Figure Lengend Snippet: Comparison between minibipolar voltage mapping using the multipolar mapping catheter (PentaRay) (Bip), and microbipolar voltage mapping using microelectrodes on the ablation catheter’s (QDOT Micro) tip (MicroBip). Although low-voltage regions are recorded by bipolar mapping using a multipolar catheter, electrogram recorded by microelectrodes have normal amplitude in the same regions.
