The heart has two chambers.
The heart has four chambers: two atria and two ventricles. After the body has received the oxygen delivered in the blood, the now oxygen-poor blood travels to the right atrium and is then pumped into the right ventricle. The right ventricle pumps the oxygen-poor blood into the lungs where the blood picks up more oxygen. The left atrium receives this oxygen-rich blood from the lungs and pumps it into the left ventricle. The left ventricle pumps the oxygen-rich blood to the body.
Atrial fibrillation (AFib) is a common type of irregular heartbeat (arrhythmia).
AFib is a common type of irregular heartbeat. There are two types of AFib: one caused by a heart valve problem, and one that is not. The majority of AFib is not caused by a heart valve problem and was estimated to affect approximately 6.4 million Americans in 2014.
On average, the healthy heart beats approximately 60 to 100 beats per minute.
A healthy human heart rate is 60 to 100 beats per minute. With AFib, it may beat anywhere from 100 to 175 times per minute!
AFib not caused by a heart valve problem can cause blood clots, which may lead to stroke.
With AFib, the top chambers of the heart (the atria) do no contract properly to push blood through the heart. As a result, some blood remains in the atria, which can pool, and clots may form. These clots can travel to the brain, blocking or limiting blood flow, and may result in a stroke.
Three possible ways to tell if someone is having a stroke are by sudden changes in the way their face and arm work and how they speak.
Other symptoms that occur suddenly include confusion, trouble seeing with one or both eyes, leg weakness, trouble walking, dizziness, loss of balance or coordination, and severe headache.
Strokes caused by AFib can be less severe and are less likely to be fatal than strokes not related to AFib.
Strokes caused by AFib can be more severe and more likely to be fatal compared to strokes not associated with AFib.
People with AFib not caused by a heart valve problem are less likely to suffer from a stroke.
People with AFib not caused by a heart valve problem are at a five times greater risk of stroke.
AFib is one of the most common risk factors for stroke.
A history of congestive heart failure, hypertension, age greater than or equal to 75, diabetes, and prior history of stroke or "mini-stroke" are factors that can further increase risk of stroke in patients with AFib not caused by a heart valve problem.
AFib symptoms may include fluttering or "thumping" in the chest, dizziness, and shortness of breath.
Also, AFib can be diagnosed by reviewing medical and family histories, completing a physical exam, and conducting diagnostic tests and procedures. If someone has AFib not caused by a heart valve problem, it is important for them to work with their doctor to discuss treatment options that can help reduce the risk of stroke.
People with AFib not caused by a heart valve problem are not at an increased risk of stroke if they have no symptoms.
People with AFib not caused by a heart valve problem are at an increased risk of stroke, even if they have no symptoms. If someone has AFib not caused by a heart valve problem, it is important for them to work with their doctor to discuss treatment options that can help reduce the risk of stroke.
