本文报道46例病窦组和35例对照组患者经食管心房调搏测定窦房结功能的结果,通过应用自主神经阻滞剂前后的比较,估价应用自主神经阻滞剂的必要性,结果发现心得安5—10mg和阿托品2mg同时静注的效果明显优于心得安10mg和阿托品2mg先后静注,初步认为心得安与阿托品宜同时注射。通过应用自主神经阻滞剂测定窦房结功能,并能区分自主神经调节异常与窦房结固有病变引起的窦房结功能不全。本组应用阻滞剂的结果与文献报道的心脏移植后供者心(去神经支配的窦房结)结果相似,提示其作用是完全的。
This article reports 46 cases of sick sinus group and 35 cases of control group by transesophageal atrial pacing determination of the function of the sinus node, by comparing the use of autonomic blockers before and after the evaluation of the necessity of application of autonomic blockers and found that 5mg of propranolol and 2mg of atropine at the same time the effect of intravenous injection was significantly better than propranolol and atropine 2mg intravenous injection of propranolol and atropine presumably at the same time injection. Through the application of autonomic blockers determination of sinoatrial node function, and can distinguish between autonomic nervous regulation and sino-atrial node intrinsic lesions caused by sinus node dysfunction. This group of application of blocker results and reported in the literature after donor heart (denervated sinus node) results are similar, suggesting that its role is complete.
