Altogether 65 patients with the sinoatrial node weakness syndrome (SANWS) and 48 patients with the heart pain syndrome (control group) were examined for a study of the corrected time of sinoatrial node function recovery (CTSNFR) and the time of sinoatrial conduction (TSAC) before and after medicamentous vegetative blockade (MVB). A considerable increase in CTSNFR and TSAC sensitivity after MVB was noted. In most of the SANWS patients CTSNFR after MVB was increased, TSAC was decreased. Elevated CTSNFR in the SANWS patients was determined by the effect of propranolol and atropine and was noted mainly during atrial stimulation with a high frequency (over 160 imp/min).
总共对65例窦房结功能不全综合征（SANWS）患者和48例胸痛综合征患者（对照组）进行了检查，以研究药物性自主神经阻滞（MVB）前后窦房结功能恢复校正时间（CTSNFR）和窦房传导时间（TSAC）。发现MVB后CTSNFR和TSAC敏感性显著增加。在大多数SANWS患者中，MVB后CTSNFR增加，TSAC降低。SANWS患者CTSNFR升高是由普萘洛尔和阿托品的作用决定的，主要在高频心房刺激（超过160次/分钟）时出现。
