Age-related Changes of the Normal People's Sinoatrial Node Function Meansuration

Objective To observe the change of sinus node recovery time(SNRT) and correct sinus node recovery time (CSNRT), In order to know the rule of age-related changes of CSNRT. Methods Normal people are chosen and divided into three groups. Esophagus electrode is inserted, count SNRT and CSNRT. Results With aging, the CSNRT of three groups people have no difference. Conclusion With aging, the normal people’s CSNRT remain unchanged who have not been pharmacologic autonomic blockade.
