高血压病患者P波离散度与阵发性心房颤动关系的临床研究

Clinical Study Relation of the Pdisp and Paroxysmal Atrial Fibrillation for Hypertension Patients

目的探讨P波离散度(Pdisp)预测高血压病患者并发阵发性心房颤动发生的价值。方法选择我院住院患者80例,分为A、B组,A组为有阵发性心房颤动的高血压病患者,B组为无阵发性心房颤动的高血压病患者;12导联用同步自动分析心电图,记录窦性心律时12导联同步心电图。P波起点与等电位线交点为P波测量终点,每个导联测量5个图形清晰的P波,取平均值为该导联P波持续时间,其中最大P波时限(Pmax)与最小P波时限(Pmin)之差即为P波容散度(Pdisp)。结果并发有阵发性心房颤动的高血压病患者组的Pmax、Pdisp均显著大于无阵发性心房颤动的高血压病患者组,P值均<0.01。结论体表心电图Pdisp可作为高血压病患者并发阵发性心房颤动发生的预测因子。

Objective To evaluate the vale of Pdisp calculate hypertension patients with paroxysmal atrial fibrillation. Methods Choose 80 inpatients divide team A and B, A was the hypertension patients with paroxysmal atrial fibrillation, B was without. Apply 121ends synchronization voluntarily analyse electrocardiogram, record 12 lends synchronization electrocardiogram in the time sinus rhythm. P - wave measure destination is intersection point of P - wave origin and equal distance potential - line, each lends measure five P - waves with vivid figure, the average value is the last - time of this lends P - wave, Pdisp is the differe, nce between Pmax and Pmin. Results The Pmax and Pdisp of the hypertension patients with paroxysmal atrial fibrillation were greater than the patients without, the P - values were smaller than 0.01. Verdicts The Pdisp of the 体表 electrocardiogram may as the calculate factor of the hypertension patients with paroxysmal atrial fibrillation.
