Is Eko FDA cleared? What is the DUO ECG + Digital Stethoscope? The DUO is a pocket-sized cardiac examination system used to electronically amplify, filter, and transfer body sounds and single-lead electrocardiogram (ECG) waveforms. It facilitates timely care for patients in and out of the clinic. By combining ECG and auscultation, clinicians get more information at a glance without disrupting workflow or running costly tests. DUO is an FDA-cleared device that helps clinicians capture, transmit, and analyze electromechanical information in as little as 15 seconds from the clinic or the comfort of patients’ homes. The latest generation of DUO is optimized for a wireless workflow through enhanced Bluetooth connectivity with most wireless listening devices. This allows clinicians to assess patients freely and untethered. DUO can be purchased with removable earpieces that can be used like a traditional stethoscope to meet any provider’s preferences. When paired with the Eko App, DUO supports Automated AFib, murmur, tachycardia, and bradycardia detection (currently only available in the U.S.). 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. Who is the DUO designed for? 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: Physicians PAs and NPs Nurses EMTs and first-responders Veterinarians Home health providers What are the differences between the 1st and 2nd generation DUO? The 2nd generation DUO offers improved ECG quality, sound quality, Bluetooth signal strength, and battery performance. Its enhanced connectivity simplifies the workflow for clinicians who prefer to perform exams wirelessly. The 2nd generation DUO can also be purchased with earpieces for clinicians who prefer to use DUO like a traditional stethoscope. What’s the difference between buying the DUO with or without earpieces? You may choose to purchase 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 the DUO earpiece, wired headphones, or audio cable. DUO supports wireless listening with most Bluetooth headphones, hearing aids, and other audio devices. Even if you purchase DUO with an earpiece, you can detach the earpiece and connect to a Bluetooth-enabled device at any time. Is the DUO analog or digital? The DUO is only a digital stethoscope and can't be used in analog mode like the Eko CORE Digital Attachment or 3M™ Littmann® CORE. What is Eko analysis or automated detection software? Eko analysis software, or Eko AI, is FDA-cleared software that includes screening algorithms to assist clinicians in detecting suspected murmurs and AFib. Important Eko AI analysis is currently only available in the U.S. We're actively working on offering it in other countries. 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 summarizes 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. To learn more, see the Eko analysis software user manual. What are the electrodes on the DUO made of? 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. Can the DUO be used with a pacemaker or ICD? DUO hasn't been tested for accuracy with ECG recordings taken from users with pacemakers. We can't recommend DUO for users with pacemakers or ICDs because we can't guarantee the accuracy of the resulting ECG readings. Can the DUO attach to my analog stethoscope? No. The Eko CORE Digital Attachment is the only product compatible with analog stethoscopes. Can the DUO be used in pediatrics? Yes. The indication for use for the DUO is for patients over 10kg. How does the DUO work for Bluetooth or wireless listening? The DUO provides wireless functionality using Bluetooth technology when using the Eko App for iOS and Android. It pairs with Bluetooth-enabled headphones, hearing aids, and speakers. To learn more, see Set up wireless listening for hearing loss or headphones. Can I use the DUO on animals? Yes, the DUO is used by veterinarians on both small and large animals. Many veterinarians use Eko for sound amplification, wireless listening, telemedicine, and even recording sounds to increase engagement with pet owners. 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 3M™ Littmann® CORE Digital Stethoscope or Eko CORE Digital Attachment. Important Eko automated murmur detection is not intended to be used on animals. Tips for ECG readings for animals: Wet the fur with water. Use ECG gel if wetting the fur doesn't help. Always use the DUO on the least hairy spots. Under the armpits usually works. Shave the hair in the area where you'll be placing the DUO. Does the DUO help with hearing loss? There are three main ways the DUO supports clinicians with hearing loss: Amplified sounds help users hear low frequency sounds more clearly. Visualizing sound waveforms (phonocardiograms) on the Eko App helps the user confirm the sounds they are hearing. The Eko App pairs with Bluetooth-enabled hearing aids, cochlear implants, and streaming devices. To learn more, see this section of our Help Center: Wireless listening and hearing loss support. View our Stethoscope Guide for Healthcare Workers with Hearing Loss and watch a video explaining how to configure the Littmann CORE Digital Stethoscope with different types of hearing aids. What is the warranty and return policy? See these policies: Returns Warranty Is the DUO compatible with the Eko App and platform? Yes, the DUO pairs with the Eko App. Download the Eko App for free (for iOS from the Apple App Store, and for Android devices from the Google Play Store). The primary features of the Eko App are: Automated murmur, tachycardia, and bradycardia detection (currently only available in the U.S.). 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) Capture and share recordings. What is the battery life of the DUO? The DUO can last up to 10 hours of continuous use on a full charge and has up to 1-year standby time. Is the DUO FDA cleared? Yes, the DUO and Eko Analysis Software is FDA cleared and CE marked.
