Adenosine is the drug of choice for treating narrow-complex paroxysmal supraventricular tachycardia. It works by temporarily stopping conduction through the AV node, thereby ending re-entry pathways for tachycardia. Diltiazem may also be used, but it is generally reserved for patients who are unresponsive to adenosine or for those with an underlying atrial fibrillation. Dopamine and amiodarone are not typically used as first-line therapy for narrow-complex paroxysmal supraventricular tachycardia.
