经食管心房调搏对室上性心动过速诊断价情的评估

Evaluation of Diagnostic Value of Transesophageal Atrial Pacing in Su-perventricular Tachycardia

研究了53例室上性心动过速(PSVT)病人,比较经食管心房调搏技术与心内电生理检查所测得的各项指标。结果:食管心房调搏技术对房室结双径路(DAVNP)并发房室结折返性心动过速(AVNRT)和隐匿性房室旁道并发房室折返性心动过速(AVRT)敏感性分别为93.5%主87%,特异性均为100%。AVNRT和AVRT的RP'分别为72±15ms和128±17ms(P<0.01)。提示经食管心房结调搏技术对PSVT鉴别诊断具有很高的价值。

53 patients of superventricular tachycardia(SVT) have been studied. The results of transesophageal atrial pacing (TAP) were compared with those of interior cardiac elec-trophysiologic studies. The results showed that, by TAP, the sensitivity of atrioventtricular (A -V)nodal reentry tachycardia(AVNRT) of dual A- V nodal pathwqy (DAVNP) and that of A-V reentry tachycardia(AVRT) of unconcealed WPW Syndrome are respectively 93. 5% and 87%, and that the specificity of the above two was 100% separately;and that the RP’ interval of AVNRT and of AVRT were respectively 72 ± 15ms and 128 ± 17ms(P&lt;0.05). The results indicated that TAP had a high value in the diagnos is of SVT
