Abstract: Arrhythmogenic cardiomyopathy is a special type of cardiac diseases， its etiopathogenesis is mainly due to the emergence of fast or slow arrhythmiainduced hemodynamic changes， it first appears in electrical remodeling of myocardium followed by myocardial mechanical remodeling. Arrhythmogenic cardiomyopathy performed diversely with mainly manifested as atrial heart failure， and others mainly manifested as ventricular heart failure， at present， the study of arrhythmia cardiomyopathy is gradually deepened， treatment methods increased gradually， but mainly include drug therapy and interventional therapy. In this review， we discussed the molecular mechanisms of atrial and ventricular cardiomyopathy in order to improve the cure rate of this disease.

Key words: arrhythmias, cardiac；cardiomyopathies, heart , atria; , heart , ventricles
