简介:1病例报告患者男性,79岁.主因发作性心前区闷痛2竽,活动后气短5年余,拟诊为冠心病,陈旧性前间壁心肌梗死,频发室性早搏,间歇性完全性右束支传导阻滞,心功能4级入院.患者1995年10月8日心电图出现间歇性完全性右束支传导阻滞(图1),之前为正常心电图(图2).1995年10月9日始表现为持续性完全性右束支传导阻滞,其后共行心电图检查12次,均表现为完全性右束支传导阻滞(图3),并于1996年10月9日行动态心电图检查,亦表现为持续性完全性右束支传导阻滞.
简介:目的中国汉族人群中SCN5A基因A1673G多态与孤立阵发房颤的相关性。方法选取汉族孤立阵发房颤患者120例为观察组,以健康汉族人群120例为对照组,采用限制性片段长度多态性分析(RFLP),对SCN5A基因A1673G的多态位点进行基因型鉴定,并随机挑选样本进行测序,检验其可靠性。结果SCN5A基因A1673G多态位点在中国汉族人群孤立阵发房颤患者和正常组比较,基因型频率符合Hardy-Weinberg平衡定律;A1673G多态的基因型频率在两组间差异有统计学意义(P〈0.05),房颤患者G等位基因高于正常组;GG基因型对房颤患者有明显影响(P〈0.05)。结论SCN5A基因变异可能与中国汉族人群孤立阵发性房颤相关。
