When arrhythmia originates from the His bundle (HB) area conventional radiofrequency catheter ablation (RFCA) is associated with increased risk of atrioventricular block (AVB). Biophysics of bipolar RFCA (Bi-RFCA) suggest more selective lesion formation. It has been shown that Bi-RFCA can be an alternative in case of premature ventricular complex (PVC) or ventricular tachycardia (VT) refractory to standard RF. Whether Bi-RFCA can result in safe and effective ablation of PVC/VT originating from the close proximity of HB has not yet been investigated.
