摘要
目的:探讨P波离散度与老年高血压病并发阵发性房颤关系。方法:检测68例老年高血压病并发阵发性房颤患者(观察组)的最大P波时限(Pmax)、P波离散度(Pd),并与42例老年高血压病无阵发性房颤患者(对照组)进行比较,同时应用多普勒超声心动图测量的两组各20例患者的左房内径(LAD)及左室射血分数(LVEF)的变化。结果:Pmax、Pd:观察组均显著大于对照组(P<0.01)。LAD两组无显著差异(P>0.05);LVEF观察组较对照组显著降低(P<0.05)。结论:Pmax和Pd可作为预测老年高血压病并发阵发性房颤最简单的心电图指标。
Objective: To understand relationship between geriatric hypertension with paroxysmal atrial fibrilation (PAF) and P wave dispersion. Methods: The maximum P wave duration (Pmax) and wave dispersion (Pd) from the 12 -lead surface electro-cardiogram of 68 essential hypertensive patients with history of PAF (group I . mean age 76) and 42 essential hypertensive patients without history of AF (group Ⅱ, mean age 78) were measured. Results: Pmax and Pd were found to be significantly higher in group I than those of group Ⅱ (P<0. 01 all) . LVEF were significantly lower in group I than that of group I (F<0. 05) ;but LAD was no significantly (P>0. 05). Conclusion: Pmax and Pd are simple electrocardiographic markers that can be used for prediction of hypertensive patients at risk of developing PAF.
