The prognosis of dilated cardiomyopathy is generally poor. The cause of ventricular dysfunction often cannot be identified. In most cases, the clinical history of cardiomyopathy is irreversible but, in some cases, potentially curable causes may be identified. The development of cardiomyopathy may be correlated to atrial or to ventricular arrhythmias. In this scenario, atrial fibrillation is the most frequent cause of ventricular dysfunction, even if it may also be secondary to heart failure. The diagnosis of tachycardia-induced cardiomyopathy can be made only after the improvement of the left ventricular function once the cardiac frequency has slowed down.
扩张型心肌病的预后通常较差。心室功能障碍的病因往往难以确定。在大多数情况下，心肌病的临床病程是不可逆的，但在某些情况下，可能会发现潜在的可治愈病因。心肌病的发展可能与房性或室性心律失常相关。在这种情况下，心房颤动是心室功能障碍最常见的原因，即使它也可能继发于心力衰竭。只有在心率减慢后左心室功能改善时，才能做出心动过速性心肌病的诊断。
