至今尚无一简便、可靠的窦房结功能测试方法。目前应用的窦房传导时间(SACT)窦房结恢复时间(SNRT)和其校正值(CSNRT)及继发性间歇测定,都是在直接右房调搏下获得的,因此不能成为窦房结功能检查的常
To date, there is no simple and reliable method for testing sinus node function. The currently used sinus node conduction time (SACT) sinus node recovery time (SNRT) and its correction value (CSNRT) and secondary intermittent measurements are obtained with direct atrial tachycardia and therefore can not be the sinoatrial node Often check the function
