Ultra-high-density mapping for safe and effective typical atrioventricular nodal reentrant tachycardia ablation

Ultra-high-density mapping was used for potential-guided radiofrequency ablation for typical atrioventricular nodal reentrant tachycardia. The mapping detailed the spread of activation in the Koch's triangle and identified target potentials and tachycardia circuits. This mapping provides additional information to the slow pathway conventionally used for safe and effective ablation.
