目的 观察老年高血压非左室肥厚患者房颤与左心结构和功能改变的关系。方法 75例老年高血压非左室肥厚患者,其中伴房颤者39例,不伴房颤者36例,比较2组临床及多普勒超声心动图特点。结果 房颤组左房内径较对照组明显增加,射血分数明显降低(P<0.05),心功能较对照组差,且室性心律失常的发生率明显高于对照组。结论 老年高血压非左室肥厚患者的房颤发生率与左房内径成正相关,且发生房颤后心功能明显下降,恶性心律失常的发生率明显增加。
Objective To observe the relationship between atrial fibrillation and left ventricular structure and function in elderly hypertensive patients with non-left ventricular hypertrophy. Methods Seventy-five elderly patients with hypertensive non-hypertrophic hypertrophy, including 39 with atrial fibrillation and 36 without atrial fibrillation, were included in this study. Clinical and Doppler echocardiographic characteristics were compared between the two groups. Results Compared with the control group, the left atrial diameter of AF group was significantly increased, the ejection fraction was significantly lower (P <0.05), the cardiac function was worse than that of the control group, and the incidence of ventricular arrhythmia was significantly higher than that of the control group. Conclusion The incidence of atrial fibrillation in elderly hypertensive patients with non-left ventricular hypertrophy is positively correlated with left atrial diameter. The incidence of atrial fibrillation is significantly decreased and the incidence of malignant arrhythmia is significantly increased after atrial fibrillation.
