摘要:
本文应用24 h动态心电图对健康人(对照组) 和冠心病心绞痛、心肌梗死患者进行心率变异性研究。结果发现: 心绞痛组和前壁心梗组的正常RR间期总体标准差(SDNN)、每连续5 min时段正常RR间期均值的标准差(SDANN ) 及其平均值(SDNN index)、心率总功率(TP)、极低频功率(VLF)、低频功率(LF) 和高频功率(HF) 等均低于对照组(均P < 0.01) ; 下壁心梗组的SDNN , SDNN index和L F 低于对照组(均P<0.05) ; 前壁心梗组的SDNN,SDANN 和LF低于心绞痛组(均P<0.05)。心率变异诊断冠心病的阳性标准取低于对照组上述任一项指标95% 区间下限值, 则其特异性为93. 9% , 心绞痛组敏感性为51. 2% , 心梗组为71.4%。提示心率变异下降对冠心病的诊断有一定的参考价值。
Abstract:
The time domain and frequency domain of heart rate variability (HRV )were studied in patients with coronary heart disease and normal controls from 24 hour electrocardiography.The results showed that SDNN , SDANN , SDNNindex , TP, VLF, LF and HF were markedly decreased in 41 patients with angina pectoris (Anginas) and 17 patients with acute anterior myocardial infarction (AAMIS) compared with 33 controls (allP< 0.01).SDNN , SDNNindex and LF were reduced in acute inferior myocardial infarction (AIMIS) compared withcontrols(all P<0.05). SDNN , SDANN and LF were reduced in AAMIS compared with Anginas. The abnormality of HRV were diagnosed if the value of any index was lower than the threshold (x-1.96s of controls).The specificity of the diagnosis standard was 93.9%,its sensitivity was 51.2% in Anginas, 71.4% in AMIS. These results indicate that the impairment of autonomic nervous system function are associated with degree of myocardial injury and HRV might be taken as a diagnostic indicator.
