Eko Foundation Analysis Software with Transformers (EFAST) vs Us2.v2
Similar category, different focus. These tools serve overlapping but distinct needs.
Comparability 65/100
Comparability is an AI-graded 0–100 score of how directly these two tools compete — higher means a more apples-to-apples comparison.
AI Verdict
EFAST assists clinicians with real-time structural murmur and atrial fibrillation detection during auscultation using digital stethoscopes. In contrast, Us2.v2 automates the interpretation and reporting of echocardiograms, providing comprehensive structured reports for a wider range of cardiac conditions. Therefore, EFAST is suited for point-of-care screening, while Us2.v2 streamlines advanced diagnostic imaging analysis.

Frequently Asked Questions
EFAST by Eko Health assists clinicians in real-time during routine exams by identifying structural murmurs associated with heart disease and detecting atrial fibrillation using Eko digital stethoscopes. Us2.v2 by Us2.ai automates the interpretation of echocardiograms, delivering complete structured echo reports with measurements, disease detection, and clinical findings.
EFAST requires seamless integration with Eko digital stethoscopes and offers EMR integration for streamlined documentation. Us2.v2 is compatible with any ultrasound manufacturer and integrates seamlessly with existing PACS, CVIS, or EMR systems, supporting HL7 and DICOM SR.
EFAST is designed for AI-powered structural murmur detection and AI-powered atrial fibrillation (AFib) detection. Us2.v2 automates the detection of cardiac amyloidosis, aortic stenosis, heart failure, pulmonary hypertension, and valvular disease through echocardiogram analysis.
EFAST provides real-time AI analysis during auscultation, enhanced audio, and waveform visualization, aiming for smarter cardiac care in seconds. Us2.v2 aims to reduce reporting time by up to 70% and increase daily scan throughput through 100% AI automation of echocardiogram interpretation.
EFAST reports 93% sensitivity and 91% specificity for structural murmur detection, and 95% sensitivity and 94% specificity for AFib detection. Us2.v2 states it makes heart risk detection more accurate and consistent but does not provide specific sensitivity or specificity figures for its disease detection capabilities.
