A recent study indicates that smartwatches from brands like Apple, Google, and Samsung, equipped with an electrocardiogram (ECG) sensor, are a better tool for detecting dangerous heart rhythm disorders compared to traditional medical tests. The study, conducted by the Amsterdam University Medical Centers, focused on atrial fibrillation, the most common heart rhythm disorder in the world. This condition often occurs irregularly and does not cause noticeable symptoms in many people. Led by cardiologist Michel Winters and PhD student Nicole van Steen, the research investigated whether wearable devices, such as smartwatches, can help detect these disorders earlier and more accurately than current traditional methods. In the case of atrial fibrillation, the heart's atria beat irregularly, which can lead to blood clots forming in the heart. If these clots travel to the brain, they may cause a stroke.
