Circulation: Arrhythmia And Electrophysiology On The Beat

Dr Paul Wang:                   Welcome to the monthly podcast, On the Beat for Circulation: Arrhythmia and Electrophysiology. I'm Dr Paul Wang, Editor-in-Chief, with some of the key highlights from this month's issue. In our first paper this month, Shaan Khurshid and associates determine the frequency of rhythm abnormalities in 502,627 adults in the UK Biobank, a national prospective cohort. They found that 2.35% had a baseline rhythm abnormality. The prevalence increased with age, with 4.84% of individuals aged 65 to 73 years having rhythm abnormalities. During over three million person- years of follow up, nearly 16,000 new rhythm abnormalities were detected. Atrial fibrillation was the most frequent with three per thousand person-years. Bradyarrhythmia with almost one per thousand person-years. Conduction system disease is about one per one thousand years. Supraventricular and ventricular arrhythmias, each about one half per one thousand person-years. Older age was associated with a hazard ratio of 2.35 f
