心脏性晕厥或猝死的若干高危心电表现

Some high risk electrocardiogram expression of sudden cardiac death or cardiac syncope

目的探讨快速性心律失常所致心脏性晕厥或猝死的高危心电图表现。方法分析入院时或入院后至少发生1次心脏性晕厥或猝死的33例患者发作时与发作前后的常规12导联心电图或持续心电监护心电图。结果引起心脏性晕厥或猝死的若干高危心电图表现:①长Q-T间期综合征,②Brugada综合征,③异常J波,④复杂性室性期前收缩,⑤冠心病急性心肌梗死呈广泛前壁心肌梗死伴新出现的右束支传导阻滞及弓背抬高的ST段持续不降,或伴ST-T电交替;或广泛前壁心肌梗死伴墓碑样ST段抬高,⑥扩张型心肌病伴进展性QRS波群低电压。结论心脏性晕厥或猝死存在多种高危心电图表现。
