Is there some kind of bracelet that can indicate, in addition to the heartbeat, if you have arrhythmia (atrial fibrillation)? Please note that I do not own a cell phone or a tablet. Thank you

Hello, it is difficult to detect atrial fibrillation at home without an electronic device powerful enough to generate the required information. There is a product produced by an American company called AliveCor which is installed behind a smart phone and can detect fibrillation simply by placing your fingers on the sensitive pads. Unfortunately, there is no bracelet that can detect AF without a Holter if you don't have a smartphone.
