Twenty-six patients with paroxysmal supraventricular tachycardia were treated with radiofrequency catheter ablation, including 17 cases of atrioventricular bypass (5 cases of dominant type A pre-excitation syndrome, 10 cases of occult left bypass, Syndrome in 2 cases), a total of 18 atrioventricular bypass, of which 10 on the left side of the wall, left after the interval of 6, right after the interval of 2. 9 cases of atrioventricular node dual pathway patients were used to block the slow pathway.
