Not enough QRS shortening? Keep calm and add another lead Jiménez-López, Jesús Vallés Gras, Ermengol Alcalde Rodríguez, Oscar Benito Villabriga, Begoña Cabrera Gómez, Sandra Martí-Almor, Julio Cor -- Malalties -- Tractament Infart de miocardi Fibril·lació auricular Cardiac resynchronization therapy (CRT) diminishes symptoms and reduces hospitalization and mortality in patients with heart failure, LV dysfunction and left bundle branch block. However, up to one third of patients do not respond to CRT. In that regard, few initial studies presenting multisite pacing have shown encouraging results, demonstrating both feasibility and safety in placing a second CS lead in >80% of patients intended, with further QRS shortening, which is the most powerful predictor of LV reverse remodelling. 2016-12-05T07:52:44Z 2016-12-05T07:52:44Z 2016 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Journal of Clinical Case Reports. 2016;6:789 © 2016 Jiménez-López J, et al.
