Prevalence of atrial fibrillation in a regional Victoria setting, findings from the crossroads studies (2001–2003 and 2016–2018)

Abstract

Objective: To estimate the prevalence of atrial fibrillation (AF) in regional Victoria at two time points (2001–2003 and 2016–2018), and to assess the use of electrocardiogram rhythm strips in a rural, community-based study for AF investigation. Design: Repeated cross-sectional design involving survey of residents of randomly selected households and a clinic. Predictors of AF were assessed using Firth penalised logistic regression, as appropriate for rare events. Setting: Goulburn Valley, Victoria. Participants: Household residents aged ≥16 years. Non-pregnant participants aged 18+ were eligible for the clinic. Main outcome measures: Atrial fibrillation by 12 lead electrocardiogram (earlier ..
