Wolff–Parkinson–White (WPW) is a rare congenital arrhythmia that could result in peripartum cardiomyopathy. This condition could be managed by medical treatments or ablation treatments. In this report, we presented a 14-year-old pregnant girl with initial signs of syncope and palpitation, who was later diagnosed with WPW-induced peripartum cardiomyopathy. The baby was successfully delivered at 32 weeks gestational age, and the patient received a beta-blocker as the main treatment strategy. We recommend that a proper cardiology and gynecology care is critical in providing the best prognosis.
