Effect of atrial high-rate episodes (AHREs) on functional status and quality of life (QoL) in heart failure—cardiac resynchronization therapy population

AHRE significantly reduces functional status and perceived quality of life in HFrEF patients receiving CRT. Longer than five minutes of AHRE was associated with a higher MLHFQ score and worse performance on the 6MWT. In that patient population, smoking, obesity, and elevated LAVI were independent predictors of AHRE.
