and/or atrial tachycardia (AT) in heart failure (HF) patients provides
improvement in symptoms cardiac function and survival. However, these

compare outcomes of AF/AT ablations guided by an ultra-high density
mapping system between HF patients and controls. Methods and
results: Primary endpoint was the one-year rec… Show more
