本文系统地估价阿托品对正常窦房结和心房的作用,对17例无窦房结疾病患者的心脏电生理学进行研究。全部病例窦房结恢复时间正常(<1680毫秒),计算的窦-房传导时间正常(<152毫秒)、P-A 间期正常(<45 This article systematically evaluates the effects of atropine on normal sinus node and atrium, and investigates cardiac electrophysiology in 17 patients without sinus node disease. The sinus node recovery time was normal (<1680 ms) in all cases, the calculated sinus-atrial conduction time was normal (<152 ms), and the P-A interval was normal (<45
