We have reviewed the records of 65 children with paroxysmal supraventricular tachycardia (PST) without congenital heart disease followed a mean of 4 years, with a total of 121 episodes. PST appeared before 6 months of age in 42 (64.6%) children. Thirteen patients (20%) had a present factor which might predispose to PST in 66.2% of the patients who were younger than 6 months of age, and in only 4.3% of those over 6 months. Wolff-Parkinson-White syndrome was present on surface ECG during sinus rhythm in 26.1% of children younger than 6 months, and in 39.1% of those over 6 months. Digoxin was the initial treatment in 84.3% of the episodes with a success rate of 75% when were employed alone and of 84.2% when were employed in combination of quinidine. PST recurred at least once in 35 children (53.8%), the 90% within three months of the first episode. All patients were alive and 63 (96.9%) doing well. One patient developed cerebral anoxia and now has hemiparesia and another patient has incessant PST. We conclude that children with PST without congenital heart disease and without delay in diagnosis had a good outcome.
我们回顾了65例无先天性心脏病的阵发性室上性心动过速（PST）患儿的记录，平均随访4年，共发生121次发作。42例（64.6%）患儿在6个月龄前出现PST。13例患者（20%）有一个可能诱发PST的因素，在6个月龄以下的患者中，该因素在66.2%的患者中存在，而在6个月龄以上的患者中仅占4.3%。6个月龄以下的儿童中，26.1%在窦性心律时体表心电图显示有预激综合征，6个月龄以上的儿童中这一比例为39.1%。84.3%的发作最初采用地高辛治疗，单独使用时成功率为75%，与奎尼丁联合使用时成功率为84.2%。35例患儿（53.8%）至少复发过一次，90%在首次发作后3个月内复发。所有患者均存活，63例（96.9%）情况良好。1例患者发生脑缺氧，现患有偏瘫，另1例患者有持续性PST。我们得出结论，无先天性心脏病且诊断无延迟的PST患儿预后良好。
