Amiodarone as a First-Line Therapy for Postoperative Junctional Ectopic Tachycardia

Amiodarone as the first-line treatment was effective in almost half of the patients with postoperative junctional ectopic tachycardia. Higher arteriovenous oxygen saturation difference and lower body temperature were associated with failure of amiodarone therapy, and their presence may suggest more aggressive initial approach consisting of amiodarone combined with hypothermia.
