miAfib vs HeartScan

The mobile application (miAfib) will assess symptoms and effect on multiple occasions throughout the day using the mobile phone. Only participants in the research study will be able to use the mobile application. The study team will do initial setup of the application for all participants. The application will capture the user's input, which will be transferred back to University of Michigan Medical School (UMMS) where they can be used for reporting and research.

Meet HeartScan — the first phone‑only heart‑rate monitor that shows what your smartwatch can’t. Lay back, place the iPhone on your chest, hold still for 60 s.

Open HeartScan and hit Start. Place the phone mid‑sternum or apical region. Breathe normally for one minute. Review BPM, wave, rhythm and HRV.
