It does not provide a clinical diagnosis or treatment recommendation. Its optional AI feature is unvalidated for clinical use. The broad MI model class cannot determine whether an infarction is acute and cannot diagnose STEMI or coronary occlusion. A normal or indeterminate result cannot exclude disease or an emergency. Always use the original diagnostic-quality tracing, current guidelines, local protocols, and qualified clinical review. If someone may be experiencing a medical emergency, contact local emergency services immediately.
