Atrial fibrillation was associated with significantly lower peak oxygen uptake (15.7 vs 17.7 ml/kg/min) compared to heart rate-matched sinus rhythm controls during cardiopulmonary exercise testing.
Observational (n=133)

Does atrial fibrillation influence oxygen uptake and exercise tolerance in cardiovascular patients?
Atrial fibrillation exaggerates detrimental heart rate increases during exercise in cardiovascular patients, which may impair exercise tolerance.
Absolute Event Rate: 15.7% vs 17.7%
p-value: p=0.004
pulse above the AT level was strongly associated with the detrimental response of HR increase and the response was markedly exaggerated in the AF patients.
Takano et al. (Tue,) conducted a observational in Cardiovascular disease (heart failure or ischemic heart disease) (n=133). Atrial fibrillation vs. Heart rate-matched sinus rhythm was evaluated on Peak oxygen uptake (VO2/kg) in ml/kg/min (p=0.004). Atrial fibrillation was associated with significantly lower peak oxygen uptake (15.7 vs 17.7 ml/kg/min) compared to heart rate-matched sinus rhythm controls during cardiopulmonary exercise testing.
