    Optimized single-point left ventricular pacing leads to improved resynchronization compared with multipoint pacing 
    San Antonio, Rodolfo; Guasch, Eduard; González-Ascaso, Ana; Jiménez-Arjona, Rafael; Climent, Andreu M.; Pujol-López, Margarida; Doltra, Adelina; Alarcón, Francisco; Garre, Paz; Liberos Mascarell, Alejandro; Trotta, Omar; Quinto, Levio; Borras, Roger; Arbelo, Elena; Roca-Luque, Ivo; Atienza, Felipe; Brugada, Josep; Fernandez-Aviles, Francisco; Guillem Sánchez, María Salud; Sitges, Marta; Tolosana, José María; Mont, Lluis (Blackwell Publishing, 2021-03)
    [EN] Background Multipoint pacing (MPP) in cardiac resynchronization therapy (CRT) activates the left ventricle from two locations, thereby shortening the QRS duration and enabling better resynchronization; however, compared ...
