A groundbreaking collaboration between researchers at Imperial College London and the British Heart Foundation (BHF) is set to transform how we detect dangerous, inherited heart conditions. By embedding advanced sensors directly into a comfortable, everyday garment, scientists have developed an “AI T-shirt” capable of monitoring the heart’s rhythm far longer and more accurately than traditional hospital tests.

Bridging the “Diagnosis Gap”

For many people with genetic heart disorders, such as Brugada syndrome, standard medical check-ups can be a source of false security. A typical hospital electrocardiogram (ECG) only records a 10-minute snapshot of the heart’s activity. Because many life-threatening rhythm abnormalities are intermittent—appearing and disappearing without warning—they are frequently missed during these brief windows.

The new smart T-shirt addresses this “diagnosis gap” by moving the laboratory to the patient’s home. Made from high-performance sportswear fabric, the shirt contains up to 50 integrated sensors that mirror a full ECG setup. Unlike bulky portable monitors that require adhesive pads and wires, this wearable can be worn comfortably while sleeping, working, or eating for up to a week at a time.

Harnessing the Power of AI

The secret to the shirt’s effectiveness lies in its artificial intelligence. The research team, led by Professor Zachary Whinnett, trained the AI algorithm using data from over 1,000 individuals. By analyzing millions of heartbeats, the AI has learned to recognize the subtle, “invisible” electrical patterns that signal a high risk of sudden cardiac death—patterns that might be imperceptible even to trained clinicians.

Real-World Impact and Future Potential

The project, backed by a £340,000 grant from the BHF, is currently undergoing a feasibility study with 200 volunteers at Hammersmith Hospital. For families like those affected by Brugada syndrome, which often runs in families and can strike young people without warning, this technology offers a new sense of hope.

“Far too many people die from inherited heart conditions that could be treated if identified earlier,” says Professor Whinnett. “We hope this AI-assisted T-shirt will provide a practical, comfortable solution that transforms our ability to spot these conditions.”

While the technology is initially being tested on adults, researchers believe it could eventually be adapted for children or used to monitor more common conditions like atrial fibrillation. Experts estimate that this smart wearable could become a standard clinical tool within the next five years, moving heart care out of the clinic and into everyday life.
