摘要
目的探讨特发性异常J波与Brugada综合征的临床及心电学特点。方法对特发性异常J波与Brugada综合征各8例进行分析。结果①特发性异常J波在肢导联或（和）胸导联可见正向异常J波[除aVR（部分患者aVL）外]，其波幅较低而分布较广，一般V1-V2导联不出现J波，若出现则Jv1-v2〈R，不伴右束支传导组滞（RBBB），TV1-V3常直立；②Brugada综合征及Brugada样心电图象在V1～V3导联ST段呈下斜或马鞍型抬高伴RBBB或类RBBB，R’〉R，TV1-V2（V3）倒置或直立。两者均易诱发多形性室性心动过速及／或心室颤动而致死。结论异常J波和Bmgada综合征及Bmgada样心电图象是具有不同临床及心电学特点的临床病症。
Objective To explore the clinical and electrocardiographic character of idiopathic abnormal J wave and Brugada＇ s syndrome. Methods Eight cases with idiopathic abnormal J wave and eight cases with Brugada＇s syndrome were analyzed. Results 1.There was upright abnomral J wave in limb/or precordial leads in idiopathic abnormal J wave cases, except in lead aVR or aVL. The J wave was obviously lower and distributed more extensively than that in Brugada＇s syndrome. Generally there was no J wave in lead V1 - V2, if J wave appeared, it was smaller than R wave. The T wave was usually upright and without right bundle branch block （RBBB） in leads V1 - V3. 2. In Brugada＇s syndrome, ST segment was elevation with slanting or saddle type accompanied with RBBB or RBBB- like, R＇ wave was higher than R wave in leads V1 - V3 and T wave was often inversion or upright in leads V1 - V3. In both instances, polymorphic ventricular tachycardia （PVT） and ventricular fibrillation （VF） were more often induced and led to death. Conclusions The idiopathic abnormal J wave is different from Brugada＇s syndrome in clinical and electrocardiographic character.
