Eko DUO ECG + Digital Stethoscope

When the Eko App is connected and used with a compatible digital stethoscope, Eko’s FDA-cleared software automatically checks for murmurs and/or AFib during Cardiac Exam or Spot Check. (The Eko DUO ECG + Digital Stethoscope is required for Afib detection).

The Eko App will summarize any findings, including potential murmurs, AFib, or other abnormalities detected. These findings aren’t a diagnosis, but are intended to aid the clinician in reaching a diagnosis accurately, quickly, and confidently.

You may choose to use DUO with or without the included removable earpieces. There are no limitations or compromises on utility or performance with either option.

DUO comes with a threaded 3.5 audio jack that accepts DUO earpiece, wired headphones, or audio cable. DUO supports wireless listening with most Bluetooth headphones, hearing aids, and other audio devices.

The Eko DUO ECG + Digital Stethoscope comes with a 2-year warranty which is warranted against any defects in material and workmanship.

All stethoscopes purchased on the Eko website are backed by a 100% refundable, 75-day trial. We offer free returns within 75 days of receiving your stethoscope.

The DUO is often used in rural or small clinics that don’t have readily available ECG machines, community screenings, home health, or any virtual/telehealth settings. Clinicians that benefit most from the DUO need quick access to a portable ECG for a complete heart assessment.

Recommended for:

• Primary care
• Family medicine
• Internal medicine
• Cardiology
• Home health
• Emergency medicine
• Geriatrics
• Nephrology

Within these settings, clinician users include MDs, DOs, NPs, PAs, RNs, and LPNs.

Yes, we encourage students to use Eko stethoscopes to learn auscultation skills and how to identify heart, lung, and body sounds.

Yes, the DUO supports wireless listening to most Bluetooth headphones, hearing aids, and devices.

Alternatively, DUO is fitted with a threaded 3.5mm audio jack, so you can directly connect headphones or other streaming devices.

Yes, the DUO can be used by veterinarians on both small and large animals. However, the DUO’s form factor was optimized for human patients — automated murmur and AFib detection are not intended to be used on animals.

If you only need digital stethoscope functionality, we suggest the Littmann CORE Digital Stethoscope or Eko CORE Digital Attachment.

Tips for ECG readings on animals:

1. Wet the fur with water

2. Use ECG gel if wetting the fur doesn't help

3. Always use the DUO on the least hairy spots (under the armpits)

4. Shave the hair in the area

Eko digital stethoscope technology supports clinicians with hearing loss in several ways:

• Sound amplification helps users hear low-frequency sounds more clearly
• Waveform visualization (phonocardiograms and electrocardiograms) on the Eko App helps confirm the sounds heard and electrical signals seen
• Bluetooth compatibility allows stethoscopes to be paired with hearing aids or wireless streamers

Yes the DUO can be used in pediatrics, but the indication of use is for patients over 10kg.

Yes, the Eko CORE, Eko DUO, and Eko Analysis Software are FDA cleared and CE marked.

The DUO can last up to 10 hours of continuous use on a full charge and has up to 1-year standby time.

The two ECG electrodes are made of stainless steel. They are designed to work dry — that is, without any gel or cream. However, gels or creams can improve the signal quality in some situations.

DUO has not been tested for accuracy with ECG recordings taken from users with pacemakers. We cannot recommend DUO for users with pacemakers or ICDs because we cannot guarantee the accuracy of the resulting ECG readings.
