Atrial fibrillation is a common heart condition. It occurs when the heart muscle does not properly contract and push the blood out of the heart's two upper chambers. Instead of a forceful contraction, the heart may flutter or not contact fully. It is the result of faulty electrical signals being sent to the heart. This leaves blood to pool in the heart chamber, which can lead to symptoms. While in many cases this condition does not cause serious illness, in other cases it can. If you recognize atrial fibrillation symptoms, see your physician to help rule out or prevent a more serious condition.
Rapid Pulse
The American Heart Association states that because the heart is not pumping as it should, your body may not be getting the blood and oxygen it needs. To help compensate, your heart will start beating faster and with an irregular rhythm to help deliver more blood. Your pulse may feel fast and erratic. You may also experience palpitations, which is an awareness of your heart beat or a pounding sensation in your chest.
Shortness of Breath
Since your heart is working harder and your body is not getting the right amount of oxygen-rich blood, you may have trouble catching your breath or feel like you've run out of breath. This may occur only during exertion, or in more severe cases, it can occur at rest as well. According to the National Institutes of Health, you may also become breathless when lying down. Atrial fibrillation can also make you feel tired and hinder your ability to participate in your usual activities. In addition, feeling tired and out of breath can leave you anxious and tense. If you suspect atrial fibrillation, your doctor can run tests to help confirm a diagnosis.
Chest Pain
In some cases, you may also develop chest pain as your heart works to maintain a normal rhythm. The National Heart, Lung and Blood Institute claim that chest pain or discomfort may also be accompanied by dizziness, sweating and a general sense of not feeling well. You may also suffer from fainting spells, confusion or general weakness. If your condition is severe, you may need medication to help prevent a heart attack, heart failure or stroke.
