| 摘 要： | 目的探讨冠心病患者的窦性心率震荡(HRT)及其与心率变异性(HRV)和室性早搏之间的关系。方法86例冠心病患者行24h动态心电图检查,计算机自动测定HRT的两个参数震荡初始(TO)和震荡斜率(TS)、HRV时域和频域指标及室性早搏数目。结果冠心病患者的HRT减弱,HRV降低,且TO与时域指标SDNN和SDANN及频域指标LF和LF/HF明显相关(p<0.05),TS与时域指标SDNN和RMSSD及频域指标HF和LF/HF及室性早搏数目明显相关(p<0.05)。结论冠心病患者的HRT现象减弱,且HRT与HRV及室性早搏数目明显相关。HRT应当是一种较HRV更好预测高危冠心病患者的无创性检查方法。

| Abstract: | Objective To investigate the association between heart rate turbulence(HRT),heart rate variability(HRV)and ventricular premature beats.Methods A 24-hour ECG Holter monitoring was performed to calculate two HRT parameters:turbulence onset(TO)and turbulence slope(TS),time-and frequency-domain HRV parameters and ventricular premature beats in 86 patients with coronary heart disease(CHD)and 60 controls without CHD.Results We found that the HRT and HRV parameters in patients were significantly lower than those i... |
