摘要
目的探讨P波离散度对老年高血压病并发心房颤动的影响。方法观察52例老年高血压病并发阵发性心房颤动患者(观察组)的最大P波时限(Pmax)、P波离散度(Pd),并与52例老年高血压病无阵发性心房颤动患者(对照组)比较。结果观察组和对照组的Pmax分别为(124.23±10.22)ms和(106.34±8.35)ms,Pd分别为(48.87±7.68)ms和(35.56±5.12)ms,前者均大于后者(P<0.01)。在观察组,Pmax≥110ms时,预测敏感性为75%,特异性为77.6%;Pd≥40ms时,预测敏感性为96%,特异性为91%。结论Pd可能是预测老年高血压病并发阵发性心房颤动发生的敏感心电图指标之一。
Objective To explore the effect of P wave dispersion on senile hypertension with paroxysmal atrial fibrillation （PAF）. Methods The maximum P wave duration（Pmax） and P wave dispersion（Pd） from 12-lead surface electrocardiogram of 52 old hypertension patients with history of PAF（ group 1 ） and 48 old hypertension patients without history of PAF（ group 2） were measured. Results Pmax and Pd were significant higher in group 1 than that in group 2 [ Pmax, （ 124.23 ± 10.22 ） ms vs （ 106.34 ±8.35） ms,P 〈0.01 ;Pd, （48, 87 ±7.68） ms vs（35.56 ±5, 12） ms,P 〈0, 01 ]. In the group 2,Pmax ≥110 ms and Pd ≥40 ms were with a higher sensitivity （75 % and 96% ） and specificity （77.6% and 91% ）. Conclusions Pd are electrocar- diography markers that can be used for the prediction of old hypertensive patients at risk of developing PAF.
