Atrial fibrillation, otherwise known as AFib, is a health condition that can be related to more serious issues. If you have AFib, you are among 2.7 million Americans diagnosed with the conditions, according to the American Heart Association. Generally, an arrhythmia disorder is not life-threatening. However, if you are suffering from AFib, there is a likelihood that an underlying issue or condition can be correlated. Take a look at 10 effects AFib may have on your body. 

Muscle Weakness

A healthy heart is able to provide blood and oxygen to the rest of your body at a consistent rate. This oxygen supports muscle function, so a heart with an arrhythmia disorder will result in muscle weakness. This can be identified as a lack of strength or a shortened endurance.

Heart Palpitations

When your heart skips a beat and is thrown off its typical rhythm, you may experience a fluttering feeling. This is known as a heart palpitation.


Your heart rhythm has a direct effect on your blood flow, so low blood pressure caused by atrial fibrillation can lead you to feel lightheaded and dizzy.


Patients with syncope should consider being tested for atrial fibrillation. Similar to lightheadedness, AFib and its associated drop in blood pressure can lead a patient to experience fainting spells.

Blood Clots

Atrial fibrillation may lead to the development of blood clots in some patients. AFib can lead your blood to settle and pool in the atria. As a result, you can get blood clots that can pass through your blood vessels and into your heart, lungs, or brain and cause grave danger.

Chronic Fatigue

Feeling tired all of the time is a sign of AFib. Chronic fatigue that is ruled out from other health conditions can be the result of a lack of oxygenated blood flow.


When the heart is beating irregularly and too fast, you are more likely to sweat. However, if sweating is not apparently aggravated by physical activity or exertion, it may be an underlying symptom of AFib.

Chest Pain

Chest pain is a telltale sign of a heart attack, but many patients don’t realize that chest pain could also be a symptom of atrial fibrillation. Chest pain caused by AFib may also feel like pressure on the chest.


A lack of blood flow that’s caused by AFib often leads to swelling in the extremities. Because the heart is unable to pump blood adequately, patients with AFib often experience swollen feet or hands.

Slurred Speech

Slurred speech is a symptom of poor blood flow—to your brain and other essential organs. When your heart is not pumping blood or oxygen at a health rate, it could have a negative impact on your speech.
