简要总结
The purpose of this study is to compare the safety and effectiveness of cryoablation and radiofrequency ablation in the treatment of the commonest kind of supraventricular tachycardia, namely atrioventricular nodal reentrant tachycardia. The study hypothesis is that cryoablation is non-inferior to radiofrequency.
