Does Cardiac-Resynchronization Therapy reduce the rate of death or hospitalization for heart failure in patients with systolic heart failure and a QRS duration of less than 130 msec?
In patients with systolic heart failure and a narrow QRS complex (<130 msec), CRT does not improve clinical outcomes and may increase mortality, indicating it should be avoided in this population.
