努力提高心律失常性心肌病的认识和诊疗水平

摘要

心律失常性心肌病一直以来被定义为长期存在的心动过速损害左室功能，并导致心室扩大、心功能下降，最终引发心力衰竭的临床综合征；当患者的心率得到控制或快速性心律失常被纠正后，心功能可以部分或完全恢复，即心动过速性心肌病。随着心脏电生理的发展，人们发现能根治的心律失常种类越来越多，且不同类型的心律失常都能引起心肌病。因此，心动过速性心肌病的概念已发展和变化为心律失常性心肌病的概念。而各种类型心律失常性心肌病的引发机制不同，主要的治疗方法也不尽相同。%In the past,arrhythmia-induced cardiomyopathy has long been defined as a kind of clini-cal syndrome.Its pathogenic mechanism is long-standing tachycardia impairs left ventricular function which results in enlarged ventricle,declined cardiac function,and finally heart failure.After heart rate or tachyarrhythmia is controlled,cardiac function can be recovered partially or fully,and the clinical syndrome can also be called tachycardia-induced cardiomyopathy.With the progress of car-diac electrophysiology,more and more types of arrhythmias can be cured once and for all.Various types of arrhythmias are found which can induce cardiomyopathy.Therefore,the concept of tachy-cardia-induced cardiomyopathy has developed and been transformed into the concept of arrhythmia-induced cardiomyopathy.Different types of arrhythmia-induced cardiomyopathy differ in triggering mechanisms and mainstream therapies.
