The physiological changes during pregnancy predispose female of new-onset or recurrent arrhythmia. Supraventricular arrhythmia is that the commonest sort of arrhythmia during pregnancy and, although often benign in nature. We describe a complex case of supraventricular arrhythmia during pregnancy and review the currently available literature. In pregnancies complicated by arrhythmia, a follow-up and both maternal and fetal monitoring during pregnancy, delivery and post partum should be made. Diagnostic modalities should be used as in non-pregnant women. All antiarrhythmic drugs cross the placenta, but when necessary, medical treatment should be used.

Electrical cardioversion is safe during pregnancy, and electrophysiological study and catheter ablation sometimes performed in selected patients, preferably with zero-fluoroscopy technique. Sometimes, delivering the fetus (if viable) is that the best therapeutic option.
