Summary

This study tests whether a compact 3-lead ECG device can accurately detect acute coronary syndrome (heart attack) in adults arriving at the emergency department with chest pain. Participants receive a HeartBeam ECG recording within 10 minutes of the standard 12-lead ECG. The goal is to compare the device's sensitivity and specificity against the gold-standard diagnosis.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
HeartBeam 3-dimensional 3-lead ECG system
What this could lead to
If successful, this portable ECG could enable faster, more accessible heart attack detection in emergency settings.
What could go wrong
This is a small pilot study, so results may not confirm the device's accuracy. The system is for research only and not yet used for patient care.
