Versatile tool for frontline clinicians

DUO is a pocket-sized, smart detection system that can be used as a stethoscope and point-of-care ECG to identify signs of heart disease such as murmurs and arrhythmias in and out of the clinic. Use DUO to quickly check for cardiac pathology during normal auscultation to help determine if further workup is needed. FDA-cleared software enables clinicians to capture, transmit, and analyze electromechanical cardiac data in as little as 15 seconds — from the clinic or the comfort of patients’ homes.

View or live stream ECG tracings and sound waveforms directly from your mobile devices with just a few taps. DUO is purpose-built for wireless listening and telemedicine, making it ideal for clinicians who need to be mobile or work in non-clinical environments. Automated disease detection, powered by FDA-cleared, clinically-proven algorithms help clinicians detect early signs of cardiac conditions with comparable accuracy to human experts.‍
