1. A 50-year-old patient with intermittent, non-sustained ventricular tachycardia (NSVT) is hemodynamically stable. The ECG reveals an unexpected finding in the beats between the NSVT runs, suggesting Brugada syndrome. Which medication could potentially worsen his arrhythmia if started empirically?

Procainamide
Beta-blocker
Calcium channel blocker

Amiodarone infusion
Urgent synchronized cardioversion
Additional bolus of adenosine
Verapamil infusion
