Serum troponin testing in patients with paroxysmal supraventricular tachycardia: outcome after ED care

Changes of high sensitive troponin level in a patient with paroxysmal supraventricular tachycardia

“…In a recent published study, by 51 PSVT cases, 11 of them had a positive Tn test. Furthermore one month follow up showed no PSVT recurrence or death for these patients (2). This study confirms our opinion, considering further evaluation of troponin in SVT patients.…”

Usefulness of laboratory and radiological investigations in the management of supraventricular tachycardia

“…It was not surprising, therefore, that the troponin was elevated in approximately one‐third of our patients in whom it was measured. Importantly, an elevated troponin in patients with SVT does not necessarily predict AEs or poor outcomes …”

Cardiac troponin I elevation with supraventricular tachycardia: two case reports and review of the literature

“…Most authors are in agreement with the mechanism that tachycardia increases myocardial oxygen demand, while it decreases myocardial oxygen delivery because of short diastole during which myocardial perfusion occurs. So tachycardia ultimately leads to reduced myocardial perfusion which results in the release of cTnI into the circulation [4]. …”

“…This question has different answers. Calberg and his colleagues made a retrospective review of 51 patients with PSVT, 38 of whom had cTnI value meassured at least one time [4]. Eleven patients having elevated cTnI were followed up for thirty days.…”

“…A high cTnI level however is not synonymous to ACS [3]. Patients with normal coronary arteries may have elevated cTnI because of other diseases such as severe congestive heart failure, myocarditis, cerebrovascular accident, renal insufficiency and so on [4]. Since 2003 it has been reported that patients suffering from paroxysmal supraventricular tachycardia (PSVT) had elevated troponin levels [5].…”
