室上性心动过速(SVT)为一常见的快速性心律失常.近几年来,通过心脏腔内心电图记录,希氏束电图,心内膜标测和程控起搏等临床电生理学的研究,对阵发性室上性心动过速(PSVT)产生机理有进一步了解,现将有关问题阐述如下.
Supraventricular tachycardia (SVT) is a common tachyarrhythmia. In recent years, clinical electrophysiological studies such as intracardiac electrocardiography, His bundle, endocardial mapping and programmed pacing , On the pathogenesis of paroxysmal supraventricular tachycardia (PSVT) have a better understanding, the relevant issues are described below.
