Ans. D. Wolff-Parkinson-White syndrome
Tachyarrhythmia, delta waves on ECG (slurred upstroke of QRS complex), and clinical manifestations point towards a diagnosis of WPW syndrome. Dystachyarrythmia ( supraventricular )occurs because of accessory conduction pathways around the AV groove called ‘the bundle of Kent’.Hemodynamically unstable patients must receive urgent electrical cardioversion. Stable patients can be treated with amiodarone, procainamide, adenosine, and vagal maneuvers
