Digital Cardiology (e-Cardiology): useful tools for diagnosis and management of atrial fibrillation

Abstract

The mobile digital technology (mHealth), a tool still underutilized, has the potential to become an essential aid in clinical practice, particularly in Cardiology. Atrial fibrillation is the most frequent arrhythmia whose prevalence increases with age and its most feared complication is cerebrovascular accident. Its prevention depends on a timely diagnosis, an adequate risk stratification and the use of oral anticoagulants. However, it is frequently paroxysmal and asymptomatic, which makes its diagnosis difficult. The contribution of technology through the development of applications for cell phones, watches, portable or implantable devices that record the heart rhythm and allow prolonged, outpatient and remote monitoring, facilitate its detection. The main evidences that justify the application of these screening strategies are reviewed, when it is indicated to perform it, how and to whom to do it. Finally, the usefulness of these prolonged monitoring strategies in the management and prevention of atrial fibrillation is also considered.
