Premature Atrial Contraction

1. "To our knowledge, this is the first study to assess risk factors for PAC [Premature Atrial Contraction] frequency in the general population aged ≥50 years. PACs are common, and their frequency is independently associated with age, height, history of cardiovascular disease, natriuretic peptide levels,[and inversely with] physical activity, and high-density lipoprotein cholesterol."
