Paul J. Wang: Welcome to the monthly podcast, On the Beat for Circulation: Arrhythmia and Electrophysiology. I'm Dr. Paul Wang, editor in chief, with some of the key highlights from this month's issue.   In our first paper, Vivek Reddy and associates studied a novel, 7.5, French lattice tip catheter with the compressible 9 mm nitinol tip that is able to deliver either focal radio frequency ablation [RFA] or pulsed field ablation [PFA], 2 to 5 second lesions. In a 3 center, single-arm, first in human trial, the catheter was used with a custom mapping system to treat paroxysmal or persistent atrial fibrillation. Toggling between energy sources, point by point, pulmonary vein [PV] encirclement was performed using biphasic pulsed field ablation, posteriorly, and either temperature controlled irrigated RFA or pulse field ablation, anteriorly (RF/PF or PF/PF) respectively. Linear lesions were created with either PFA or RFA. The 76 patient cohort included 55 paroxysmal and 21 persistent atrial fibrillation [AF] pati
