中文摘要:
      目的:评价窦性心动过缓人群的心脏变时性功能;比较运动试验与动态心电图对心脏变时性功能检测的价值?方法:选择窦性心动过缓患者(窦缓组)67例和窦性心律?心率正常者(对照组)47例,进行运动平板试验和动态心电图检测,观察运动试验中的最大心率和动态心电图的最大心率?心脏变时性功能不全的诊断标准:运动试验以运动后最大心率未达85%年龄预测心率,动态心电图以最大心率不超过100次/min?结果:①采用运动试验诊断标准:窦缓组心脏变时性功能不全16例(23.88%),对照组4例(8.51%),两组间有显著性差异(P < 0.05);②窦缓组中运动试验对心脏变时性功能不全的诊断率为23.88%,显著高于动态心电图的7.46%(P < 0.05)?结论:窦性心动过缓人群心脏变时性功能不全的发生率明显高于正常心率者,运动试验对心脏变时性功能不全的诊断价值优于动态心电图?
英文摘要:
      Objective:To investigate the incidence of chronotropic incompetence(CI) in a cohort of sinus bradycardia and the value of CI between exercise test(ET) and Holter monitoring electrocardiogram(Holter). Methods:Sixty-seven subjects of sinus bradycardia(48 male and 19 female,the mean age of 46.7 ± 13.9 years) and 47 control subjects of normal heart rate(34 male and 13 female, the mean age of 48.4 ± 7.6 years) received treadmill exercise test and Holter detection. The maximal heart rate during ET and Holter were observed. CI was defined as the failure to achieve 85% of the age predicted maximal heart rate(APMHR) during ET or failure to 100bpm during Holter. Results:①Sixteen sinus bradycardia subjects(23.88%) and 4 normal control subjects(8.51%) than 85% of APMHR(P < 0.05). ②The prevalence of CI achieved less diagnosed by ET was 23.88% and 7.46% diagnosed by Holter in the subjects of sinus bradycardia(P < 0.05). Conclusion:The population with sinus bradycardia has a higher incidence of chronotropic incompetence. ET is a more valuable diagnostic technique to CI than Holter.
