Atrial Fibrillation Detection Using Garmin Wearable Technology

• Conditions: Atrial Fibrillation
• Interventions: Device: Garmin Smart Watch; Device: Garmin Chest Band

• Registration Number: NCT03566836
• Lead Sponsor: University of Kansas Medical Center

Brief Summary

The purpose of this study is to evaluate the feasibility of detecting atrial fibrillation (AF) in patients with AF using a wearable wrist device/smart watch.

Detailed Description

Even though AF is common and associated with increased risk of stroke, quite often it goes undetected until late in the course of the condition. If AF can be detected with simpler tools like a smart watch, it would enable providers to identify patients with AF much earlier in the course of the condition (even before being seen by a physician) and hopefully be able to prevent stroke. This study is being done to identify a technology that can likely identify AF using a smart watch.
