高血压左室肥厚心率变异的临床观察

目的：探讨高血压左心室肥厚与心率变异的关系。方法：选取在我院治疗的高血压患者130例作为观察组，同期98例健康对照者为对照组，检查超声心动图和24小时动态心电图，并将观察组按有无左室肥厚分为亚组，分析心率变异情况。结果：观察组心率变异明显小于对照组，观察组中伴有左室肥厚的患者心率变异明显小于不伴有左室肥厚的患者（p〈0．05）。结论：高血压可使心率变异性明显减低，尤其是合并有左室肥厚，心率变异性改变更明显。

Hypertensive left ventricular hypertrophy and heart rate variability in clinical observation

Objective： To investigate hypertensive left ventricular hypertrophy and heart rate variability relationship. Methods： in my hospital for treatment of 130 cases of hypertension as the observation group, 98 cases of healthy subjects as control group, ultrasonography heartbeat graph and dynamic electrocardiogram for 24 hours, and the observation group according to the with and without left ventricular hypertrophy is divided into subgroups, analysis of heart rate variability. Results： heart rate variability of the observation group is significantly smaller than the control group, the observation group with left ventricular hypertrophy of heart rate variability in patients was significantly smaller than that without left ventricular hypertrophy patients （ P 〈 0. 05 ） . Conclusion： hypertension to heart rate variability decreased markedly, especially with left ventricular hypertrophy, heart rate variability is more obvious.
