Left Bundle Branch Block (LBBB) on ECG
Conditions
Brief summary
The electromechanical dyssynchrony induced by the presence of LBBB is in some patients, but not all, the cause of progressive left ventricular systolic dysfunction and heart failure. Aims 1. To investigate the clinical, ECG, imaging-derived features in a large cohort of patients affected by LBBB on ECG. 2. To identify predictors of LBBB-induced LV systolic dysfunction and predictors of outcome in this population. 3. To derive data which may have an impact on therapeutic management.
Interventions
