Preclinical study demonstrates induction of complete atrioventricular block in dogs via high-frequency electrocautery, suggesting a viable method for cardiac ablation.
A new method is presented for the production of complete atrioventricular heart block. It consists of a special catheter, which is inserted into the right atrium via a femoral vein and positioned in the region of the His bundle for His bundle potential recording. Production of heart block is achieved by a high frequency current pulse from an electrocautery unit.
