title: [Radiofrequency ablation and cardioneuroablation for AVNRT and atrioventricular block].
abstract: We describe a case of a 35 year-old woman with AVNRT and AVB successfully treated with radiofrequency ablation. Prior to the procedure, PR interval was very prolonged (420 ms) and second degree Wenckebach AV block during sinus rythm with heart rate below 80/min was seen. After the successful RF ablation an improvement in atrio-ventricular conduction with disappearance of Wenckebach periodicity was achieved. This case shows that there is a possibility of successful elimination of slow pathway with improvement in AV conduction.
