A New Hope for Early Detection of Inherited Heart Conditions
A revolutionary ‘smart T-shirt’ is set to transform the way heart conditions are diagnosed and monitored. Scientists have announced that this innovative garment could benefit hundreds of thousands of people by detecting hidden heart issues, particularly those that are inherited.
Currently, individuals experiencing symptoms like chest pain or dizziness often use a portable device to measure their heart’s electrical signals. This process involves sticky electrodes placed on the body, connected to a monitor worn around the waist. However, these devices require careful removal and reattachment when someone takes a shower, making them inconvenient and less practical for long-term use.
Now, researchers have developed a T-shirt embedded with up to 50 sensors stitched into the fabric. This new technology promises to be much simpler and more comfortable to use. The shirt, created through a collaboration between the British Heart Foundation and Imperial College London, is designed to detect rare, inherited heart conditions.
The smart T-shirt can be worn for up to a week, allowing for longer monitoring compared to traditional portable ECGs, which are typically used for one to two days. The data collected by the sensors is transmitted wirelessly to a computer, where an AI system analyzes the information and flags any potential issues for a doctor’s review.
This innovation could help around 340,000 people in the UK who have inherited heart conditions that may put them at risk of sudden cardiac death. These conditions can increase the likelihood of dangerous heart rhythms, which can be life-threatening if not detected early.
The Challenge of Diagnosis
Inherited heart conditions can significantly raise the risk of sudden cardiac death if they go undetected. It is estimated that 12 young people under 35 in the UK die each week from such conditions. These disorders can also cause symptoms like breathlessness or fainting during everyday activities, such as driving or exercising.
However, diagnosing these conditions in a hospital setting can be challenging, as heart rhythm tests and scans often appear normal. Professor Zachary Whinnett, a Cardiology expert at Imperial College London, emphasized the importance of early detection: “Far too many people die from inherited heart conditions which could be treated if identified earlier.”
He added, “One of the challenges of diagnosis today is that irregular heart rhythms may not always occur during routine 10-minute hospital ECGs or even 48-hour ECG monitoring at home. We hope our AI-assisted T-shirt will provide a practical and comfortable solution, allowing us to carry out longer-term scanning that could improve diagnosis.”
How the Smart T-Shirt Works
The T-shirt is designed to be comfortable and easy to wear, resembling sportswear. It can be worn underneath other clothes and is suitable for daily activities, including sleeping, eating, and working. The 50 sensors are strategically placed around the chest and heart area, functioning like an ECG to continuously monitor the heart’s electrical signals throughout the day.
Patients can wash the T-shirt as they would any regular clothing and wear it for up to a week. The data collected is transmitted wirelessly to a computer, where AI systems analyze the information to identify potential heart issues.
This technology is being developed with the support of Carly Benge, a 38-year-old teacher from Watford, who has Brugada syndrome—a dangerous heart rhythm disorder. Her two children, Imogen and Jake, are also at risk due to the genetic nature of the condition. Early diagnosis using the smart T-shirt could allow them to receive timely treatment and reduce their risk of sudden cardiac death.
Future Applications and Research
A prototype of the T-shirt will be tested on 200 patients and volunteers at Hammersmith Hospital’s Peart-Rose Research Unit. Participants will wear the T-shirt continuously for up to three months to evaluate its effectiveness in detecting serious heart conditions.
The design incorporates wires within the fabric to measure electrical signals, enabling longer monitoring periods. Researchers hope that the technology will be available for doctors to use within five years. While initially targeted at adults, if successful, the T-shirt could offer a more comfortable alternative for children in the future.
Additionally, the team aims to expand the application of this technology to help identify other heart rhythm conditions, such as atrial fibrillation, more effectively.
SADS: The Invisible Killer
Sudden Adult Death Syndrome (SADS) is caused by a ventricular arrhythmia, a disturbance in the heart’s rhythm. It can affect anyone, regardless of age or fitness level, and sometimes there are no warning signs. In some cases, individuals may experience dizziness or fainting spells, which can be triggered by physical or emotional stress.
SADS can be caused by underlying genetic disorders or acquired conditions. One in four cases is thought to be linked to ion channelopathies, which affect the heart’s electrical function without altering its structure. This means they can only be detected while a person is alive.
Although the exact prevalence of SADS is not fully known, research suggests it claims around 500 lives a year in Britain. It was first documented in 1977 among Hmong refugees in the US and later reported in Singapore, where medics found 230 healthy Thai men died suddenly between 1982 and 1990.
