Rapid Mapping of Right Atrial Tachycardia Using a New Multielectrode Basket Catheter

The mapping of atrial tachycardia (AT) can often be challenging and time‐consuming, especially in patients with ATs that develop following cardiac surgery or are concomitant with atrial fibrillation. Recently, a new multielectrode basket catheter (MBC) has become available; we hypothesized that the MBC could be utilized to diagnose AT circuits.
