摘要

经食道心房调搏测定102例正常儿童的窦房结功能

首次应用植物神经阻滞剂（普奈洛尔0.1mg/kg

阿托品0.02mg/kg）进行对照测定。本组在用药后SCL

SNRT

CSNRT

SNRTI均较用药前减小

差异均有显著意义（P<0.01）;SCL与SNRT呈高度正相关（用药前r=0.8573

用药后r=0.8718）。提出儿童SNRT正常范围估计方法及标准:常规测定为SNRT=1.15SCL+300ms

应用阻滞剂后为SNRT=1.56SCLms为了排除植物神经张力的影响

应用阻滞剂复测对确诊病态窦房结综合征十分必要

Abstract

Transesophageal atrial pacing was performed for evaluation sino-atrial node function in 102 normal children aged 2-15 years. These cases were evaluation again to make a controlled study after autonomic nerve blockade with propranolol(0.1mg/kg)and atropin(0.02mg/kg). In the group

values of SCL

SNRT

CSNRT

SNRTI declined significantly after autonomic blockade comparing with that before(P<0.01) .There was a highly positive correlation between SCL and SNRT(r = 0.8573 pre-medication and r = 0.8718 post-medication).Based on this fact

we suggest that SNRT = 1.15 SCL + 300ms(pre-medication)and SNRT = 1.56SCL ms (post-med-ication)be used as the equations to calculate normal value of SNRT in children.Because of the influence of autonomir nervous tension

it is nesessary to pace again following autonomic blockade administration for a definitive diagnosis of sick sinus syndrome
