Treatment of intractable incessant tachycardia in children with Amiodarone / 临床儿科杂志

ABSTRACT

Objective To improve the understanding of Amiodarone in the treatment of intractable incessant tachycardia in children. MethodsData of 80 patients with intractable incessant tachycardia treated by Amiodarone were summarized. Among them 52 were male,38 were female,and average age was 2.5 years old. ResultsAmiodarone reduced heart rate effectively, with about 90% effective. Simultaneously, it could convert tachycardia into sinus rhythm and succeeded 67% in atrial tachycardia, 92% in paroxysmal supraventricular tachycardia,89% in junctional ectopic tachycardia, 56% in ventricular tachycardia respectively. Use of small dosage of β-receptor blocker together with Amiodarone showed synergy. Hypotension and bradycardia are the main side effects. ConclusionsToo rapid and sustained tachycardia can lead, to hemodynamic disorders and cause heart failure, it requires urgent and adequate treatment. Amiodarone can be used to treat different kinds of intractable incessant tachycardia, and is safe and effective in patients with relatively stable hemodynamis.
