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。
Purpose Acute myocardial infarction is the most common cause of sudden cardiac death. Methods The occurrence of malignant ventricular arrhythmias and severe heart failure after acute myocardial infarction is the direct cause of sudden cardiac death. Results The combination of heart rate variability and heart rate oscillation can well reflect the balance between sympathetic and parasympathetic tone and reflect the regulation function of the heart itself. Conclusion According to abnormal changes of heart rate variability and heart rate oscillations, risk prediction of patients with high risk of sudden cardiac death after myocardial infarction can be carried out and the population needing ICD implantation can be identified to further guide clinical practice.
