窦房结功能不全(SND)患者的SVT自发终止或经治疗终止后。常出现长时间的窦性静止。这一现象实际上就是快—慢综合征患者症状的常见原因之一;而心房超速起搏后的SNRT(SNRT—P)可认为是SVT自发终止后的SNRT(SNRT—S)的一种实验模型。鉴于SNRT测定已成评价窦房结功能中较为可靠及常用的一项诊断方法,本文的目的是在于对比SNRT—P与SNRT—S间的相互关系及其在SND诊断中的价值。
SVT in patients with sinus node insufficiency (SND) spontaneously terminated or after termination of treatment. Sinus often appear for a long time. This phenomenon is in fact one of the common causes of symptoms in patients with fast-slow syndrome; SNRT (SNRT-P) after atrial pacing is considered to be an experiment of SNRT (SNRT-S) after spontaneous termination of SVT model. Since SNRT has become a more reliable and commonly used diagnostic method for evaluating sinus node function, the purpose of this paper is to compare the correlation between SNRT-P and SNRT-S and their value in the diagnosis of SND.
