The ability to accurately self-monitor conditions with confidence at home has the potential to ease the number of people requiring trips to hospital, which could be particularly useful during the COVID-19 pandemic.The technique is currently being used as the basis for a new Artificial Intelligence approach that can detect QT-interval lengthening automatically. Self-monitoring is particularly useful when someone starts taking a new form of medication, as they will be able to contact their doctor as soon as they notice an issue. The more warm colors you can see, the greater the risk of long QT syndrome.Long QT syndrome often doesn't cause symptoms, so an ECG is the only way to pick it up. A spectrum of color is applied to the area under the ECG signal from blue to red. The newly developed technique works on a "single lead" ECG, which is the heart reading available on a smart watch. Empowering people to understand and monitor their own ECG is a huge leap forward for public health, as it will reduce the number of times people have to go into hospital for routine check-ups, and ensure they get emergency medical attention as soon as they need it." Here, we've shown that it is simple for lay people to understand when they might be at risk of long QT syndrome, which is important because it is caused by many common medications and can result in sudden death. We now have evidence that if you display an ECG in the right way, it can easily be interpreted by a patient. Caroline Jay from The University of Manchester said: "For decades we've assumed that only medical experts can interpret ECGs. Researchers at The University of Manchester have been working on a novel visualization technique that makes it straightforward for members of the general public to understand ECG data.ĭr. It is vital for detecting cardiac pathologies, but extremely difficult to interpret, even for clinicians. The longer it gets, the more likely you are to suffer from a life-threatening arrhythmia that can cause sudden death.Īn ECG shows complex signal data representing the heart's electrical activity. Many common medications, including some prescribed for depression and cancer, can cause this to lengthen. The "QT-interval" is the time it takes for the heart to depolarise and recharge itself. In new research published today in journal PLoS One, scientists show that if you apply color in the right way, people can easily monitor hospital-level health data themselves. Previously people needed to have an ECG in hospital that was interpreted by a highly-trained expert. University of Manchester researchers have developed a simple technique that allows people to monitor their own electrocardiogram (ECG) for a potentially life-threatening condition.
