急性心肌梗死(AMI)易导致心源性死亡,早期准确识别出AMI中的高危患者,才能有针对性地选择治疗和预防措施。本文通过观察AMI患者心率震荡(HRT)的震荡起始(TO)与震荡斜率(TS)指标、心率变异性(HRV)的时域指标(SDNN)与心率变异三角指数(HRVTI),以及常规超声心动图,包括左房舒张末期前后径(LAED)、左室舒张末期前后径(LVED)、左室射血分数(LVEF)和短轴缩短率(LVFS)等指标,以探讨对AMI患者心源性死亡具有较高预测价值的指标与方法。1对象与方法
Acute myocardial infarction (AMI) easily lead to cardiac death, early accurate identification of high-risk patients with AMI, to targeted treatment and preventive measures. In this paper, the heart rate turbulence (TS), heart rate variability (HRV) time-domain index (SDNN) and heart rate variability trigonometry index (HRVTI) Cardiogram, including left atrial diastolic anteroposterior diameter (LAED), left ventricular end-diastolic anteroposterior diameter (LVED), left ventricular ejection fraction (LVEF) and short axis shortening (LVFS) and other indicators to explore the AMI patients with cardiac Indicators and methods of sexual death with high predictive value. 1 objects and methods
