小儿窦房结电图的描记与窦房传导时间的测量

SINUS NODE ELECTROGRAM AND THE MEASUREMENT OF SINOATRIAL CONDUCTION TIME IN CHILDREN

本文描记３０例（男１３例，女１７例，年龄８～１４岁）窦房结功能（ＳＮＦ）正常小儿的窦房结电图（ＳＮＥ），以探讨ＳＮＥ在小儿科的应用价值及其特点。结果：２７例成功，３例失败，成功率９０％。直接测定窦房传导时间（ＳＡＣＴｄ）为５２±２０ｍｓ，与成人组（２１例）比较，小儿组显著为短（Ｐ＜０．０１）。其正常上限为９０ｍｓ。表明不能用成人正常值标准来评定小儿ＳＮＦ；描记ＳＮＥ测定ＳＡＣＴｄ是评价小儿ＳＮＦ的一项有价值的客观指标。

The Sinus node electrogran(SNE),on which direct sinoat-rial conduction time(SACTd)could be measured,was recorded in 30 children without sick sinus syndrom(SSS)(aged 3 14 year,13 boys and 17 girls).27 of 30 were successful(90%).The SACTd from SNE was 52±20 ms which was significantly shorter than those in adults with-out SSS (21 cases).The upper limit of SACTd was 90 ms in this group of children.It is concluded that the measurement of SACTd is a valuable method for evaluation of sinus node function in children,
