A 39-year-old man presented to hospital complaining of palpitations. He felt nauseated and faint but did not have any chest pain or breathlessness.

He had been diagnosed with Wolff-Parkinson-White syndrome two years previously and had frequent attacks of palpitations that were usually terminated by carotid sinus massage which he performed himself. However, on this occasion carotid sinus massage had failed to terminate the palpitations.

He had a past history of asthma, treated with salbutamol and budesonide inhalers. His only other past history was of a fractured femoral shaft following a road traffic accident three years previously. He was a non-smoker and had no family history of ischaemic heart disease.

On examination he appeared well. His blood pressure was 130/75 mmHg and pulse 160 beats per minutes. His heart sounds were normal and chest clear on auscultation. Abdominal and neurological examinations were unremarkable.

The 12-lead ECG showed a supra-ventricular tachycardia with a rate of 160 beats per minutes.

What is the best treatment that should be given to stop the SVT as carotid sinus massage has been ineffective?
