近十多年来由于临床心脏电生理研究的进展,对阵发性室上性心动过速(PSVT)的发生机制有了较新的认识。由于不同机制所引起的PSVT 无论在临床表现及治疗效果上都有所不同,因此对PSVT 进行新的分型诊断,以代替过去分为房性及结性两类实属必要。但新的分型诊断必须以心脏电生理检查作为依据。我们自1983年来对56例PSVT 病例除常规心电图 In recent ten years, due to the progress of clinical cardiac electrophysiological research, there is a new understanding of the pathogenesis of paroxysmal supraventricular tachycardia (PSVT). Because of different mechanisms caused by PSVT both in clinical manifestations and treatment are different, so the new PSVT classification diagnosis to replace the past is divided into two types of atrial and nun are necessary. However, the new classification of the diagnosis must be based on electrophysiological examination. We have performed routine electrocardiograms on 56 PSVT cases since 1983
