Read the full statement (145 words)

The Eko Foundation Analysis Software with Transformers (EFAST) is intended to support healthcare professionals in the

evaluation of patients’ heart sounds and electrocardiograms (ECGs). The software calculates heart rate, detects the

presence of murmurs associated with Structural Heart Disease, and determines murmur timing including the timing of S1,

S2 heart sounds. When ECG is available, the software detects the presence of atrial fibrillation and normal sinus rhythm.

The software is intended for use by or under the supervision of a healthcare professional and is not to be used as a sole

means of diagnosis. The interpretations of heart sounds and ECG offered by the software are designed to support and not

replace the healthcare professional’s clinical judgment. The murmur detection is intended for use on both pediatric and

adult patients, while the detection of atrial fibrillation is intended for use on adults (> 18 years).

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
