Tachycardia-induced cardiomyopathy (TIC) is a well recognized entity of heart failure (HF) and various mechanisms due to tachyarrhythmias have been postulated to be responsible for impaired cardiac contractility. Previously reported cases showed reversibility of such disorders whenever stable cardiac rhythm is maintained adequately and we report on a 16-year-old boy who has been diagnosed to have TIC, which was misinterpreted initially as sinus tachycardia secondary to dilated cardiomyopathy and heart failure. A complete recovery of his left ventricular function was achieved by radiofrequency catheter ablation and highlights the importance of a 12-lead electrocardiogram (ECG) assessment in such patients.
心动过速性心肌病（TIC）是一种已被充分认识的心力衰竭（HF）类型，据推测，各种由快速性心律失常引起的机制与心脏收缩功能受损有关。先前报道的病例显示，只要能充分维持稳定的心律，此类疾病具有可逆性。我们报告了一名16岁男孩，他被诊断患有TIC，最初被误诊为继发于扩张型心肌病和心力衰竭的窦性心动过速。通过射频导管消融，他的左心室功能完全恢复，这突出了对此类患者进行12导联心电图（ECG）评估的重要性。
