本文对51例应用阿托品后经食道调搏测定窦房结恢复时间。其中22例为病窦患者,29例为功能性心动过缓并作为对照组。病窦患者的SNRT≥975ms,SNRTc≥305ms。对病窦的检出率分别为22/22、20/22,而对照组的29例功能性窦缓患者SNRT和SNRTc测定值均小于上述数值,无一例假阳性。阿托品注射后的SNRT测定对病窦有较好的诊断意义。
In this paper, 51 cases of atropine after transesophageal pacing determination of sinus node recovery time. Among them, 22 were sick sinus patients and 29 were functional bradycardia and served as control group. STI patients with SNRT ≥ 975ms, SNRTc ≥ 305ms. The detection rates of sick sinus were 22/22 and 20/22, respectively. The SNRT and SNRTc values of 29 patients with functional sinus delay in the control group were all less than the above values, and none of them was false positive. SNRT determination after atropine injection has a good diagnostic significance for sick sinus.
