The patient was a 39-year-old female with recurrent paroxysmal, regular narrow QRS complex tachycardia. The cryoablation attempts (-80°C, 240 second) were performed in the inferior–posterior triangle of Koch’s. We observed several junctional beats during cryoablation, After successful cryoablation, AVNRT induction was repeatedly checked during a waiting period of 30 minutes. In our case we demonstrated that junctional beats can be observed during cryoablation. A junctional beats occurring during cryoablation of AVNRT is described for the first time.
