Troponin I elevation after supraventricular tachycardia in a child with hypertrophic cardiomyopathy.
An 11-year-old patient with diagnosis of hypertrophic cardiomyopathy (HCM) developed marked elevation of troponin I in the absence of electrocardiographic signs of ischemia after two episodes of supraventricular tachycardia. At follow-up the level of troponin I returned to normal. The role of troponin I in patients with HCM as a risk marker deserves further evaluation.
