AI ECG Interpretation

An electrocardiogram records electrical activity from the heart. AI software can process the waveform to classify rhythms or flag patterns that may be associated with a condition. Some cleared systems analyze standard 12-lead ECGs to support screening for a specified finding; others analyze ambulatory rhythm recordings. These products have different inputs and purposes. FDA documentation for a low-ejection-fraction algorithm, for example, describes a defined screening aid used with clinician judgment, not a stand-alone diagnosis or patient-monitoring service. An AI flag can help a clinician decide whether additional evaluation is warranted, but ECG interpretation depends on context. Signal noise, lead placement, rhythm, medication, prior conditions, and device compatibility can affect performance. A negative result does not rule out disease in every person; a positive result may require echocardiography or another appropriate test. Some device labeling excludes particular inputs, such as paced rhythms, or limits use to a defined adult group. Follow the exact device instructions. Patients should ask what the result means, what the algorithm was designed to detect, and whether follow-up is needed. Clinicians and health systems should verify FDA authorization, validate the integrated workflow, review source tracings, and monitor false alerts and missed cases. An algorithm should not replace emergency assessment, a clinician’s interpretation, or communication with the patient. Document what to do after positive, negative, and unreadable results.
