Azithromycin is used to treat pediatric COVID-19 patients. It can also prolong the QT interval in adults. This study assessed the effects of azithromycin on ventricular repolarization in children with COVID-19.
The study prospectively enrolled children with COVID-19 who received azithromycin between July and August 2020. An electrocardiogram was performed before, one, three, and five days post-treatment. Using ImageJ®, the following parameters were measured: QT max, QT min, Tp-e max, and Tp-e min. The parameters QTc max, QTc min, Tp-ec max, Tp-ec min, QTcd, Tp-ecd, and the QTc/Tp-ec ratio were calculated using Bazett's formula.
The study included 105 pediatric patients (mean age 9.8±5.3 years). The pretreatment heart rate was higher than after treatment (before 92 [79-108]/min vs. Day 1 82 [69-108)]/min vs. Day 3 80 [68-92.2]/min vs. Day 5 81 [70-92]/min; p=0.05).
Azithromycin does not affect the ventricular repolarization parameters on ECG in pediatric COVID-19 cases.
阿奇霉素用于治疗儿童新冠病毒肺炎患者。它在成人中还可延长QT间期。本研究评估了阿奇霉素对新冠病毒肺炎患儿心室复极的影响。
本研究前瞻性纳入了2020年7月至8月期间接受阿奇霉素治疗的新冠病毒肺炎患儿。在治疗前、治疗后1天、3天和5天进行心电图检查。使用ImageJ®测量以下参数：QT最大值、QT最小值、Tp-e最大值和Tp-e最小值。使用Bazett公式计算QTc最大值、QTc最小值、Tp-ec最大值、Tp-ec最小值、QTcd、Tp-ecd以及QTc/Tp-ec比值。
该研究纳入了105例儿科患者（平均年龄9.8±5.3岁）。治疗前心率高于治疗后（治疗前92[79 - 108]/分钟 vs. 第1天82[69 - 108]/分钟 vs.第3天80[68 - 92.2]/分钟 vs.第5天81[70 - 92]/分钟；p = 0.05）。
在儿童新冠病毒肺炎病例中，阿奇霉素不影响心电图上的心室复极参数。
