Purpose: This systematic review’s aim is to evaluate the role of autonomic markers in predicting supraventricular tachycardia (SVT) recurrence after catheter ablation. Understanding these markers can help to identify patients at higher risk of recurrence and improve post-procedural management. Methodology: A full literature review has been conducted using 12 electronic databases, such as PubMed, ScienceDirect, Springer, MDPI and Oxford Academic. It has covered studies in English from 1999 to 2025. The PRISMA 2020 guidelines for systematic reviews have been followed in the review. Studies have been chosen using the PICO framework: adult patients with SVT who undergo catheter ablation (Population), evaluation of autonomic markers like heart rate variability (HRV), baroreflex sensitivity (BRS), skin sympathetic nerve activity (SKNA), and P-wave alternans (Intervention), comparison with normal or baseline values (Comparator), and recurrence or non-recurrence of SVT as the outcomes (Outcome). Both qualitative and quantitative data were extracted, including statistical measures such as odds ratios, hazard ratios and predictive accuracy metrics. Findings: HRV is the most studied and widely applied autonomic marker. Early post-ablation HRV changes correlate with recurrence risk in AF studies, but evidence in SVT is limited and largely hypothetical. BRS, SKNA and PWA have showed potentiality but have been underexplored in SVT. Clinical and procedural factors, such as accessory pathway location and ablation strategy, is influencing the recurrence rates. In Bangladesh, HRV has been measured in tertiary centers, while other markers are not routinely applied due to resource constraints. Conclusion: Autonomic markers have promising potential to predict SVT recurrence, but no robust SVT-specific studies are there. Future research should focus on multicenter prospective studies with standardized measurement protocols and integration of clinical factors to develop reliable predictive models.
