Can troponin-I be used as an independent predictor of cardiac dysfunction after supraventricular tachycardia in children with structural normal heart?

Elevated cardiac troponin gives excellent accuracy in the identification of myocardial damage in children, but it can also be elevated in a series of other diseases. Case report We showed two children aged thirteen years with a high serum troponin-I after an acute episode of supraventricular tachycardia. We analyzed troponin-I levels in correlated with the maximum heart rate, duration of tachycardia and systolic left ventricular function (ejection fraction and fractional shortening). Conclusion Abnormal troponin level can be seen in children presenting with sustained supraventricular tachycardia and normal heart. Caution is advised in the diagnosis cardiac dysfunction in children with supraventricular tachycardia and elevated troponin levels.
