Artial Fibrillation
is a medical term used to define abrupt rhythmic movement of the heart
resulting from abnormal electrical impulses in the upper chambers.
Quick Facts
Characterized by arrithmia or irregular heart rhythms
Causes irregular and usually very fast heartbeat
Continuous irregular heartbeat for hours
The electrical impulse originates in the SA node of the right atrium
How heartbeat normally operates?
As the impulse travels through the atrium, it produces a wave of muscle contractions causing the atria to contract
The impulse reaches the atrioventricular (AV) node in the muscle
wall between the two ventricles and pauses there, giving blood from the
atria time to enter the ventricles
The impulse then continues into the ventricles, causing ventricular
contraction that pushes the blood out of the heart, completing a single
heartbeat
AF is most common type of arrhythmia
People with AF may not usually feel any symptoms
Happens rarely or every now and then
People with AF can live normal and active lifestyle
Sometimes ordinary treatment can restore regular heart rhythms
Atrial Fibrillation Causes
Atrial fibrillation may occur without evidence of underlying heart disease
Common in younger people
Overactive thyroid also known as Hyperthyroidism
Use of alcohol
Pulmonary embolism (a blood clot in the lungs)
Pneumonia
Heart valve disease
Developmental abnormalities people are born with
Enlargement of the left ventricle walls
Coronary heart disease resulting from atherosclerosis, deposits of
fatty material inside the arteries that cause blockage or narrowing of
the arteries
Interrupting oxygen delivery to the heart muscle (ischemia)
Hypertension – increased blood pressure
Cardiomyopathy
Sick sinus syndrome referring to improper production of electrical
impulses because of malfunction of the SA node in the atrium of the
heart
Pericarditis – inflammation of the sac surrounding the heart
Myocarditis – inflammation of the heart muscle
Increasing age
Cardiothoracic surgery or procedures
Atrial Fibrillation Symptoms
Palpitations feelings that your heart is skipping a beat
Fluttering, or heart beating too hard or fast
Shortness of breath
Weakness or problems exercising
Chest pain
Dizziness or fainting
Fatigue
Consta nt tiredness
Confusion
