A Case Report on Wolff–Parkinson–White syndrome in Pregnancy

Wolff–Parkinson–White syndrome (WPWS) is a rare congenital pre-excitation syndrome characterised by the presence of an accessory pathway that predisposes to tachyarrhythmia and sudden death. A 26-year-old G4P1L1A2 woman was admitted at 11 weeks of gestation with complaints of headache, vomiting, chest pain and palpitation. ECG elicited supraventricular tachycardia, short PR interval and wide QRS complex. With a reactive non-stress test, the patient was continuously monitored and treated with beta-blockers. Both pregnancy and the WPWS aggravate each other’s tendency to produce arrhythmias. Adequate preparation with fluid preloading and positioning, securing appropriate drugs and emergency equipment, avoidance of tachyarrhythmia and prompt treatment on occurrence is required for the safety of both the mother and the foetus. Prompt diagnosis and rigorous and collaborative team management are very essential to save the patient’s life.
