Abstract :
BACKGROUND: Tachycardia-induced cardiomyopathy (TIC) is a rare cause of dilated
cardiomyopathy (DCMP). The diagnosis can be missed because tachycardia is a common
symptom in DCMP.
CASE REPORT: We reviewed a case 5-year-old with palpitation and dyspnea with symptoms and
signs of heart failure that diagnosed as DCMP initially. Then, in the evaluation for cause of
tachycardia, atrial tachycardia was detected. Hence, treatment with flecainide was started and
after 3 months, left ventricular (LV) systolic function and symptoms of the patient was relieved.
CONCLUSION: TIC should be suspected in all patients with unexplained LV dysfunctions in the
setting of a persistent tachyarrhythmia.
