Correct answer: E — IV amiodarone

In haemodynamically stable monomorphic VT with structural heart disease, IV amiodarone is the first-line antiarrhythmic. Flecainide and verapamil are contraindicated in the setting of structural heart disease (risk of haemodynamic collapse). If the patient deteriorates, synchronised DC cardioversion should be performed.
