Eko DUO ECG + Digital Stethoscope

When the Eko app is connected and used with a compatible digital stethoscope, the FDA-cleared Eko Analysis Software (EAS) automatically checks for murmurs and/or AFib during Cardiac Exam or Spot Check recordings.

Once the recording is completed, the Eko app will summarize any findings, including potential murmurs, atrial fibrillation, or other abnormalities detected. Keep in mind that the algorithms used to detect murmurs or AFib are not accessed by an Eko device alone. Users must be connected to the EAS using the newest version of the Eko app.

In clinical studies, Eko detected heart murmurs with 88% sensitivity and 88% specificity. When compared to the performance of trained cardiologists, Eko’s detection accuracy was comparable to that of human experts.

Reminder: the outputs of the Eko analysis are not a diagnosis but are intended to aid the clinician in reaching a diagnosis accurately, quickly, and confidently.

DUO was designed with the versatility to listen and assess the way you want. You may choose 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.

Clinicians tell us that the DUO is a great handheld screening device with stethoscope functionality. The ideal clinician that benefits most from DUO needs quick access to a portable ECG for a complete heart assessment. 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.

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

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

Here are some tips to ensure you are getting the highest quality ECG readings for 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 usually work)

4. Shave the hair in the area

There are three ways Eko stethoscopes support clinicians with hearing loss.

1. Sound amplification helps users hear low frequency sounds more clearly.

2. Visualizing waveforms (phonocardiograms and electrocardiograms) on the Eko App helps confirm the sounds you are hearing and electrical signals you are seeing.

3. Pairing with your stethoscope Bluetooth-enabled 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.

Yes, the Eko DUO ECG + Digital Stethoscope pairs with the Eko App. Download the Eko App for free at the iOS and Android app stores.

The primary features of the Eko App are:

• Automated murmur, AFib, tachycardia, and bradycardia detection
• Spot check that analyzes in just 15 seconds
• A guided 4-point assessment to maximize accuracy
• Unlimited recordings accessible from any device
• Easy report generation and sharing
• Heart sound visualization (PCG)
• Electrocardiogram visualization (ECG)
• Wireless listening over Bluetooth

Eko stethoscopes and software are purpose-built for telemedicine. Eko supports virtual care or telehealth programs for individual providers, small clinics, and multi-site hospitals. A subscription may be required for telemedicine live streaming.

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.
