"Discovery2" Study of Using MCG at Emergency Departments

Open to people ages 22 years and up

• Women and men aged 22 years and older
• Participant presenting with signs and symptoms suggestive of NSTE-ACS
• In ED chest pain/NSTE-ACS care pathway

• Unable to provide informed consent

• Active arrhythmia (as seen on the most recent ECG) such as atrial fibrillation, atrial flutter, ventricular tachycardia
• Acute hemodynamic instability
• Inability to lie supine and still for 5-10 minutes
• Known or suspected pregnancy
• Unable or unwilling to comply with required follow-up

• Active implantable medical devices (e.g. pacemakers, neurostimulators.. etc.)
• Active illegal drug use per history of present illness
• Contraindicated for temporary removal of telemetry during MCG scan
• Clear non-ischemic cause for symptoms (e.g. trauma, viral infection, valve disease)
• Clinical conditions that in the opinion of the Investigator would compromise the safety of the participant or ability to complete the protocol (e.g., exceeds bed weight limit, allergy to adhesives)
