NCT ID NCT06271577
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new smartphone-connected 12-lead ECG device to see if it can accurately diagnose heart attacks (STEMI and NSTEMI) in people with chest pain. Researchers will compare the smartphone ECG readings to standard hospital ECGs in 1000 adults. The goal is to validate that the portable device works just as well as traditional machines, potentially enabling faster diagnosis in the future.
