Troponin elevation in supraventricular tachycardia: A narrative review

Figure 1 Flow diagram of study selection for the narrative review. A total of 135 records were identified through database searching (PubMed and EMBASE, 2000-2025). After screening of 27 records, 17 were excluded (2 pediatric studies, 1 including atrial fibrillation/flutter populations, 5 editorials/Letters to the editor, 5 case reports or small case series, and 4 review articles). Ten studies met the eligibility criteria and were included in the final narrative synthesis. AFL/AF: Atrial fibrillation/flutter.

ACS: Acute coronary syndrome; AT: Atrial tachycardia; AVNRT: Atrioventricular nodal re-entrant tachycardia; AVRT: Atrioventricular re-entrant tachycardia; CAD: Coronary artery disease; CCTA: Coronary computed tomography angiography; ECG: Electrocardiogram; PSVT: Paroxysmal supraventricular tachycardia.
