摘要
目的急性心肌梗死是最常见的导致心源性猝死的病因。方法发生于急性心肌梗死后的恶性室性心律失常及严重的心力衰竭是导致心源性猝死的直接原因。结果心率变异和心率振荡相结合能很好的反应交感神经与副交感的平衡状况,并能反映心脏自身的调节功能。结论根据心率变异和心率振荡的异常改变,能对心肌梗死后具有心源性猝死高危因素的患者进行风险预测,并能确定需要植入ICD的人群,进一步指导临床实践。
Objective Acute myocardial infarction is a very common cause of sudden cardiac death (SCD). Methods The malignant ventricular arrhythmia and serious heart failure were the direct cause of sudden cardiac death. Results There are good indications for evaluating the balance between sympathetic nerve and parasympathetic nerve by using heart rate variability and heart rate turbulence. And it can reflect the function of cardiac automatic regulation. Conclusions According to the abnormal of heart rate variability and heart rate turbulence, we can identify the patients at high risk of sudden cardiac death after acute myocardial infarction and identify the patients who need implantable cardioverter defibrillator (ICD).
