Smartwatches could detect higher risk of heart failure: Study

A new study claimed Wearable devices such as smartwatches could be used to detect a higher risk of developing heart failure and irregular heart rhythms in later life. The peer-reviewed study, published in The European Heart Journal — Digital Health, looked at data from 83,000 people who had undergone a 15-second electrocardiogram (ECG) comparable to the kind carried out using smartwatches and phone devices. The researchers identified ECG recordings containing extra heartbeats which are usually benign but, if they occur frequently, are linked to conditions such as heart failure and arrhythmia (irregular heartbeats). They found that people with an extra beat in this short recording (one in 25 of the total) had a twofold risk of developing heart failure or an irregular heart rhythm (atrial fibrillation) over the next 10 years. The ECG recordings analysed were from people aged 50 to 70 who had no known cardiovascular disease at the time.
