冷冻消融术是利用冷冻标测和冷冻粘结技术,具有(1)通过电传导特性的改变可观察消融的有效性；(2)紧贴靶点,防止移位,避免损伤房室传导组织；(3)消融过程中不出现结性心律,使观察房室传导更精确；(4)在标测过程中出现的房室传导阻滞都是可逆的特点,使冷冻消融术在治疗房室结折返性心动过速时与射频消融相比有其无法比拟的优势。 Cryoablation is the use of frozen mapping and cryoablation techniques, with (1) the effectiveness of ablation can be observed through changes in electrical conduction characteristics; (2) close to the target to prevent displacement, to avoid damage to atrioventricular tissue; (3) no arrhythmia during ablation, the observation of atrioventricular conduction more accurate; (4) in the mapping process of atrioventricular block are reversible features of the cryoablation in the treatment of atrioventricular node Reentry tachycardia and radiofrequency ablation compared to its incomparable advantages.
