目的:探讨P波离散度在高血压左室肥厚患者患心房颤动的预测价值。方法:选取38例高血压伴有心房颤动的患者,作为观察组,36例高血压不伴有心房颤动者作为对照组,比较两组之间心电图和超声检查指标的差异。结果:观察组在Pd、Pmax、LVMI较对照组明显增加,差异有显著统计学意义(P<0.01);两组间Pmin和LVEF差异无统计学意义(P>0.05)。相关分析显示,Pd是高血压左室肥厚患者心房颤动的独立预测因子。结论:P波离散度可用于高血压左室肥厚患者心房颤动的预测。
Objective: To investigate the predictive value of P wave dispersion in patients with hypertension and left ventricular hypertrophy. Methods: Thirty-eight hypertensive patients with atrial fibrillation were selected as the observation group and 36 hypertensive patients without atrial fibrillation as the control group. The differences between the two groups in ECG and ultrasound were compared. Results: The Pd, Pmax and LVMI in the observation group were significantly higher than those in the control group (P <0.01). There was no significant difference in the Pmin and LVEF between the two groups (P> 0.05). Correlation analysis showed that Pd was an independent predictor of atrial fibrillation in patients with hypertensive left ventricular hypertrophy. Conclusion: P wave dispersion can be used to predict atrial fibrillation in hypertensive patients with left ventricular hypertrophy.
