自1971年Mandel等首先用心房超速起搏方法测定窦房结恢复时间(SNRT)以估价窦房结(SAN)功能以来,SNRT测定在病窦综合征(SSS)诊断中的价值已逐步为人们所认识,但对其测定方法的许多方面尚有异议。本文就以下几个问题进行初步探讨。一、SNRT矫正指标的选择对照心率与SNRT密切相关,要对不同心率进行比较,必须用基本周期(spontanous cycle longth,SCL)对SNRT进行矫正。但其矫正方法,文献报道各自不一,目前沿用的
Since 1971, Mandel et al first used antrial speeding pacing method to measure the time to sinus node recovery (SNRT) to estimate the function of the sinoatrial node (SAN), the value of SNRT in the diagnosis of sick sinus syndrome (SSS) However, there are still many objections to its method of determination. This article on the following issues for a preliminary discussion. First, the choice of SNRT correction index control Heart rate is closely related with SNRT, to compare different heart rate, the basic cycle (spontanous cycle longth, SCL) SNRT correction. However, its correction method, the literature reported different, currently used
