小儿室上性心动过速心电图临床诊断分析

Clinical Diagnosis of Supraventricular Tachycardia Electrocardiogram in Children

目的分析体表心电图在小儿室上性心动过速(SVT)临床诊断以及分型中的应用价值。方法方便选择该院于2017年10月—2018年12月期间收治的室上性心动过速患儿79例,所有患儿均接受电生理检查,对检查资料进行回顾性分析。结果79例患儿经电生理检查确诊为室上性心动过速,确诊率为100.00%,而71例患儿经体表心电图检查后得到确诊,诊断有效率为89.87%,对比电生理检查与体表心电图检查结果,组间差异无统计学意义(χ^2=1.4267,P=0.8637);分析患儿的室上性心动过速构成情况,占比最高的是房室折返性心动过速(AVRT),占比为69.01%(49例),其次为房室结折返性心动过速(AVNRT),占比为26.76%(19例),其他占比为4.23%(3例)。结论室上性心动过速患儿临床诊断中采取体表心电图方案,不仅对患儿病情的确诊率较高,而且可以对患儿室上性心动过速的构成情况进行有效判定,有利于患儿的后期临床治疗,因此值得推广使用。

Objective To analyze the value of surface electrocardiogram in the clinical diagnosis and classification of supraventricular tachycardia (SVT). Methods A total of 79 children with supraventricular tachycardia admitted to our hospital from October 2017 to December 2018 were convenient enrolled. All patients underwent electrophysiological examination and retrospective analysis of the examination data. Results 79 patients were diagnosed as supraventricular tachycardia by electrophysiological examination. The diagnosis rate was 100.00%, and 71 children were diagnosed by electrocardiogram. The diagnostic effective rate was 89.87%. The results of surface electrocardiogram were statistically significant(χ^2=1.426 7,P =0.863 7). The composition of supraventricular tachycardia was analyzed. The highest proportion was atrioventricular reentry tachycardia (AVRT), accounting for 69.01%(49 cases), followed by atrioventricular nodal reentry tachycardia (AVNRT), accounting for 26.76%(19 cases). The other proportion was 4.23%(3 cases). Conclusion The surface electrocardiogram program is adopted in the clinical diagnosis of children with supraventricular tachycardia. It not only has a high diagnosis rate of the child's condition, but also can effectively determine the composition of supraventricular tachycardia in the child, which is beneficial to the patients' later clinical treatment, so it is worth promoting.
