Abstract
We report a case of Wolff Parkinson White syndrome in 22 year old parturient posted for elective lower segment caesarean section. Patient had 3 episodes of paroxysmal supraventricular tachycardia .Electrophysiological study confirmed diagnosis of WPW syndrome .and radiofrequency ablation carried out.Subarachnoid block was administered to avoid polypharmacy and noxious stimuli of laryngoscopy and intubation.Anaesthetic management is challenging as malignant arrythmias like AVRT in form of paroxysmal supraventricular tachycardia,atrial fibrillation or ventricular tachycardia may occur anytime in perioperative period. It’s important to know correct pathology and management modalities to prevent adverse outcome.
