目的探讨心绞痛型冠心病的心率震荡现象。方法将105例拟诊为心绞痛型冠心病的患者按照冠状动脉造影结果分为冠心病组和对照组,冠心病组53例,对照组52例。每例患者均做24h动态心电图检查,取得心率震荡(HRT)参数:震荡初始(TO)和震荡斜率(TS)。比较二组间TO、TS的原始数值、二组间TO、TS异常的阳性率以及按照HRT异常分级比较二组间各级构成。结果冠心病组的TO明显大于对照组、TS明显小于对照组,冠心病组的TO、TS异常的阳性率明显高于对照组,二组间的HRT异常分级各级构成比差异有统计学意义。结论心绞痛型冠心病患者的心率震荡现象明显减弱或消失。
Objective To investigate the heart rate turbulence of angina pectoris coronary heart disease. Methods A total of 105 cases of patients with angina pectoris type CHD were divided into coronary heart disease group and control group according to the results of coronary angiography. The coronary heart disease group was 53 cases and the control group was 52 cases. Each patient underwent 24-hour Holter monitoring and HRT parameters were obtained: initial shock (TO) and concussion slope (TS). The original values of TO and TS were compared between the two groups. The positive rates of TO and TS abnormalities between the two groups were compared, and the levels of the two groups were compared according to the abnormalities of HRT. Results The TO in CHD group was significantly higher than that in control group, the TS was significantly lower than that in control group, the positive rate of TO and TS abnormalities in CHD group was significantly higher than that in control group, and there was significant difference between the two groups . Conclusion The heart rate turbulence in patients with angina pectoris is significantly reduced or disappeared.
