Q: For patients with symptomatic Nonsustained Ventricular Tachycardia (NSVT), the first line of treatment is? 

A) Beta Blocker (BB)
B) Calcium Channel Blocker (CCB)
C) Amiodarone
D) Catheter ablation


Answer: A

 Beta blockers(BB) are usually good to control NSVT. In case if patient doesn't respond to BB, CCB (either verapamil or diltiazem) is the second line of treatment. Antiarrhythmic medications e.g. amiodarone should be used as a third line of treatment. Catheter ablation remains a last resort. To add, patients who have NSVT with congestive heart failure (CHF) may become a candidate for the automatic implantable cardioverter-defibrillator(AICD)
