Pregnancy outcomes among patients with inappropriate sinus tachycardia

Abstract

BACKGROUND: About one percent of the population is affected by inappropriate sinus tachycardia. Little is known about this condition during pregnancy. Our objectives were to get a deeper understanding of the natural course of inappropriate sinus tachycardia in pregnancy and to investigate maternal and foetal outcomes.

METHODS: Forty-two pregnant women with symptoms consistent with inappropriate sinus tachycardia were included in this observational cohort study and compared to 42 control pregnant women.

RESULTS: No significant difference was found in age, twin pregnancy, diabetes, blood pressure, and hemoglobin level while the gravida of the inappropriate sinus tachycardia group was significantly lower than control (p-Value=0.002). The symptoms resolved in the majority (83%) of cases within 2 weeks of delivery. Pregnant patients with inappropriate sinus tachycardia have higher unscheduled hospital visits (38.1 vs 9.5%; p-Value=0.002) and induction of labor (45.2% vs 23.8%; p-Value=0.039).

CONCLUSION: Hospital visits and induction of labor were higher in pregnant patients with inappropriate sinus tachycardia which may not be necessary with more emphasis should be on empathic care and patient education.
