Objective: In this study, we aimed to evaluate the characteristic of patients with supraventricular tachycardia for proper diagnosis and treatment in the Southeast Anatolian region. Methods: The study has a retrospective cross-sectional design. One hundred eighty-seven consecutive patients who underwent catheter ablation of SVT between June 2012 and April 2014 at the Dicle University Heart Hospital were included in the study. In those patients, in whom the arithmia substrate was identified, ablation therapy was carried out using radiofrequency (RF) energy. Results: Among SVTs 119 (63.6%) patients had atrioventricular nodal re-entry tachycardia (AVNRT), 20 (10.7%) patients had concealed atrioventricular re-entry tachycardia (AVRT), 40 (21. 4%) patients had Wolf Parkinson White (WPW) syndrome, and 8 (4.3%) patients had atrial tachycardia. RF ablation was applied on 184 patients. The overall RF ablation success rate was 96.2%. Overall recurrence was 8 (4%) of 187 patients during the follow-up period 12 ± 6 (1-23) months. The recurrence was 4 (3.4%) of 119 patients in AVNRT, 2(5%) of 40 patients in WPW syndrome and 2 (10%) of 20 patients in concealed AVRT. There was no statistically significant difference between groups in terms of recurrence. Two patients having AVNRT ablation died due to acute coronary syndrome in clinical follow-up. Conclusion: The acute and long-term success rates of SVT ablation were in accordance with literature. The other characteristics of SVT were similar to the current data.
