中文摘要：

目的：研究窦性心率震荡诊断2 型糖尿病合并隐性高血压患者的临床效果。方法：对2009 年12 月至2013年4 月我院心内科收治的2 型糖尿病合并高血压患者123 例进行回顾性分析，根据诊室内手测血压及24 h动态血压监测结果将患者分为高血压组（EH组）及隐性高血压组（MH）组，另取在我院体检的诊室及24 小时动态血压均正常者为NT组，三组研究对象均进行诊室内手测血压，24 h动态血压监测及HRT 检测，比较三组检测结果。结果：（1）诊室内手测血压结果显示MH 组收缩压及舒张压与NT组差异无统计学意义（P＞0.05）；EH 组收缩压及舒张压与NT组比较差异具有统计学意义（P＜0.05）。（2）24 h动态血压监测结果显示MH 组及EH 组收缩压与舒张压与NT 组比较差异均具有统计学意义（P＜0.05）。（3）HRT检测结果显示MH 组及EH组TO值与TS值与NT 组比较差异均具有统计学意义（P＜0.05）。结论：HRT 检测结果可作为诊断2 型糖尿病患者隐性高血压的一项可靠指标。

英文摘要：

Objective： To research the clinical effect of heart rate turbulence diagnosis for the patients with type 2 diabetes and hypertension. Methods： 123 patients with type 2 diabetic and hypertension in our hospital from May 2009 to August 2012 were analyzed retrospectively. All patients were divided into hypertension group （EH group） and masked hypertension group （MH group） by the blood pressure value measured in clinic and 24 h ambulatory monitoring. And the NT group was the people with normal blood pressure who were received physical examination in our hospital. The three groups were received blood pressure measure in clinical, 24h ambulatory monitoring and HRT detection. Results were compared. Results： （1） The results of blood pressure measure in clinic showed that the sys -tolic blood pressure and the diastolic blood pressure of MH group had no significant difference with NT group＇s（P〉0.05） and the systolic blood pressure and the diastolic blood pressure of EH group had significant difference with NT group＇s （P〉0.05）. （2）The results of 24h ambulatory monitoring showed that the systolic blood pressure and the diastolic blood pressure of EH group and MH group had significant difference with NT group＇s（P〉0.05）. （3） The results of HRT detection showed that TO and TS value of EH group and MH group had significant difference with NT group＇s（P〉0.05）. Conclusion： The results of HRT detection can be a reliable indicator in masked hyperten- sion diagnosis of patients with type 2 diabetic.
