小儿先心病心电图P波、QRS波时限、振幅与左房和肺动脉压力的相关分析

CORRLATION ANALYSLS OF RELATION BETWEEN THE TIME LIMIT OF P WAVE AND THE AMPLITUDE VIBRATION OF QRS WAVE AND LEFT ATRIAL AND PULMONARY ARTERIAL PRESSURE IN CHILDREN’S CONGENITAL HEART DISEASES

小儿先心病术后左房压和肺动脉压力的监测在ＩＣＵ中十分重要。心电图是诊断和评价心脏疾患的常用方法。本文分析了３２例小儿先心病手术前后（伴肺动脉高压１６例）６个肢体导联心电图中Ｐ波和ＱＲＳ波时限总和及振幅总和与左房、肺动脉压力的关系。结果表明两者均有良好的相关性（ｒ＝０．８５～０．８８，ｒ＝０．７４～０．，Ｐ＜０．０１），该法简单、方便，可广泛开展，尤其在术后未放置ＰＡ和ＬＡ管或在ＩＣＵ中已拔除ＬＡ和ＰＡ管以后更有价值。

he monitoring of left atrial and pulmonary arterial pressure after operation ofchildren’S congenital heart diseases is importment in ICU. Electrocardiography(ECG)is a routine way to diagnose and evaluate cardiac diseases.This paper retrospectivelyanalyzes the relation between summation of time limit of P wave and amplitude ofvibration of QRS wave in six limb leads and pressure of left atrial and pulmonaryartery in 32 cases of children’s congenital heart diseases(in which,16 cases withpulmonary hypertension). The results show that the correlation between them is verysignificant. This method is simple, convenince,and more valuable especially in thosepatients whose PA or LA tube has not been placed or has been extracted after opera tion in ICU.
