A prolonged sinoatrial conduction time (SACT) is one of the electrophysiologic characteristics of sick sinus syndrome. Because conduction from the sinus node to the atrium can not be assessed directly, an indirect method for estimating the SACT was developed by Strauss et al.: the premature atrial stimulation technique. The theoretical basis of the method is reviewed and the use of atrial spontaneous premature beats is proposed to estimate the SACT instead of electrical premature atrial stimulation.
窦房传导时间（SACT）延长是病态窦房结综合征的电生理特征之一。由于无法直接评估从窦房结到心房的传导，Strauss等人开发了一种间接估计SACT的方法：房性期前刺激技术。本文回顾了该方法的理论基础，并提出使用房性自发早搏来估计SACT，而非电刺激诱发的房性期前收缩。
