According to researchers in the UK, new generation of AI powered stethoscope could transform the way doctors detect life-threatening heart conditions.
A study led by Imperial College, London and Imperial College Healthcare NHS Trust found that the AI-enabled device can identify heart failure, heart valve disease, and abnormal heart rhythms within seconds. Experts are calling a potential “game-changer,”
The updated model replaces chest piece with a sensor about the size of a playing card. Using a microphone, it records subtle differences in heartbeat and blood flow that are imperceptible to the human ear. The device simultaneously performs an electrocardiogram (ECG), sending the data to the cloud, where it is analyzed by AI trained on tens of thousands of patient cases.
Dr Sonya Babu-Narayan, clinical director at the British Heart Foundation and a consultant cardiologist, described the innovation as “an elegant example of how the humble stethoscope, invented more than 200 years ago, can be upgraded for the 21st century.” She stressed that early detection is critical: “Too often, these conditions are only identified at an advanced stage when patients present in emergency settings. With earlier diagnosis, people can access treatment sooner and live well for longer.”
The findings were presented at European Society of Cardiology’s annual congress in Madrid, the world’s largest cardiology gathering. Following the successful trial, plans are underway to introduce the AI stethoscopes to GP practices in south London, Sussex, and Wales.
