiwanese cohort of pregnant women there was a stepwise increase in the incidence of symptomatic PSVT, which peaked during the third trimester. A past history of PSVT was associated with a higher risk of recurrence during pregnancy. We suggest that clinicians should be aware of this trend. Prompt management of PSVT events may prevent maternal and fetal complications.
