应用24小时动态心电图检测108例心肌梗塞病人心率变异指数(HRVI),发现急性心肌梗塞病人HRVI在丽壁心梗者明显低于下壁心梗者(P<0.05)。HRVI在心肌梗塞病人中多部位梗塞明显低于单一部位梗塞(P<0.05),合并心力衰竭患者明显低于无心力衰竭患者(P<0.001),合并Lown氏分级Ⅱ级以上室性早搏患者明显低于其它患者(P<0.001)。经二年随访结果HRVI减低病人的死亡宰是HRVI正常病人的12.5倍。说明HRVI减低的心肌梗塞患者病情重,预后差。
The heart rate variability index (HRVI) was measured in 108 patients with myocardial infarction using 24-hour Holter monitoring. HRVI in patients with acute myocardial infarction was significantly lower than that in patients with inferior myocardial infarction (P <0.05). HRVI in patients with myocardial infarction was significantly lower than that of infarction at multiple sites (P <0.05), patients with heart failure were significantly lower than those without heart failure (P <0.001), and patients with Lown’s grade Ⅱ premature ventricular premature beats were significantly Lower than other patients (P <0.001). After two years of follow-up results HRVI reduce the patient’s death is 12.5 times the normal HRVI patients. Description HRVI reduced myocardial infarction patients with severe disease, the prognosis is poor.
