Patterns of ventricular dyssynchrony in congestive heart failure- comparison with controls and implications for patient selection for cardiac resynchronization therapy.
Assessment of ventricular dyssynchrony by Tissue Doppler Imaging (TDI) is being increasingly used in patient selection for Cardiac Resynchronization Therapy (CRT). Regional distribution of dyssynchrony has been sparingly addressed in dyssynchrony studies in heart failure population. ⋯ LVD is distributed amongst HF patients with narrow or wide QRS and with LBBB or RBBB with a similar regional distribution. Dyssynchrony in normal individuals with bundle branch block is in the form of septal delay. These findings may have implications for patient selection for CRT and site of LV pacing.
