Although elevated cardiac troponin is considered to be the gold standard biomarker for the identification of acute coronary syndrome, it may also occur in other clinical situations as supraventricular tachyarrhythmia (SVT) and acute coronary syndrome. We reported the case of a 77-year-old patient with a highly elevated cTn after the onset of SVT. Normal coronary arteries were detected through coronary angiography and intravenous ultrasound. It seems that the association of the cardiac troponin elevation in SVT patients with future cardiovascular events is very low. Meanwhile, more attention should be paid to those patients with high cardiovascular risk factors.
