目的：探讨12导联动态心电图对早期复极综合征的诊断价值。方法回顾分析了我院半年间1896例动态心电图，对符合早期复极综合征诊断标准的患者进行严格筛选。结果共检出113例，检出率为5.96%，其中男性80例，女性33例，年龄15～69岁。动态心电图检出率明显高于普通心电图（100%：12%，P＜0.05），Ⅰ型明显多于Ⅱ型（87.6%：7.1%，P＜0.05），Ⅰ型也明显多于Ⅲ型（87.6%：5.3%，P＜0.05），Ⅱ型与Ⅲ型相比无显著性差异（7.1%：5.3%， P＞0.05）。结论12导联动态心电图在早期复极综合征中有重要的诊断价值，检出以Ⅰ型为主，Ⅱ型、Ⅲ型占少数，其中对极少部分不良早期复极有着不可忽视的预警作用。“,”Objective To explore the value of 12-lead dynamic electrocardiogram in the diagnosis of Early Repolarization Syndrome(ERS). Methods We retrospectively analyze 1896 patients who recorded dynamic electrocardiograms in our hospital and selected patients with ERS. Results ERS was found in 113 patients (5.96%), among them 80 were male, female 33, 15 to 69 years old. The detection rate of ERS by dynamic electrocardiogram is significantly higher than that of normal electrocar- diogram (100%:12%, P<0.05).Among them, typeⅠwas much more than type Ⅱ(87.6%:7.1%, P<0.05) and type Ⅰ was also much more than type Ⅲ (87.6%:5.3%, P0.05). Conclusion 12-lead dynamic electrocardiogram has important diagnostic value in ERS. Type Ⅰ is main among them. Type I and type II are less.Most importantly, dynamic electrocardiogram may play an important role in warning some malignant form of ERS.
