Detect what is often overlooked with the leading Cardiac AI

Sound is a rich and accurate source of medical information about how the heart is functioning in that moment. Heart sounds provide true indications of blood flow through the heart, as well as the timing and functioning of valves opening and closing.

Structural and rhythmic issues often manifest early as subtle murmurs or irregular beats.

Stethophone PRO not only enhances these sounds for improved medical listening, but also helps visualize and identify anomalies that can easily be missed during routine examinations.

The AI powering this technology is trained on millions of recorded heart cycles and thousands of hours of medical expert insights, enabling it to learn what to listen for. The Stethophone AI is acquiring 200 years of human auscultation skills built on the world’s largest databank of heart sounds.

Medical-level heart sound recording

Important heart sounds are often quiet or occur at frequencies on the edge of human perception. Stethophone has patented advanced bioacoustics that make heart sounds clearer and more audible than leading medical stethoscopes that cost thousands.

With Stethophone, your phone is your personal stethoscope.
Just hold it to your body, listen with headphones and hit record.
Atrial Fibrillation (AF) is the most common cardiac arrhythmia in humans, is associated with increased morbidity and mortality, and has become a public health problem of the first order. From: Cardiac Electrophysiology: From Cell to Bedside (Sixth Edition), 2014

Point-of-Symptom listening and analysis

Doctors and medical technicians can’t always be on hand to catch symptoms as they occur. Each year, millions of people experience cardiac issues that go unnoticed and unobserved. For thousands, this can mean the difference between receiving timely care and waiting months or even years for an accurate diagnosis and treatment plan. Stethophone grabs the empirical medical data you need from your heart at the moment you are concerned.

Medical grade reviewing tools

A leading set of medical analysis tools allow doctors to understand and confirm results.

  • Heart sounds are visualized, segmented and measured for timing
  • Playback speeds can be adjusted and sound filters applied
  • Recording quality is checked and displayed
