Seventy consecutive patients hospitalized before 1 year of age for reentrant paroxysmal atrial tachycardia (PAT) were studied according to the age of onset of arrhythmia making 3 distinctive groups: group I: 10 patients in whom onset of the arrhythmia occurred during foetal life; group II: 39 infants whose arrhythmia appeared during the first month of life and group III consisting of 21 patients in whom tachycardia began between 1 and 12 months of age. The characteristics and the consequences of the arrhythmia as well as the patients' course and the different treatments used were analysed. Foetal tachycardias were characterized by a slower heart rate. Episodes were most often short and repetitive as opposed to post-natal tachycardias which were often prolonged but somewhat unfrequent. Before the age of 3 months the occurrence of heart failure was more frequent. Independently of the age of onset, 43% of patients presented Wolff-Parkinson-White syndrome (WPW), which disappeared spontaneously in 1 out of 3 cases. The existence of WPW syndrome was correlated with late relapses.
对70例1岁前因折返性阵发性室上性心动过速（PAT）住院的连续患者，根据心律失常的发作年龄分为3个不同组进行研究：第一组：10例心律失常在胎儿期发作的患者；第二组：39例心律失常在出生后第一个月出现的婴儿；第三组由21例心动过速在1至12个月龄开始的患者组成。分析了心律失常的特征和后果、患者的病程以及所采用的不同治疗方法。胎儿期心动过速的特点是心率较慢。发作通常较短且反复，与出生后心动过速相反，后者通常持续时间长但不太频繁。3个月龄前心力衰竭的发生率更高。无论发作年龄如何，43%的患者出现预激综合征（WPW），其中三分之一的病例可自发消失。WPW综合征的存在与晚期复发相关。
