A wearable heart monitor worn for just 14 days could help spot life-threatening heart problems sooner.
New BHF-funded research found that quickly fitting a chest-worn monitor to people attending A&E with unexplained fainting more than doubled the detection of heart rhythm problems. After one year, heart rhythm problems were identified in 22% of people using the monitor, compared to 9% receiving standard care.
For Stephen, 68, from West Lothian, the faster monitoring made all the difference. Despite living with atrial fibrillation for almost 20 years, standard checks in hospital couldn't explain why he had suddenly fainted. He went home and fainted again the next day, which resulted in a 3 day hospital stay where his nurse asked if he wanted to join the trial.
After joining the trial, Stephen wore the chest monitor for 14 days. Although he didn't experience another fainting episode while wearing it, the device revealed that his atrial fibrillation wasn't being controlled by his medication. At certain points, his heart was beating at a dangerously high 227 beats per minute.
Thanks to the monitor picking up the problem, Stephen's care team were able to adjust his treatment. Since then, he hasn't fainted again. "I'm very glad I took part in the trial and that this was picked up," Stephen said. "I haven't fainted since, it looks like the treatment has been working, so I'm really happy."
Stephen's story highlights the potential of two-week heart monitoring from when a patient goes to A&E, which can uncover serious heart rhythm problems that may not be detected during routine hospital tests and later monitoring. This can help more people get the treatment they need sooner.
