摘要 目的 :观察冠心病患者心肌缺血时的心率变异性 (HRV)变化。方法 :监测 38例冠心病患者 2 4h动态心电图中的 72次短暂心肌缺血发作事件 ,分析心肌缺血发作前、发作时、发作停止后的 HRV。结果 :在心肌缺血发作时 ,HRV降低。时域指标 SDANN ,r MSSD,PNN50 显著降低 ,频域指标 HF也降低 ,L F未见增加 ,L F/ HF无显著差异。结论 :在日常生活中发生的短暂缺血、迷走神经减弱可能起重要作用。 AIM:To observe the change of heart rate variability(HRV) on transient myocardial ischemia in coronary heart disease. METHODS:Detected seventy two ischemic episodes of 38 patients in 24 h Holter monitoring and analyzed parameters of HRV before,during and after transient ischemia. RESULTS:Depression of HRV was found during entire ischemia episode. SDANN,rMSSD,PNN 50 of HRV clearly decreased, so did HF in HRV spectrum analysis. LF and LF/HF didn't increase. CONCLUSION:The vagal depression may in influence onset of transient ischemia in daily life.
