DOI: 10.1016/j.ccep.2020.02.004
Abstract: High-density (HD) mapping presents opportunities to enhance delineation of atrial fibrillation (AF) substrate, improve efficiency of the mapping procedure without sacrificing safety, and afford new mechanistic insights regarding AF. Innovations in hardware, software algorithms, and… read more here.

DOI: 10.1016/s0735-1097(19)30934-9
Abstract: Non-contact electro-anatomical mapping enables global mapping of the entire cardiac chamber of interest. A novel non-contact mapping system, which records intracardiac voltage to derive cellular charge sources (dipole density), may allow real-time mapping of atrial… read more here.
