Case Reports: Changes of high-sensitive troponin level in a patient with paroxysmal supraventricular tachycardia

High sensitive troponin (hsTn) assays offer great opportunities to diagnose acute myocardial infarction (AMI). The demonstration of rise and/or fall of troponin (Tn) with at least one value about the 99th percentile upper than the reference limit as well as the evidence of myocardial ischemia are necessary to diagnose AMI. These days the frequency of Tn positivity in the non-acute coronary syndrome has increased resulting in more overcrowding of emergency departments. It is evident that AMI is a clinical rather than a biological diagnosis and a physician should consider the clinical content. In this study, the specific pattern of hsTn change in a patient admitted with chest pain, paroxysmal supra-ventricular tachycardia (PSVT) and ST segment depression in electrocardiogram (ECG) without coronary artery disease (CAD) would be introduced.
