[Management of drug-resistant supraventricular tachycardia using AV-junction radiofrequency ablation].

The closed chest His bundle ablation is a worldwide accepted therapeutic method for the treatment of drug resistant supraventricular tachycardias. In the first years high-energy DC shock was applied for achieving the needed therapeutic effect. Reducing the complications caused by the DC shock, radiofrequency energy was introduced into the clinical practice. Authors describe the first successful human application of radiofrequency ablation of AV junction in Hungary.
