摘要 目的 探讨高血压病患者P波离散度改变规律。方法 观察 3 4例高血压并阵发性心房颤动患者 (房颤组 )的最宽P波 (Pmax)和P波离散度 (Pdisp) ,并与 3 9例无阵发性心房颤动的高血压病患者 (对照组 )对比分析。结果 房颤组的Pdisp为 5 1± 11ms ,其中Pdisp≥ 40ms为 2 9例 (85 .2 9% ) ;对照组的Pdisp为 3 6± 9ms ,其中Pdisp≥ 40ms为 5例 (12 .82 % )。两组比较差异均有高度显著性 (P <0 .0 1)。结论 Pdisp是预测高血压病患者心房颤动发生的可靠指标 ,当Pdisp≥ 40ms时预测有较高的敏感性和特异性。
