Atrial fibrillation AF or A-fib is an abnormal heart rhythm characterized by rapid and irregular beating of the atria. A systematic review and meta-analysis". This is not a sign of weakness. Retrieved 28 May Philadelphia: Saunders. Since most cases of AF are secondary to other medical problems, the presence of chest pain or anginasigns and symptoms of hyperthyroidism an overactive thyroid gland such as weight loss and diarrheaand symptoms suggestive of lung disease can indicate an underlying cause. This dangerous situation is prevented by the AV node since its limited conduction velocity reduces the rate at which impulses reach the ventricles during AF. National Collaborating Centre for Chronic Conditions. Many of the symptoms associated with uncontrolled atrial fibrillation are a manifestation of congestive heart failure due to the reduced cardiac output. Journal of the American Geriatrics Society.
Atrial Fibrillation (AFib) Heart Rhythm Society
Usually the atria and ventricles work together so the heart pumps blood in steady rhythm. But in AFib, they don't. The irregular beats can cause a fast, fluttering. When it's not, you could have an irregular heartbeat called AFib.
ECG Rhythms Can atrial fibrillation (AF) be regular
When everything is working smoothly, you have a normal sinus rhythm and your heart beats between 60 and times per minute. Atrial fibrillation, also called AF or AFib, is the most common type of irregular.

Atrial Fibrillation (A Fib) is one of the most common abnormal heart rhythms, ( the ventricles) and results in a regular rhythmic contraction of the chambers.

Methodist Debakey Cardiovasc J. The most accurate clinical prediction rules are: . Also, people with a higher risk of AF, e.

Neither rate nor rhythm control is superior in people with heart failure when they are compared in various clinical trials. Retrieved 2 October Popular Courses.
This regularly irregular rhythm cannot be atrial fibrillation.
Indeed, a repeat ECG ( figure 1C) confirms the presence of P waves. This is, in fact, a marked sinus. Atrial flutter and atrial fibrillation (AFib) are two types of atrial tachycardia.
or not a normal rhythm) where the atria of the heart beat too quickly in a fast, usually regular, rhythm.
Picture of the heart's abnormal electrical conduction in AFib.
QRS complexes should be narrow, signifying that they are initiated by normal conduction of atrial electrical activity through the intraventricular conduction system. Measures should be taken to control hypertension preoperatively to reduce the risk of AF. A Holter monitor is a wearable ambulatory heart monitor that continuously monitors the heart rate and heart rhythm for a short duration, typically 24 hours.

A history of stroke or TIA, as well as high blood pressurediabetesheart failureor rheumatic fever may indicate whether someone with AF is at a higher risk of complications. Anticoagulation is recommended in most people other than those at low risk of stroke  or those at high risk of bleeding.
