Supraventricular tachycardia in pregnancy.

Treatment of paroxysmal supraventricular tachycardia during pregnancy is necessary to protect both mother and the fetus. In case of hemodynamic deterioration, pharmacological treatment is the treatment of choice. There are limited reports for the safety and efficacy of verapamil use in pregnancy for treatment of paroxysmal supraventricular tachycardia. Numerous case reports and a retrospective study suggest that adenosine is safe and effective for these kinds of arrhythmias.
