Introduction: Types of Atrial Fibrillation; B. Permanent:
C. Persistent: ; D. Paroxysmal:
Atrial fibrillation (AF) is a type of arrhythmia, or irregular heartbeat, that originates in the atria, the upper chambers of the heart. In AF, the atria quiver instead of contracting normally, which can lead to blood pooling and clot formation. Clots can travel to the brain and cause a stroke.
There are three main types of AF: permanent, persistent, and paroxysmal. Permanent AF is a type of AF that does not go away. Persistent AF is a type of AF that goes away but comes back again. Paroxysmal AF is a type of AF that comes and goes.
Symptoms of Atrial Fibrillation
Atrial fibrillation is a condition in which the heart’s rhythm is irregular. This can cause the heart to pump less blood out to the body. Symptoms of atrial fibrillation may include:
-An irregular heartbeat, which you may be able to feel
-Chest pain
-Shortness of breath
-Dizziness
-Fainting
-Weakness
-Heart palpitations, which is a feeling that your heart is beating too fast or too hard
A. Long-Standing:
This means that the issue has been around for a long time and has not been resolved.
B. Important: This means that the issue is important to people and should be resolved.
C. Resolved: This means that the issue has been resolved and people are happy with the outcome.
C. Paroxysmal:
a sudden attack or recurrence of a disease, especially a seizure
A seizure is a sudden, uncontrolled electrical storm in the brain. Seizures can cause a person to shake, lose consciousness, or have a change in behavior.
D. Persistent:
Persistent means that the condition continues to exist even after the cause has been removed. For example, if a person has a persistent headache, the headache will continue to exist even after the cause (such as a head injury) has been removed.
E. Nonvalvular:
Nonvalvular is a term used to describe heart valves that are not affected by rheumatic fever. Rheumatic fever is a serious, potentially life-threatening disease that can damage the heart valves.
Functioning of Normal Heart and its Electrical System Working
When the heart muscle contracts, it squeezes blood out of the heart and into the body. The electrical system of the heart controls the timing and strength of the heart muscle contractions. The electrical system of the heart begins with special cells in the heart that generate an electrical signal. This signal spreads through the heart, causing the heart muscle to contract in a coordinated way.
Reason behind Atrial Fibrillation
There is no one definitive answer to this question. Some of the possible causes of atrial fibrillation include:
Heart disease
High blood pressure
Atherosclerosis
Heart attack
Heart failure
Smoking
Alcohol abuse
Diabetes
Stress
Sleep apnea
Certain medications
Abnormal heart rhythms
The cause of atrial fibrillation in many cases is not known.
