Giardina等在综合62例婴儿及儿童房室旁道(W-P-W)综合征时曾报道心室预激的心电图图型(δ波)可在童年早期消失。但是,房室旁道的逆行传导在理论上仍可保持完整,并可用以解释这些患者中出现反复发作的快速心律失常。为此,作者对46例反复发作阵发性室上性心动过速或心房扑动-颤动而心电图无心室预激表现的患者进行了研究,证实其中12例有仅能提供逆行传导的房室旁道(隐匿性W-P-W综合征)。12例中男 Giardina et al. Reported that ventricular pre-excitation ECG patterns (delta waves) disappeared early in childhood when combined with 62 W-P-W syndromes in infants and children. However, retrograde conduction of atrioventricular arches remains theoretically intact and can be used to explain recurrent tachyarrhythmias in these patients. To this end, the author of 46 cases of recurrent paroxysmal supraventricular tachycardia or atrial flutter - fibrillation and ECG without ventricular pre-excitation performance of the patients were studied, of which 12 cases confirmed that only provide atrioventricular retrograde conduction Bypass (occult WPW syndrome). 12 cases of male
