摘　　要：目的探讨老年高血压患者静息心率(RHR)与动态血压参数和左心室肥厚的关系。方法入选老年高血压患者103例,按RHR水平分为RHR 1组32例:RHR<70/min,RHR 2组38例:70/min≤RHR<80/min,RHR 3组33例:RHR≥80/min。入选患者均行静息心电图、动态血压等检查,并进行比较。结果 RHR 3组的24h、昼间、夜间平均收缩压及脉压明显高于RHR 2和RHR 1组,差异有统计学意义(P<0.05,P<0.01)。RHR与24h收缩压、24h脉压呈正相关(r=0.509,r=0.407,P<0.01),与LVEF呈负相关(r=-0.522,P<0.01)。结论老年高血压患者RHR增快与收缩压、脉压及左心室肥厚密切相关。在控制血压的同时,应注重加强对心率的控制。Objective To study the relation of resting heart rate （RHR） with ambulatory blood pressure and left ventricular hypertrophy （LVH） in elderly hypertensive patients. Methods One hundred and three elderly hypertensive patients were divided into RHR〈70/min group （n=32）, 70/min≤RHR〈80/min group （n=38） and RHR≥80/min group （n=33）. The patients underwent resting electrocardiography and carotid ultrasonography. Results The average 24 h,daytime and nighttime SBP and PP were significantly higher in RHR≥80/min group than in RHR〈70/ rain group and 70/min≤RHR〈80/min group （P〈0.01 ,P〈0.05）. The RHR was positively related with 24 h SBP and PP （r=0. 509,r=0. 407,P〈0.01） and negatively related with LVEF （r=-0. 522,P〈0.01）. Conclusion Since RHR is closely related with SBP,PP and LVH in elderly hypertensive patients,their RHR should controlled with blood pressure.
