摘要 目的:探讨美托洛尔缓释片对高血压伴阵发性房颤患者P波离散度(Pd)的影响。方法:高血压伴阵发性房颤患者58例随机分为美托洛尔缓释片治疗组(A组)和对照组(B组),每组29例。两组高血压降压治疗基本相同,均使用钙阻抗剂或ACEI、ARB类药。A组加用美托洛尔缓释片25~50mg/日。在治疗前、治疗后6个月分别测量P波最大时限Pmax和P波最小时间(Pmin),计算出Pd(Pd=Pmax-Pmin)。结果:治疗前两组Pmax和Pd比较无显著性差异(P>0.05);治疗6个月后两组Pmax和Pd不同程度下降,治疗组比对照组的Pmax和Pd下降得更多,有非常显著性差异(P<0.01)。结论:美托洛尔缓释片治疗高血压伴阵发性房颤患者可明显降低Pd,提示可减少心房纤颤的发生。
