肥厚性心肌病患者的心率震荡检测结果分析

Analysis of Results of Heart Rate Turbulence Detection in Hypertrophic Cardiomyopathy

目的:探讨肥厚性心肌病(HCM)患者心率震荡(HRT)现象的特征及其临床意义。方法:选择50例HCM患者(HCM组)及50例健康人群(对照组),均接受24h动态心电图检查,分别计算HRT的震荡初始(TO)及震荡斜率(TS),并比较两组患者TO及TS均值。结果:HCM组的TO及TS值与对照组比较差异无显著性(P>0.05)。结论:HCM患者HRT无明显异常。

Objective, To study the characteristics and clinical significance of heart rate turbulence （HRT） in patients with hypertrophic cardiomyopathy （HCM）. Methods： Fifty patients with HCM （HCM group）and fifty control subjects （control group） were examined by 24 hours Holter monitoring. HRT onset （TO） and slope （＇IS） were calculated from Holter records. TO and TS were compared between the two groups. Results, There were no significant differences in TO and TS between the HCM group and control group. Conclusion. There were no significant differences in HRT between HCM group and control group.
