摘要

目的探讨儿童多系统炎症综合征（MIS-C）的P波、QT间期和校正QT间期离散度与临床病理的关系。方法本研究纳入60名根据美国疾病控制与预防中心诊断为misc的儿童和26名健康儿童。用12导联体表心电图测定患者的最大、最小P波持续时间和QT间期持续时间。结果miss - c患儿的p波和QT间期离散度明显大于健康儿童(p <；0.001)。此外，misc患儿治疗前P波和QT间期离散度明显大于治疗后(P <；0.001)。结论我们的研究发现，患者组P波离散度和QT离散度明显高于对照组。这与misc中出现心律失常的频率有关。我们建议患有misc的住院患者应仔细监测潜在的心律失常。

Evaluation of P wave and QT interval dispersion in multisystem inflammatory syndrome in children

Purpose

To examine the associations between P wave, QT interval, and corrected QT interval dispersion and clinical pathologies in multisystem inflammatory syndrome in children (MIS-C).

Methods

This study included 60 children diagnosed with MIS-C according to the US Centers for Disease Control and Prevention criteria and 26 healthy children. Their maximum and minimum P wave durations and QT interval durations were measured by 12‑lead surface electrocardiography.

Results

P wave and QT interval dispersion were significantly greater in the children with MIS-C than in the healthy children (p < 0.001). In addition, P wave and QT interval dispersion were significantly greater before than after treatment among the children with MIS-C (p < 0.001).

Conclusions

Our study found significantly greater P wave dispersion and QT dispersion in the patient group than in the control group. This correlates with the frequency of arrhythmias seen in MIS-C. We suggest that patients hospitalized with MIS-C should be meticulously monitored for potential arrhythmias.
