Abstract

Atrial fibrillation (AF) is the most common sustained cardiac dysrhythmia encountered in practice. It is currently estimated that AF affects approximately 2% of the general population; however, the true prevalence of AF is likely to be at least 3%–4% when asymptomatic AF is considered. For clinically apparent AF, the investigations and management are relatively well established. The identification of minimally symptomatic patients is challenging, and furthermore, the optimal management is less certain. Although there is some debate about the ideal treatment pathway for asymptomatic AF, in most cases, the investigations and comprehensive management follow the same recommendations as clinically apparent AF. In contrast, beyond risk factor optimisation, the ideal management of subclinical or device-detected AF remains undefined. The purpose of the current review is to discuss the assessment and management of asymptomatic AF.
