Frequency of Cardiac Rhythm Abnormalities in a Half Million Adults.

ABSTRACT:

Background

The frequency of cardiac rhythm abnormalities and their risk factors in community-dwelling adults are not well characterized.

Methods

We determined the frequency of rhythm abnormalities in the UK Biobank, a national prospective cohort. We tested associations between risk factors and incident rhythm abnormalities using multivariable proportional hazards regression.

Results

Of 502 627 adults (median age, 58 years [interquartile range, 13]; 54.4% women), 2.35% had a baseline rhythm abnormality. The prevalence increased with age with 4.84% of individuals aged 65 to 73 years affected. During 3 368 332 person-years of follow-up, 15 906 new rhythm abnormalities were detected (4.72 per 1000 person-years; 95% confidence interval [CI]: 4.65-4.80). Atrial fibrillation
