Inclusion criteria
Inclusion criteria: 1.18 years old = age = 75 years old 2.Patients with paroxysmal supraventricular tachycardia (AV reentrant tachycardia, atrioventricular nodal reentrant tachycardia, pre-excitation syndrome) who are scheduled to undergo catheter ablation treatment 3.Those who agree to participate in this study and voluntarily sign the informed consent form
Exclusion criteria
Exclusion criteria: 1. Patients who have previously undergone cardiac catheter ablation. 2. Patients confirmed to have other types of arrhythmias (e.g., ventricular arrhythmias, atrial flutter, atrial fibrillation) prior to intraoperative electrophysiological examination. 3. Patients with a left ventricular ejection fraction (LVEF) =40%. 4. Patients with confirmed intracardiac thrombus or diagnosed myxoma prior to surgery. 5. Patients with New York Heart Association (NYHA) functional classification III-IV. 6. Patients with an implanted pacemaker or cardioverter-defibrillator. 7. Patients who have undergone aortic valve replacement and require ablation via the retrograde transaortic approach during surgery. 8. Patients who have undergone atrial septal repair and require transseptal puncture for ablation during surgery. 9. Patients with active systemic infection deemed unsuitable for interventional treatment by the investigator. 10. Patients with a significant bleeding tendency that precludes surgery. 11. Patients with significant hepatic or renal dysfunction (ALT/AST, Cr levels >2 times the upper limit of normal) deemed unsuitable for surgery by the investigator. 12. Patients who have experienced myocardial infarction or undergone any cardiac interventional procedures (excluding coronary angiography) or open-heart surgery within the past 90 days. 13. Patients who have experienced a symptomatic stroke or other severe cerebrovascular events within the past 90 days. 14. Patients with a history of malignancy or terminal illness that would complicate treatment and evaluation. 15. Pregnant or lactating women, or those planning to conceive during the study period. 16. Patients currently participating in other clinical trials involving drugs or medical devices. 17. Patients deemed unsuitable for participation in this clinical trial by the investigator.
