Poor physical activity performance. People with atrial fibrillation find it hard to do physical exercises. They may get tired doing the first five minutes of intensive training. It can be defined as an exercise intolerance, and it prevents the patients from achieving the healthy physical shape. A daily activity like going shopping may be a real challenge for the people with this disorder.

It may be too hot in summer, but there is no reason to go too sweaty every hour or several minutes. Some people sweat more than an average person should even without intensive training or exercises. They may start sweating when it’s not that hot outside. Most of the time, this symptom is associated with the atrial fibrillation and problems with heart functionality.
