MRCP2-0402

A 55-year-old man presents to the Emergency department complaining of severe central chest pain. Upon examination, the 12-lead ECG shows inferior ST segment elevation, indicating an acute inferior myocardial infarction. Thrombolysis is initiated based on the ECG findings.

However, thirty minutes later in the coronary care unit, the patient develops complete atrial and ventricular dissociation. Despite this, his blood pressure remains stable at 120/80 mmHg. Ten minutes later, he experiences intermittent runs of ventricular tachycardia (VT), which cause his blood pressure to drop significantly to 85/65 mmHg.

Fortunately, his blood pressure stabilizes over the next ten minutes at 110/75 mmHg, and no further episodes of ventricular tachycardia are recorded.

What is the best immediate management for this patient?
