Shortness of Breath
Atrial fibrillation often causes shortness of breath [4]. When you are short of breath, you may feel like you cannot get enough oxygen into your lungs or are unable to properly utilize the oxygen you are taking in. You may find yourself trying to inhale more deeply each time you breathe or inhaling new air even before completing your last exhale. The severity of this symptom varies from person to person.
Shortness of breath can reduce your ability to exercise [5] or participate in endurance sports. You will often find yourself getting tired quickly and having to take more breaks to catch your breath. You may also be unable to lie down flat on your back without feeling like you are running out of adequate air. It reduces your overall life quality.
