Abstract
A six-year-old girl with syncope in association with atrial flutter-fibrillation and ventricular tachycardia produced by exercise or emotion is presented. The tachycardias could be reproduced by low-dose isoproterenol infusion and were blocked by high dose propranolol therapy. Catecholamine-induced tachyarrhythmias should be suspected in children with unexplained syncope in association with exercise or emotion.
摘要
本文报告一名六岁女童，其在运动或情绪激动时出现晕厥，伴有心房扑动-颤动和室性心动过速。低剂量异丙肾上腺素输注可诱发心动过速，高剂量普萘洛尔治疗可阻断心动过速。对于伴有运动或情绪激动相关不明原因晕厥的儿童，应怀疑儿茶酚胺诱导的快速性心律失常。
