Outcomes of PFA Vs. RFA for Patients with PSVT: a Retrospective and Propensity Score Matching Study

The Safety and Efficiency of Pulsed Field Ablation and Radiofrequency Ablation in the Treatment of Paroxysmal Supraventricular Tachycardia：a Retrospective and Propensity Score Matching Study

The goal of this retrospective study is to compare the long-term follow-up outcomes of pulses field ablation (PFA) Vs. radiofrequency ablation (RFA) for the patients with paroxysmal supraventricular tachycardia (PSVT). The main question to answer is:

Does the PFA was more effecient and safer that RFA for treatment of PSVT during procedure and after 1-year follow-up? Researchers will compare the acute and long-term efficiency and safety between PFA and RFA.

1. Recieved PFA or RFA 1 year ago
2. Finish the visit to the clinic at 1, 3, 6, 12 months for examinations and blood testings
3. Patients recieved PFA and PFA under propensity matched comparison according to differen variety of PSVT

The goal of this retrospective study is to compare the long-term follow-up outcomes of PFA Vs. RFA for the patients with PSVT. The main question to answer is:

Does the PFA was more effecient and safer that RFA for treatment of PSVT during procedure and after 1-year follow-up? Researchers will compare the acute and long-term efficiency and safety between PFA and RFA.
