Up to one-third of patients who received resynchronization devices do not experience the full benefits of CRT. The clinical factors influencing the likelihood to respond to the therapy are wide QRS complex, left bundle branch block, female gender, non-ischaemic cardiomyopathy (highest responders), male gender, ischaemic cardiomyopathy (moderate responders) and narrow QRS complex, non-left bundle branch block (lowest, non-responders) %K Echocardiography %K Resynchronization %K CRT %K Dyssynchrony %K Optimization %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5748829/
