摘要
目的探讨正常血压高限值者窦性心率震荡(heartrate turbulence,HRT)的特征及其临床意义。方法选择45例正常血压高限值者(正常血压高限值组)及39例健康志愿者(对照组),进行24h动态心电图检查,离线分别计算震荡初始(TO)及震荡斜率(TS)。结果正常血压高限值者TO较对照组明显升高(p<0.05),TS明显降低(p<0.05)。结论正常血压高限值者存在室早后窦性心律震荡减弱,提示患者的自主神经功能明显受损。
Objective To explore the characteristics of heart rate turbulence （HRT） in patients with upperlimit normal blood pressure people and its clinical significance. Methods The HRT was measured in 45 patients with upperlimit normal blood pressure people and 39 healthy controls. Turbulence onset （TO）,turbulence slope（TS） were measured by the original definitions using digitized 24 hours Holter recordings. Results The value of the TO was significantly higher in patients with upperlimit normal blood pressure than healthy controls （p〈0.05）,while the value of the TS was significantly lower in patients with upperlimit normal blood pressure than in healthy controls （p〈0.05）. Conclusion HRT was significantly weaker in patients with upperlimit normal blood pressure people.
