对102例阵发性室上性心动过速(PSVT)患者进行电生理检查,结果为窦房折返性心动过速(PST)10例占9.8%,房内折返性心动过速(PAT)3例占2.9%,阵发性房室结折返性心动过速(AVN-RT)SF型PSVT47例占46.1%,持续型AVN-RT 4例占3.9%,房室折返性心动过速(AV-RT)35例占34.3%(其中隐匿性预激5例),不能肯定者3例,占2.9%。可见PSVT发病中以AVN-RT、AV-RT最为多见,它们的鉴别有赖于电生理检查。
Electrophysiological examinations of 102 patients with paroxysmal supraventricular tachycardia (PSVT) showed that sinoatrial reentry tachycardia (PST) accounted for 9.8% of all cases, and room reentrant tachycardia (PAT) 3 Cases accounted for 2.9%, 47 cases of paroxysmal atrioventricular nodal reentrant tachycardia (AVN-RT) SF type PSVT accounted for 46.1%, persistent AVN-RT 4 cases accounted for 3.9%, atrioventricular reentrant tachycardia (AV- RT) 35 cases accounted for 34.3% (including occult pre-excitation in 5 cases), can not be sure in 3 cases, accounting for 2.9%. Visible PSVT in the pathogenesis of AVN-RT, AV-RT most common, their identification depends on the electrophysiological examination.
