Abstract

 

Introduction. 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 presented two children thirteen years of age with a high serum level of troponin-I after an acute epi­sode of supraventricular tachycardia. We analyzed troponin-I levels in correlation 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 with sustained su­praventricular tachycardia and normal heart. Caution is ad­vised in diagnosing cardiac dysfunction in children with su­praventricular tachycardia and elevated troponin levels.
