Atrial fibrillation During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness. Episodes of atrial fibrillation can come and go, or you may develop atrial fibrillation that doesn't go away and may require treatment.

Heart, Vascular and Thoracic Care Mild aortic enlargement may not cause any noticeable symptoms at first. An enlarged aorta, however, may allow blood to leak back into the heart, due to aortic valve insufficiency. This can cause shortness of breath and a pounding heartbeat. More severe aortic enlargement can further weaken the aortic wall, causing the aneurysm to enlarge or dissect.

Symptoms of Atrial Fibrillation Low Oxygen and Symptoms of Atrial Fibrillation. Atrial fibrillation can decrease the amount of blood your heart pumps with each beat by as much as 20 to 30 percent. As a result, other symptoms will occur when your body isn't getting enough oxygen and nutrients. These include:

Left Bundle Branch Block You are more likely to have symptoms if you have other problems in addition to your left bundle branch block. In people with heart failure, left bundle branch block can sometimes make those symptoms worse. In these people, left bundle branch block can worsen shortness of breath and fatigue. If both your right and left bundles become blocked, you could have a complete heart block. When this happens, the impulses from the top chambers of the heart do not activate the lower chambers of the heart.

What are the Causes of Atrial Fibrillation? It is extremely rare for atrial fibrillation to develop in younger patients, unless they have an underlying heart condition. Experts say there are many cases in which the cause of the atrial fibrillation was never found. Here is a list of the most common causes: 1  Hypertension-high blood pressure. 2  Coronary artery disease-also known as coronary heart disease. 3  Plaque builds up inside the coronary arteries. 4  These arteries supply the heart muscle with blood that is rich in oxygen.

- In asthma, shortness of breath is usually caused by the narrowing of the airways. The airways become narrow for one or both reasons: The muscles that surround the airways tighten up (“bronchospasm”).

Atrial Fibrillation What Are the Signs and Symptoms of Atrial Fibrillation? Atrial fibrillation (AF) usually causes the heart's lower chambers, the ventricles, to contract faster than normal. When this happens, the ventricles can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body. This can lead to signs and symptoms, such as: 1  Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast) 2  Shortness of breath. 3  Weakness or problems exercising.  Chest 1  pain. Dizziness or fainting.  Fatigue 1  (tiredness) Confusion.

Atrial Fibrillation - Cause Problems that affect the heart's structure. Atrial fibrillation is often caused by a health problem that directly affects the heart, including: 1  High blood pressure.2  Coronary artery disease. 3  Heart attack. 4  Heart failure. 5  Heart valve disease. 6  Cardiomyopathy.trial fibrillation is a problem with the heart's electrical system. When something goes wrong with this system, it's usually because of other health problems that are causing wear and tear on the heart or making it hard for the heart to do its job.

- What causes atrial fibrillation? Certainly genetics plays a role but the big three causes of A-fib are age, high blood pressure, and obesity. Most cases of A-fib, just like other forms of heart disease, are completely preventable. Indeed, studies have shown that 80% of heart disease is totally preventable [3] .

Overview The cause of ventricular fibrillation isn't always known. The most common cause is a problem in the electrical impulses traveling through your heart after a first heart attack or problems resulting from a scar in your heart's muscle tissue from a previous heart attack. Some cases of ventricular fibrillation begin as a rapid heartbeat called ventricular tachycardia (VT).

Overview If a heart attack occurs, often as a result of severe coronary artery disease, it can trigger ventricular fibrillation and sudden cardiac arrest. In addition, a heart attack can leave behind areas of scar tissue. Electrical short circuits around the scar tissue can lead to abnormalities in your heart rhythm.

- Atrial fibrillation, or A-Fib, is a common arrhythmia in which the heart's upper chambers (the atria) quiver rather than contract (squeeze) normally, sometimes as many as 600 times per minute. This causes the heart's lower chambers (the ventricles) to contract out of rhythm and faster than normal. Without treatment, A-Fib can lead to other serious heart problems, like enlargement of the heart (called cardiomyopathy) and heart failure (when the heart cannot fill or pump enough blood to meet the body's needs).

Causes Most cases of shortness of breath are due to heart or lung conditions. Your heart and lungs are involved in transporting oxygen to your tissues and removing carbon dioxide, and problems with either of these processes affect your breathing. Shortness of breath that comes on suddenly (called acute) has a limited number of causes, including: Asthma (bronchospasm) Carbon monoxide poisoning. Cardiac tamponade (excess fluid around the heart) Hiatal hernia. Heart failure. Low blood pressure (hypotension) Pulmonary embolism (blood clot in an artery in the lung)

WHAT IS ATRIAL FIBRILLATION? About Atrial Fibrillation. Atrial fibrillation, known as AF or Afib, is an irregular and often very fast heart rate. This may cause symptoms like heart palpitations, fatigue, and shortness of breath. Treating atrial fibrillation is important because it may cause a stroke and negatively impact your quality of life.

Heart Disease and Sudden Cardiac Death Most sudden cardiac deaths are caused by abnormal heart rhythms called arrhythmias. The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers). When this occurs, the heart is unable to pump blood and death will occur within minutes, if left untreated.

Atrial Fibrillation (AFib) Symptoms, ECG, and Treatment Medications 1 AFib reduces the ability of the atria to pump blood into the ventricles, and usually causes the heart to beat too rapidly. 2  One-half million new cases of atrial fibrillation are diagnosed every year in the U.S., and billions of dollars are spent annually on its diagnosis and treatment.

How does digoxin treat atrial fibrillation? Atrial fibrillation (AF or A-Fib) is a heart rhythm disturbance, that causes an irregular and often very rapid, fluttering heart rate (heart palpitations). A-Fib occurs when the upper chambers of the heart (the atria) beat chaotically and out of sync with the lower chambers (the ventricles).

Heart Attack (Myocardial Infarction) Permanent brain damage and death can occur unless the flow of blood to the brain is restored within five minutes. Heart attack is the most common cause of ventricular fibrillation. Less common causes of cardiac arrest include respiratory arrest (loss of breathing function), choking, trauma, electrocution, and drowning. Medically Reviewed by a Doctor on 9/8/2014.
