Objective: Cardiac resynchronization therapy (CRT) is an effective option in the treatment of patients with heart failure and wide QRS. Presence of fragmented QRS (f-QRS) on 12-lead electrocardiogram (ECG) has been shown to be associated with non-response to CRT. The aim of this study was to evaluate whether onset of fragmentation (Q-f interval) is important for CRT response.
