Although previous studies demonstrate that patients with atrial fibrillation AF refractory to rate-control are significantly impaired, quality of life QOL and physical capacity have yet to be adequately defined in rate-controlled AF patients. Older ambulatory adults were recruited from the Veterans Administration Medical Center VAMC in West Haven, Connecticut. Forty-seven patients with AF were enrolled from the Coumadin clinic, and an equal number of age-matched veterans in normal sinus rhythm NSR were enrolled from the Primary Care Practice PCP clinic. QOL was assessed by the widely-published Short Form Health Survey SF-36 which has been validated in older adult and veteran populations. The SF-36 produces two summary scales, the Physical Component Summary PC S and the Mental Component Summary MCS, which correlate positively with the level of physical and mental health QOL, respectively. Physical capacity was assessed by the Yale Physical Activity Survey YPAS, which has been validated in older adults. The YPAS produces a Summary Index, which
