When atrial fibrillation (AF) begins, it can start with a single focus, degenerating to multiple wavelets, and it spreads throughout the entire surface area of both atria. A fibrillatory wave that occurs at a rate of more than 600 beats per minute can cause fatigue in the long run, leading to atrial dilation.
