致心律失常性右室心肌病(arrhythmogenic right ventricular cardiomyopathy,ARVC)多伴有不同程度的心脏功能障碍,最终可导致心力衰竭和恶性室性心律失常,甚至心脏性猝死(sudden cardiac death,SCD),严重危及患者的生命。近来研究较多的是起源于右室的室性心律失常发生机制。本文就ARVC的心律失常基质做一简要综述。
Arrhythmogenic right ventricular cardiomyopathy(ARVC),which may lead to heart failure and malignant ventricular arrhythmia ultimately,even sudden cardiac death(SCD),endanger the patients' life seriously.More recent studies mainly relate to the mechanisms of ventricular arrhythmias originated from the ventriculus dexter.In this paper,the cardiac arrhythmia substrates of ARVC are reviewed.
