BACKGROUND: Data are lacking on the characteristics of atrial activity in centenarians, including @entity616 ( @entity616 ). OBJECTIVE: The aim of this study was to describe the prevalence of @entity616 and @entity943 in subjects older than 100 years and to elucidate their clinical implications. METHODS: We studied 80 centenarians (mean age 101.4    1.5 years; 21 @entity1 ) with follow-ups of 6-34 months. Of these 80 centenarians, 71 subjects (88.8%) underwent echocardiography. The control group comprised 269 septuagenarians. RESULTS: A total of 23 subjects (28.8%) had normal P wave, 16 (20%) had partial @entity616 , 21 (26%) had advanced @entity616 , and 20 (25.0%) had @entity955 . The @entity616 groups exhibited premature @entity11706 more frequently than did the normal P wave group (35.1% vs 17.4%; P < .001); also, other measurements in the @entity616 groups frequently fell between values observed in the normal P wave and the @entity955 . These measurements included sex preponderance, mental status and @entity303 , perceived health status, significant @entity339 , and mortality. The @entity616 group had a higher previous @entity64 rate (24.3%) than did other groups. Compared with septuagenarians, centenarians less frequently presented a normal P wave (28.8% vs 53.5%) and more frequently presented advanced @entity616 (26.3% vs 8.2%), @entity955 (25.0% vs 10.0%), and premature @entity11706 (28.3 vs 7.0%) (P < .01). CONCLUSION: Relatively few centenarians (<30%) had a normal P wave, and nearly half had @entity616 . Our data suggested that @entity616 , particularly advanced @entity616 , is a pre-atrial fibrillation condition associated with premature @entity11706 . @entity943 and @entity616 occurred more frequently in centenarians than in septuagenarians.
