摘要 目的探讨阵发性房颤的左室质量指数(LVMI)和P波离散度(PD)以及与血瘀证积分的相关性。方法 90例非瓣膜病阵发性房颤(PAF)患者,随机分为血瘀证组与非血瘀证组,另选健康体检者30名为对照组,比较PAF血瘀证组、非血瘀证组以及血瘀证不同积分组的LVMI、左房内径(LADD)、P波最大时限(Pmax)、PD。结果血瘀证组、非血瘀证组LVMI、Pmax、PD、LADD与对照组相比均明显升高(P<0.05或P<0.01);血瘀证组LVMI、PD与非血瘀证组相比差异有统计学意义(P<0.05),而Pmax、LADD差异无统计学意义(P>0.05)。血瘀证积分≥10分组LVMI、PD与血瘀证积分<10分组比较,差异有统计学意义(P<0.05),而Pmax、LADD差异无统计学意义(P>0.05)。结论 PAF血瘀证患者LVMI、PD增加程度比非血瘀证患者更为明显;随着血瘀程度加重,LVMI、PD值也随之增加。因此,血瘀可能参与心脏组织重构,引起心房扩大、心肌纤维化,使心房的解剖结构变化和电活动异常,从而导致PAF发生发展。
