Atrial fibrillation is an irregular heartbeat
that increases the risk of stroke and heart disease. Atrial fibrillation (also referred to as AFib or AF) is the most common type of abnormal heart rhythm. People who have AF are at increased risk for stroke. Control your heart rate to restore a normal heart rhythm. Atrial fibrillation is a disorder that causes an irregular heart rate, or arrhythmia.
Normal sinus rhythm is the normal rhythm of the heart in which an electrical impulse originates in the sinus node, which then stimulates the atria (upper chambers of the heart) to contract and empty blood into the ventricles (lower chambers of the heart).
Atrial fibrillation is an irregular and often rapid heart rate that occurs when the two upper chambers of your heart (atria) experience chaotic electrical signals. It represents the endocardial shell of the right atrium and is used as the template during left atrial ablation procedures.
An EKG shows how fast your heart is beating and its rhythm (steady or irregular). These blood clots may move into the ventricles (lower chambers of the heart) and get pumped into the lungs or the general blood circulation. Atrial size is an important factor in determining how a patient responds to treatment for the disease.
A normal heart rate, when you are resting, should be between 60 and 100 beats a minute. During each heart beat, the two upper chambers of the heart (atria) contract, followed by the two lower chambers (ventricles). Radiofrequency catheter ablation is a treatment that uses high frequency radio waves to destroy the tissue source of atrial fibrillation.
This series for patients and caregivers provides information about the care and management of atrial fibrillation. In addition, the 16% prevalence of atrial fibrillation that we observed in the intervention group is likely to be a conservative estimate for several reasons.
Before the development of catheter ablation, open heart surgery was done to interrupt conducting pathways in both atria. Medicines used to control the heart rhythm include amiodarone, sotalol, flecainide, propafenone, dofetilide, and ibutilide. During atrial fibrillation, erratic electrical impulses start in the upper chambers of the heart (atria), which affect the normal electrical pathway through the rest of the heart.
8. Rosenthal L. Atrial Fibrillation. Some people with atrial fibrillation have no symptoms and it is only discovered during routine tests or investigations for another condition. Restoring and maintaining a normal heart rhythm is a treatment approach recommended for people who aren't doing well with rate control treatment.
Afib is a significant risk factor for stroke. 18 Otherwise the decision of rate control versus rhythm control using drugs is made. Nonvalvular atrial fibrillation, which occurs in the absence of rheumatic valve disease, a mechanical or bioprosthetic valve, or mitral valve abnormalities, is the most common form of atrial fibrillation.

If your heart rate is brought down to normal, your heart becomes efficient again and your symptoms usually improve. ECG tracing shows a variable heart rate, irregularly-irregular rhythm, usually absent P-waves and non-distinct P-R interval, and a normal QRS interval of less than 0.12 seconds.
