Paroxysmal supraventricular tachycardia in pregnancy: A case report

Paroxysmal supraventricular tachycardia (PSVT) is a clinical syndrome characterized by regular tachycardia with sudden onset and termination that includes atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reentrant tachycardia (AVRT), and focal atrial tachycardia (AT). PSVT is one of the most common types of arrhythmia during pregnancy, and pregnancy itself is a risk factor for PSVT exacerbation. Managing SVT in pregnancy is challenging, given the increased risk of pregnancy morbidity and fetal defects, as well as the potential side effects of antiarrhythmic drugs on the fetus. Here we present two cases of PSVT in pregnancy with the main focus on the management in the acute phase.
