Review of mobile applications for the detection and management of atrial fibrillation.

Background: Free mobile applications (apps) that use photoplethysmography (PPG) waveforms may extend atrial fibrillation (AF) detection to underserved populations, but they have not been rigorously evaluated.

Objective: The purpose of this study was to systematically review and evaluate the quality, functionality, and adherence to self-management behaviors of existing mobile apps for AF.

Methods: We systematically searched 3 app stores for apps that were free, available in English, and intended for use by patients to detect and manage AF.

Two Year Outcomes, Cognitive and Behavioral Markers of Decline in Healthy, Cognitively Normal Older Persons with Global Deterioration Scale Stage 2 (Subjective Cognitive Decline with Impairment).

Objective: Two-year interval behavioral markers were investigated herein.
