Smartwatch nudges aim to get AF patients moving more

This study tests whether a smartwatch and text message system can encourage people with paroxysmal atrial fibrillation (a type of irregular heartbeat) to be more physically active. The trial has two phases: first, a small group will help design the messages and test the smartwatch; second, 40 participants will either get the smartwatch system or standard care. The goal is to see if this approach is practical and helpful for a larger future study.
