摘　　要：目的探讨P波离散度对脑卒中患者发生阵发性房颤及预后的预测价值。方法选择72例脑卒中患者,根据有无阵发性房颤分为A组(伴有阵发性房颤)36例和B组(不伴有阵发性房颤)36例,两组患者均行12导联心电图及彩色多普勒超声心动图,24 h动态心电图检测,分别测量心电图P波最大时限(P max)、P波最小时限(P min),计算P波离散度(Pd)、左心房内径(LAD)、左心室射血分数(LVEF),并进行比较。结果两组间P波最大时限(P max)、P波离散度(Pd)、左心房内径(LAD)、左心室射血分数(LVEF)、频发房早、短阵房速比较,差异有统计学意义(P<0.05)。结论 P波离散度是预测脑卒中患者并发阵发性房颤的可靠指标,对预后观测有一定意义。Objective To investigate the predictive value of P-wave dispersion on the prognosis and paroxysmal atrial fibrillation （PAF） of cerebral apoplexy patients. Methods Seventy-two patients with cerebral apoplexy were enrolled in the research, among whom 36 cases with PAF and another 36 cases without PAF were separately regarded as group A and group B. Both of the two groups underwent 12 lead electrocardiogram（ECG）, colored Doppler echocardiography and 24-hour Holter inspection, with the maximum P-wave duration （Pmax）, the minimum P-wave duration（Pmin） measured and P-wave dispersion（Pal）, left atrial diameter（LAD） and left ventricular ejection fraction（LVEF） calculated. The results were statistically analyzed by PEMS 3.1 for Windows. Results Between the two groups, it revealed significant statistical differences in Pmax, Pd, LAD, LYEF and the number of cases of atrial premature beats as well as paroxysmal atrial tachycardia（P 〈 0.05）. Conclusion P-wave dispersion serves as a reliable marker for predicting the complication of paroxysmal atrial fibrillation for patients with cerebral apoplexy and is also significant for prognosis observation in some extent.
