Overview
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
- To investigate the clinical, ECG, imaging-derived features in a large cohort of patients affected by LBBB on ECG.
- To identify predictors of LBBB-induced LV systolic dysfunction and predictors of outcome in this population.
- To derive data which may have an impact on therapeutic management.
Eligibility
Inclusion Criteria:
- LBBB on ECG
Exclusion Criteria:
- Previous extensive anterior myocardial infarction
- Previous cardiac surgery or transcatheter aortic valve implantation (TAVI)
- Congenital structural heart disease
- Patients implanted with permanent right ventricular stimulation devices and permanent pacing
- Denial to consent
