New radar technology advances heart rhythm detection

Contactless heart monitoring using radar and artificial intelligence could help doctors detect dangerous rhythm disorders earlier, without requiring patients to wear devices or visit hospitals.
Artificial intelligence and radio waves are being combined to spot hidden heart rhythm problems, offering a new approach to early detection beyond traditional medical tests.

Scientists have developed a radar-based sensor that detects irregular heart rhythms without physical contact. The system uses radio waves and AI to identify atrial fibrillation and allow earlier detection.

The technology was tested on more than 6,200 patients during routine heart checks. Results showed accuracy comparable to standard electrocardiogram tests, demonstrating its potential for clinical use.

Trials during sleep revealed that the system could detect hidden heart rhythm issues even when patients were at rest. Many episodes of atrial fibrillation go unnoticed at night, so this could improve early intervention.

Further studies will examine how the system performs in everyday life. Researchers hope these tests will show whether the technology can be used reliably outside clinics to monitor heart health.
