Atrial fibrillation (AF) is a very common problem. In England alone, approximately 835,000 people have AF. This number is rising rapidly, and prevalence is predicted to double by 2050. This reflects the rising prevalence of risk factors, such as hypertension and obesity as well as being a consequence of population ageing. In this podcast, Dr Thomas Round, a GP and EKU Clinical Lead, talks to Dr Nicholas Jones, a GP and GP cardiologist in Oxford, with an active interest in cardiovascular disease and atrial fibrillation about the diagnosis and management of atrial fibrillation.
