早复极综合征是临床常见的一种心电图表现,以明显的J波和ST段凹面向上抬高为特征,常见于无器质性心脏病人群,无恶性或极少数恶性事件发生。半个世纪以来,被认为是特发性、良性综合征。近年来,随着J波细胞电生理学的研究发现,早复极综合征电生理机制和离子基础与心肌缺血、Brugad综合征、特发性室颤有相似之处,推断出少数患者在某种特定条件下也可能会发生恶性心律失常事件。所以在临床工作中对某些早期复极综合征要高度重视。
Early repolarization syndrome is a clinical manifestation of a common electrocardiogram, with obvious J wave and ST segment elevation upward for the feature, common in patients without organic heart disease, no malignant or a very small number of malignant events. For half a century, is considered idiopathic, benign syndrome. In recent years, with the J wave cell electrophysiological study found that the electrophysiological mechanism of early repolarization syndrome and ionic basis and myocardial ischemia, Brugad syndrome, idiopathic ventricular fibrillation have similarities, infer a small number of patients in a Malignant arrhythmias may also occur under certain conditions. So in clinical work for some early repolarization syndrome should attach great importance.
