Initial 12 mg Versus 6 mg Adenosine for Supraventricular Tachycardia in the Emergency Department

This study aimed to compare the efficacy and safety of initial doses of 12 mg versus 6 mg of adenosine for converting sinus rhythm in patients with supraventricular tachycardia (SVT) in the emergency department. The results indicated that the 12 mg dose significantly improved the rate of successful first-dose conversion (83.1% vs. 52.1%) without increasing adverse effects, suggesting it may be a more effective treatment option for SVT.
