老老年高血压病患者左心室肥厚与心律失常及心率变异性的关系研究

目的：研究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例老老年高血压病患者,根据是否合并左心室肥厚分为2组,检测24小时动态心电图心率变异性时域分析及超声心动图,观察2组之间相关指标的差异。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),二组PNN50、RMSSD、SDNN、SDANN差异无统计学意义。结论：老老年高血压合并LVH心律失常的发生率明显增高,而二者心率变异性无明显差异。

The relationship between old elderly hypertensive patients with left ventricular hypertrophy and cardiac arrhythmias and heart rate variability

Objective: Explore the relationship between the very elderly hypertensive patients with left ventricular hypertrophy (LVH) and heart rate variability (HRV). Methods: The study included 303 very elderly patients with hypertension. According with left ventricular hypertrophy, hypertension are divided into two groups .Test 24-hour ambulatory ECG, heart rate variability and echocardiography. Analysis differences between arrhythmia and heart rate variability in the two groups. Results: In the aspects of atrial arrhythmias and ventricular arrhythmias, the group of hypertensive with LVH is more than the group without LVH (P <0.05), but no statistically significant changes in HRV. Conclusion: The incidence of very elderly hypertensive patients with LVH arrhythmia was significantly higher, while both no significant difference in heart rate variability.
