Off Their Trolley?

Atrial Fibrillation (AF) is an abnormal heart rhythm, that increases the risk of having a stroke. Circa 1 in 45 people (I'm one) live with this, often-undiagnosed, condition. It's been argued that some groups of potential AF carriers are 'hard to reach'. Most folk, however, are regulars at their local supermarket. A Liverpool John Moore's University study, recruited more than 2000 participants at a Sainsbury store. Participants were asked to hold a supermarket trolley handle for at least 60 seconds. Those handles had been fitted with electrocardiogram (ECG) sensors (https://www.theguardian.com/society/2023/jun/23/supermarket-trolley-sensors-ecg-atrial-fibrillation-stroke-trial-research). ECG sensor records gave an immediate indication (a tick or a cross) of whether the subject was likely to have AF. Subsequent detailed clinical diagnosis, confirmed that circa 40 of these participants had undiagnosed AF. There seems to be plenty of scope for reaching such people. It just needs a bit of ingenuity. Prevention is always better than a cure!
