【摘要】 目的:通过研究窦性心律震荡与急性心肌梗死患者再发心脏事件的关系,评价窦性心律振荡在急性心肌梗死患者再发心脏事件中的预测价值。方法:选择符合入选标准的40例急性心肌梗死患者和36例健康对照,收集入选者的24h动态心电图,计算窦性心律震荡的To、Ts指标。结果:急性心肌梗死组To升高、Ts降低,差异有统计学意义。急性心肌梗死患者再发组与无再发组比较,再发组To值高于无再发组,Ts值低于无再发组。结论:窦性心律震荡的指标在AMI患者及再发患者中都存在减弱现象,它们可以作为评价心肌梗死患者自主神经功能状态、再发心脏事件危险性预测的指标。更多还原

【Abstract】 Objective:To study the correlation of the heart rate turbulence about the accidence of cardiac events in AMI subgroup,and to assess clinical value of the indices of HRT in patients with the accidence of cardiac events in AMI subgroup.Methods:40 patients with AMI and 36 healthy controls were chosen.24 hambulatory eletrocardiograph(Holter),ultrasonic cardiogram(UCG) and clinical data were collected and processed to obtain the values of Turbulence onset(TO),Turbulence slope(TS).Results:The levels of age and TO in the patients with AMI were significantly higher than those of the controls,the levels of TS were lower than those of controls.The levels of TO in patients with the accidence of cardiac events in AMI subgroup were significantly higher than those of the controls in AMI subgroup,and the levels of TS were lower than those of the controls in AMI subgroup.Conclusions:Weaken HRT were observed in patients with AMI and the accidence of cardiac events in AMI subgroup.HRT can be used as some predictors in the accidence of cardiac events in AMI subgroup.更多还原
