Кратко
Atrial fibrillation (AF) is the most common arrhythmia (irregular heart rhythm), affecting 1-2 million people in the UK. AF significantly increases the risk of an AF-related stroke, heart failure and dementia. A significant proportion of people will have no symptoms, and they may only be found to have AF after suffering an AF-related stroke. An electrocardiogram (ECG) uses sensors placed on the skin to record the heart's electrical activity. A 12-lead ECG uses 10 sensors and is the gold-standard (best available test) to detect any abnormal heart rhythm disturbances. Until recently, a 12-lead ECG showing an irregular heart rhythm was required to make a diagnosis of AF but as AF episodes are often short and unpredictable it may be missed. Therefore, a small device that continuously records heartbeat and heart rhythm could make the diagnosis of arrhythmias and AF much quicker and easier. Accessories such as watches or rings - referred to as wearable devices - have extremely good sensors that measure pulse rate by detecting small changes in skin colour during each heartbeat and can perform a single-lead ECG. Algorithms built in the wearable devices can identify irregular heart rhythms,
