自1973年 Montoyo 创用经食道非创伤性心房调搏以来,心脏电生理检查在国内迅速开展。经食道心房调搏(TEAP)测定窦房结恢复时间(SNRT)、窦房结传导时间(SACT),从而使窦房结(SAN)的激动形成和传导功能有了较为客观的定量和定性检查指标。但是,单纯 TEAP 测得的 SNRT、SACT 受很多因素的影响,因此影响了对 SAN 功能的判定。作者采用药物双向阻滞前后TEAP 检查方法,观察 SNRT、SNRTc(窦房结恢复时间校正值)、SNRT(?)(房窦结恢复时间指数)、TRT(窦房结恢复总时间)、继发抑制、SACTc(连续刺激法测得窦房传导时间)。结果如下:
Cardiac electrophysiology has been rapidly developing in the country since Montoyo’s creation of transesophageal non-traumatic atrial pacing in 1973. Transesophageal atrial pacing (TEAP) was performed to determine the time to sinus node recovery (SNRT) and the time to conduction (SACT) of sinoatrial node (SAN), so that there was a more objective quantitative and qualitative examination of the activation and conduction of SAN index. However, SNRT and SACT measured by TEAP alone are affected by many factors, thus affecting the determination of SAN functions. The authors used TEAP examination before and after drug bidirectional blockade to observe SNRT, SNRTc (sinus node recovery time correction), SNRT (?) (Atrial sinus node recovery time index), TRT (total sinus node recovery time), secondary Inhibition, SACTc (continuous stimulation measured sinoatrial conduction time). The result is as follows:
