摘要
目的:探讨高血压左室肥厚以及进一步出现心力衰竭后窦性心律震荡的变化及临床意义。方法:将94例高血压患者按照是否合并左室肥厚和心力衰竭分为三组,分析三组之间震荡起始(TO)和震荡斜率(TS)变化。结果:与单纯高血压组相比,高血压左室肥厚组TO增加(P<0.05);合并心力衰竭组TO增加更显著、TS减低,差异均有高度统计学意义(三组TO和TS比较,均P<0.01)。结论:高血压左室肥厚,尤其是合并心力衰竭患者窦性心律震荡减弱。窦性心律震荡可应用于高血压心脏损害相关人群猝死危险的评价。
Objective:To investigate the change and significance of heart rate turbulence(HRT) in patients with hypertensive left ventricular hypertrophy(LVH) and cardiac insufficiency.Methods:94 patients with essential hypertension were divided into 3 groups according to a merger of left ventricular hypertrophy and heart failure,and then analysis of turbulence onset(TO) and turbulence slope(TS) changes among the groups.Results:With the progress of LVH and heart failure,TO increased(P0.05) and TS decreased gradually,particularly in patients with heart failure(all P0.01) compared with the single hypertension group.Conclusion:There are gradually reduced HRT in patients with hypertensive LVH,especially those with heart failure.TO and TS could be applied to people with hypertension-related heart damage,and assess the risk of sudden death.
