What Is Atrial Fibrillation?

 
What Is Atrial Fibrillation?

The atria are the two upper chambers of the heart. They are responsible for receiving blood from the veins. After the atria fill with blood, they contract and move the blood to the ventricles. Atrial fibrillation occurs when the atria beat irregularly. This condition is the most common type of irregular heartbeat.

Who Is At Risk For Developing Atrial Fibrillation?

Anyone can develop atrial fibrillation, but there are some people who are at a greater risk for developing it than others. This condition is more common in older people. High blood pressure, heart disease and sleep apnea are some of the other conditions that can make a person more susceptible to developing atrial fibrillation. Drinking alcohol can also trigger this condition. Additionally, atrial fibrillation has a tendency to run in families.


What Are Some Of The Symptoms Of Atrial Fibrillation?

Heart palpitations, low blood pressure, lightheadedness and shortness of breath are some of the most common symptoms of atrial fibrillation. Confusion is another possible symptom. It is also important to note that some patients who have atrial fibrillation may not show any signs or symptoms.

What Are Some Of The Complications That Can Result If Atrial Fibrillation Is Left Untreated?

Many people experience an occasional bout of atrial fibrillation, and it is usually not a cause for concern. However, if this problem becomes chronic, it can put a person at risk for numerous complications. Atrial fibrillation can trigger a stroke by disrupting blood flow to the brain. Uncontrolled atrial fibrillation can also weaken the heart muscle, which can lead to heart failure.

How Can Atrial Fibrillation Be Treated?

The first thing that a doctor will do is check to see if the patient has an underlying disorder. If the patient has another health condition, that problem will need to be treated first. Patients who do not have an underlying disorder will usually be prescribed an anti-arrhythmic medication. Anti-arrhythmic medications work by helping the heart maintain a normal rhythm. Because people with chronic atrial fibrillation are at an increased for developing blood clots, the doctor may recommend a blood thinner.

Sudden atrial fibrillation can be treated with a procedure called electrical cardioversion. During electrical cardioversion, the doctor will place a paddle on the patient’s chest that will deliver a shock. This shock stops the heart for a brief second. Once the heart starts beating again, it will return to its normal rhythm.

How Can Atrial Fibrillation Be Prevented?

People who have had a history of atrial fibrillation will need to avoid caffeinated beverages and alcohol. They may also need to avoid over-the-counter medications that contain pseudoephedrine. Pseudoephedrine has been shown to trigger atrial fibrillation.
