背景：已知用信号平均心电图检测到的晚电位 (LP) 可用于识别有 Brugada 综合征 (BS) 和致心律失常性右心室心肌病 (ARVC) 风险的患者。由于这些疾病之间的病理生理学明显不同，我们阐明了这些疾病的 LP 特征。方法和结果-本研究包括 15 名 BS 和 12 名 ARVC 患者以及 20 名健康对照。所有 BS 患者都有特征性心电图变化和症状发作。所有 ARVC 患者的检查结果均符合最新标准。三个 LP 参数（滤波后的 QRS 持续时间、滤波后的 QRS 复合波终端 40 ms 的均方根电压以及低幅度信号的持续时间 [
Background-Late potentials (LP) detected with signal-averaged ECGs are known to be useful in identifying patients at risk of Brugada syndrome (BS) and arrhythmogenic right ventricular cardiomyopathy (ARVC). Because the pathophysiology is clearly different between these disorders, we clarified the LP characteristics of these disorders.Methods and Results-This study included 15 BS and 12 ARVC patients and 20 healthy controls. All BS patients had characteristic ECG changes and symptomatic episodes. All ARVC patients had findings that were consistent with recent criteria. Three LP parameters (filtered QRS duration, root mean square voltage of the terminal 40 ms of the filtered QRS complex, and duration of low-amplitude signals [
