摘要 目的:探讨前瞻性观察单腔起搏器睡眠功能开放对左心功能的影响及可能机制。方法:31例Ⅲ度房室传导阻滞患者成功置入永久单腔心脏起搏器,随机分为睡眠功能开放组及未开放,分别在植入后出院前、1年、2年时随访时,测定右室起搏比率,24h总心搏数及心房颤动发生率,左室舒张末内径(LVEDD),射血分数(EF)。结果:两组的右室起搏比率比较,差异无统计学意义;两组在刚植入时24h总心搏数的比较,差异无统计学意义;1年及2年时总心搏数比较,差异有统计学意义;心房颤动发生率在刚植入时差异无统计学意义,1年及2年时差异有统计学意义;LVEDD及EF变化:开放组差异无统计学意义;对照组差异有统计学意义。结论:睡眠功能开放可减少右室起搏数量,延缓左室扩大,减少心功能下降。 Objective:To Explore prospective observational single-chamber pacemaker sleep function to open on left ventricular function and its possible mechanism.Methods:31 cases Ⅲ degree atrioventricular block were successfully implanted a permanent singlechamber pacemakers were randomly divided into the sleep function of the open group and is not open,respectively,after implantation,before discharge,1 year,2 years of follow-up determination the ratio of right ventricular pacing,24 hours the number of total stroke and atrial fibrillation rate,left ventricular end diastolic diameter(LVEDD),ejection fraction(EF).Results:Two groups of right ventricular pacing rate,the difference was not statistically significant;the two groups at the implantation 24h total stroke number,the difference was not statistically significant;1 year and 2 years,the total stroke number,the differencestatistically significant;no significant difference in the incidence of atrial fibrillation implanted in just 1 year and 2-year difference was statistically significant;LVEDD were and EF changes: open group was not statistically significant;control group showed a statisticallysignificance.Conclusion:The sleep function open can reduce the number of right ventricular pacing,the delay left ventricular enlargement and to reduce the decline in cardiac function.
