Abstract
Objective: To determine the prevalence, characteristics, and sex differences of early repolarization pattern (ERP) in pediatric athletes.
Design: Prospective observational study.
Setting: Large popular race in Geneva, 2018 to 2024.
Participantsintotal,: 428 athletes aged 8 to 17 years, training ≥6 hours per week.
Interventions: Participants underwent history, physical examination, and 12-lead electrocardiography (ECG) interpreted according to athlete-specific recommendations. ERP was defined using Macfarlane criteria.
Main outcome measures: Prevalence and morphology of ERP, ECG parameters, and sex-related differences.
Results: ERP was present in 62 athletes (14.5%), with similar prevalence in boys (16.4%) and girls (13.1%; P = 0.676). Notched ERP (40.0% vs 12.0%; P = 0.022) and ascending ST slopes (80.0% vs 52.2%; P = 0.041) were more frequent in boys, whereas slurred ERP and flat/descending slopes predominated in girls. Compared with athletes without ERP, those with ERP showed shorter QRS duration (85.4 ± 6.9 vs 89.9 ± 11.0 ms; P = 0.002), shorter QTc interval (415.1 ± 19.2 vs 423.5 ± 19.5 ms; P = 0.002), and more leftward P-wave axis. Normal ECG findings were more frequent in ERP athletes (98.3% vs 72.1%; P < 0.001).
Conclusions: ERP occurred in 1 in 7 pediatric athletes and clustered with benign ECG adaptations. Boys more often exhibited notched ERP, girls slurred ERP, indicating sex-related morphological differences despite similar prevalence.
目的：了解小儿运动员早期复极模式（ERP）的患病率、特点及性别差异。设计：前瞻性观察研究。背景：2018年至2024年在日内瓦举行的大型热门赛事。参与者：428名运动员，年龄8 - 17岁，每周训练≥6小时。干预措施：参与者接受病史、体格检查和根据运动员特定建议解释的12导联心电图（ECG）。ERP采用麦克法兰标准定义。主要结果测量：ERP的患病率和形态、心电图参数和性别相关差异。结果：运动员中有62例（14.5%）存在ERP，男孩（16.4%）和女孩（13.1%）患病率相似，P = 0.676。缺口型ERP （40.0% vs 12.0%, P = 0.022）和上升型ST斜率（80.0% vs 52.2%, P = 0.041）在男孩中更为常见，而在女孩中则以模糊型ERP和平缓/下降型斜坡为主。与无ERP的运动员相比，ERP组QRS持续时间短（85.4±6.9 ms vs 89.9±11.0 ms, P = 0.002）， QTc间隔短（415.1±19.2 ms vs 423.5±19.5 ms, P = 0.002）， P波轴偏左。正常心电图在ERP运动员中更为常见（98.3% vs 72.1%; P < 0.001）。结论：ERP发生在1 / 7的儿童运动员中，并与良性心电图适应聚集在一起。男孩更常表现为缺口型ERP，女孩更常表现为模糊型ERP，尽管患病率相似，但表明与性别相关的形态学差异。
