Summary

This study tests whether a smartphone app (DigitHeart-2) can accurately predict heart structure and function from a simple ECG picture. About 478 adults who need an echocardiogram will have their ECG photo analyzed by the app, and the results will be compared to the standard ultrasound. The goal is to see if this technology can provide a quick, accessible way to assess heart health.
