Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and paroxysmal AF (PAF) comprises approximately half of all AF cases. PAF poses a particular diagnostic challenge given its intermittency. A physician's choice of investigational device is largely based on symptom frequency although it has been widely established that a significant proportion of PAF episodes are asymptomatic. We aim to determine whether symptom frequency is a reliable method to select a choice of investigational device in a population presenting with palpitations.
