摘　　要：目的 探讨老老年高血压患者左心室肥厚（LVH）与心律失常及心率变异性（HRV）的关系.方法 纳入2012年10月至2014年7月于中国中医科学院广安门医院心内科住院的303例老老年高血压患者,根据是否合并左心室肥厚分为2组,检测24 h动态心电图心率变异性时域分析及超声心动图,观察两组间相关指标的差异.结果 老老年高血压合并LVH组较不合并LVH组房性、室性心律失常检出率增高,差异具有统计学意义（P＜0.05）,两组PNN50、RMSSD、SDNN、SDANN的P值分别为0.573、0.198、0.110、0.812,未见统计学差异.结论 老老年高血压合并LVH患者心律失常的发生率明显增高,而老老年高血压合并LVH和不合并LVH患者心率变异性无明显差异.Objective Explore the relationship between left ventricular hypertrophy（LVH） and heart rate variability（ HRV ） in the very elderly hypertensive patients. Methods The study included 303 very elderly patients with hypertension. According with left ventrieular hypertrophy, hypertension were divided into two groups. 24-hour ambulatory ECG, heart rate variability and eehoeardiography were compared between two groups. Results In the aspects of atrial arrhythmias and ventrieular arrhythmias, the group of hypertensive with LVH was more than the group without LVH （P〈0.05）, but no statistically significant changes in HRV （P〉0.05）. Conclusion The incidence of arrhythmia in very elderly hypertensive patients with LVH was significantly higher, while has no significant difference in heart rate variability.
