快速心室率、心律不规则以及非同步已被认为是心律失常诱导心肌病的主要病因,但患者通常进展到症状明显时才就诊,此时致病性心律失常可能已持续几个月甚至几年,导致心肌重构、舒张和收缩功能障碍.某些病例出现心律失常并在检查时一定出现的,必须治疗后才能对诊断进行回顾性证实.由于不同研究差异较大,严格的诊断标准难以确立.治疗包括药物治疗、导管介入治疗以及再同步治疗.治疗后大部分患者部分或完全恢复,并需严格随访监查复发且仍需要大规模随机对照试验,优化患者的危险分层和治疗策略.%Rapid ventricular rates, irregularity of heart rhythm, and asynchrony have been established as primary causes of arrhythmia-induced cardiomyopathy. Unfortunately, patients usually seek medical advice only when symptoms develop, while the causative arrhythmia may be present for months or years, resulting in myocardial remodelling, diastolic, and systolic dysfunction. In some cases, making a definite diagnosis may become a strenuous exercise for the treating physician, as the arrhythmia may not be present, additionally, therapy must be applied for the diagnosis to be confirmed retrospectively. The diagnostic process is also hardened due to the fact that strict diagnosing criteria still a matter of discrepancy. Therapy options include pharmaceutical agents, catheter-based therapies and resynchronization. For the majority of patients, partial or complete recovery is expected, although they have to be followed up thoroughly due to the risk of recurrence. Large, randomized controlled trials are more than necessary to optimize patients' stratification and therapeutic strategy choices.
