Atrial fibrillation (AFib) is a heart rhythm abnormality caused by a problem with your heart's electrical system. Normally, your heart's electricity flows from the top chambers (atria) to the bottom chambers (ventricles), causing a normal contraction. In atrial fibrillation, the electrical flow ...
Age.The older you are, the greater your risk of developing atrial fibrillation. Heart disease.Anyone with heart disease — such as heart valve problems, congenital heart disease, congestive heart failure, coronary artery disease, or a history of heart attack or heart surgery — has an increased...
Atrial fibrillation ( AF or Afib ) is a supraventricular tachyarrhythmia and the most common kind of arrhythmia. It is caused by rapid, uncontrolled atrial contractions and uncoordinated ventricular responses. There are many conditions that can cause AF , usually damage to the heart (e.g., ...
a faster heartbeat. Atrial fibrillation decreases the efficiency of the pumping action of the heart. It also increases the risk of formation of blood clots inside the heart. These blood clots can break off and go to other parts of the body, including the brain where they can cause a ...
As disease in the AV node advances, these people can even develop an excessively slow heart rate and require a permanent pacemaker to increase the rate of ventricular contractions. Diagnosis of atrial fibrillation Atrial fibrillation can be chronic and sustained, or brief and intermittent (paroxysmal...

Paroxysmal atrial fibrillationmay occur in a healthy heart in the following situations: Acute alcoholism; Coffee and tobacco abuse; Stress. In a diseased heart,paroxysmal atrial fibrillationoccurs in the following situations: Myocardial infarction; ...
Trials are underway at a London hospital to treat a heart rhythm disorder by removing some of the heart’s nerve endings. The Royal Brompton Hospital is using the experimental treatment forAtrial Fibrillation(AF), an irregular and often abnormally fast heart rate, which can affect people with ca...
Atrial fibrillation caused by an excess of thyroid hormones (hyperthyroidism) can be treated with medication or surgery to address the underlying condition. When rheumatic heart disease is the cause, the condition may be treated with surgery to repair or replace heart valves damaged by the disease....
