AI-Powered Heart Murmur Detection with eMurmur® Heart AI and ri-sonic® Electronic Stethoscope (AI Stethoscope)

Revolutionizing Cardiac Auscultation

Cardiac auscultation has been a cornerstone of heart defect screening for over 200 years. Despite its long history, accurate diagnosis remains a challenge due to faint heart sounds, breathing, high heart rates, and the difficulty of distinguishing between innocent and pathological murmurs. Traditional auscultation relies entirely on the subjective interpretation of the examiner.

Introducing eMurmur® Heart AI and ri-sonic® Electronic Stethoscope 

We are proud to integrate eMurmur® Heart AI with our ri-sonic® electronic stethoscope AI stethoscope, combining cutting-edge AI technology with superior auscultation capabilities. This integration enables healthcare professionals to screen, monitor, diagnose, and consult on heart, lung, and bowel health, whether the patient is in clinic, in hospital, or at home.

eMurmur, the advanced digital auscultation software

eMurmur is available in the Google Play Store and in the App Store.
