Abstract

: Exercise-induced modifications in ECG parameters among individuals with an early repolarization pattern (ERP) have not been evaluated in detail. We aimed to assess this phenomenon, with potential associations with arrhythmogenesis. : Twenty-three young, healthy males with ERP (ERP+) participated in this study, alongside a control group, which consisted of nineteen healthy males without ERP (ERP-). ECGs at baseline, at peak exercise (Bruce protocol), and during the recovery phase were analyzed and compared between the two groups. : The treadmill test demonstrated strong cardiovascular fitness, with similar chronotropic and pressor responses in both groups. In the baseline ECGs, the QRS complex and the QT interval were shorter in the ERP+ group. During exercise, the P-wave duration was significantly longer and the QRS was narrower in the ERP+ group. In the recovery phase, there was a longer P wave and a narrower QRS in the ERP+ group. During the treadmill test, the J wave disappeared or did not meet the criteria required for ERP diagnosis. : The slowed intra-atrial conduction found during exercise could be predictive of atrial arrhythmogenesis in the setting of ERP. The disappearing of J waves during exercise, due to increased sympathetic activity, has potential clinical significance.

摘要

早期复极模式（ERP）个体运动诱导的心电图参数改变尚未得到详细评估。我们旨在评估这一现象及其与心律失常发生的潜在关联。23名具有ERP的年轻健康男性（ERP+）参与了本研究，同时设立了一个对照组，该对照组由19名无ERP的健康男性（ERP-）组成。分析并比较了两组在基线、运动高峰（Bruce方案）和恢复阶段的心电图。跑步机测试显示两组心血管适应性良好，变时性和升压反应相似。在基线心电图中，ERP+组的QRS波群和QT间期较短。运动期间，ERP+组的P波时限显著延长，QRS波变窄。在恢复阶段，ERP+组的P波更长，QRS波更窄。在跑步机测试期间，J波消失或不符合ERP诊断所需标准。运动期间发现的心房内传导减慢可能预示着ERP情况下的房性心律失常发生。运动期间由于交感神经活动增加导致J波消失具有潜在临床意义。
