| 摘 要： | 目的 探讨原发性高血压合并左心室肥厚(LVH)患者的心率振荡(HRT)现象.方法 人选276例原发性高血压患者,均进行心脏彩超检查及Holter记录,计算左心室重量、左心室重量指数(LVMI)、震荡初始(TO)及震荡斜率(TS);以LVMI男性>125g/m2、女性>120g/m2和(或)室间隔厚度(IVST)>12mm作为LVH标准,分LVH组及左室正常组.结果 TO及TS在LVH组分别为(1.19±0.84)%及(4.23±0.85)ms/RR,左室正常组分别为(-0.54±0.86)%及(6.81±1.22)ms/RR,两组TO、TS值及异常比率均有显著性差异(P<0.01);TO与左室射血分数(LVEF)、左室舒张末期内径(LVEDD)及LVMI显著相关(P<0.05).TS与LVEF、IVST显著相关(P<0.05),与LVEDD及LVMI相关性更显著(P<0.01).结论 原发性高血压伴LVH患者的HRT现象明显减弱,提示高血压合并LVH时,自主神经功能受损加重.

| Abstract: | Objective To investigate the characteristics of heart rate turbulence (HRT) in essential hypertension(EH) with left ventricular hypertrophy (LVH). Methods A total of 276 (EH) patients were enrolled in this study. All consent information was obtained. All patients received echocardiographic measurement of left ventricular mass index (LVMI), and then were divided into group LVH (with interventricular septal thickness greater than 12 mm) and group N (with normal left ventricular thickness).All patients of both... |
