心动过速性心肌病的研究进展

Research Progress of Tachycardia-induced Cardiomyopathy

长期快速性心律失常可引起心室扩大和心室收缩功能障碍,即心动过速性心肌病。早期应用药物或导管消融可控制或消除心律失常,心脏扩大和心功能障碍可部分或完全恢复正常,即心动过速性心肌病是可逆性的。现就心动过速性心肌病的发病机制、诊断、治疗及预后作如下阐述。

Tachycardia may lead to cardiac dilation and cardiac insufficiency, which is tachycardia-induced cardiomyopathy. Early controlling or eliminating the culprit arrhythmia using pharmacological or ablative techniques result in partial or complete recovery of cardiac dilation and insufficiency, and that is reversible. The mechanisms, diagnosis, therapeutic strategies and prognosis about arrhythmia-induced cardiomyopathy are following.
