“How is atrial fibrillation usually diagnosed?”
My mother has atrial fibrillation, but I'm just wondering how this condition is usually diagnosed in patients. How is it detected?

ECG usually but if it's intermittent then Holter monitor can be used.
Prolonged monitoring is the key. This can be achieved initially by a portable 30-day event monitor and if atrial fibrillation detected and the suspicion is still high then an implantable small monitors are used these are called "Loop Recorders" like the Medtronic Linq device. These devices can record the heart beats 24/7 for up to 3 years and transmit data remotely to your physician on a daily basis.
