心肌梗死后交感神经重构与室性心律失常

摘要

心肌梗死后存在交感神经变性、坏死和重构现象,而交感神经重构使室性心律失常和猝死的发生率增加.交感神经重构与电重构相互影响可能是心律失常发生的基础.对交感神经重构进行药物与非药物干预可能是控制心律失常发生的一个新的治疗途径.%Myocardial infarction induces cardiac nerve degenerating ,necrosis,regenerating and then remodeling. Sympathetic nerve reconstruction and electrical remodeling influence each other may be the foundation of the happened arrhythmia . The drug and non-drug inter- ventionon on sympathetic remodeling may be a new therapeutic approach to control the occurrence of arrhythmias .
