2. Introduction
What is atrial fibrillation?
- Heart disease.
- Heart condition that causes heart to function in irregular
rhythm.
- Increases risk of heart failure, stroke and even death.
3. Human Heart
- Consists of four chambers
1. Two upper chambers……ATRIA
2. Two lower chambers…….VENTRICLES
- Under normal conditions these four chambers work together to pump
blood throughout the body.
- How does it function

5. Possible Risk Factors
Age
Family History
Smoking
High Blood Pressure (Hypertension)
Obesity
Diabetes
Coronary Artery Disease
6. Types of Atrial Fibrillation
1.Paroxysmal Afib
In this case periods of Afib may come and these episodes are momentary
or last for days but generally go away on their own.
2.Persistent Afib
Afib not go away on its own and doctors may needs to provide medicine
to bring the heart back to normal rhythm.
3.Permanent Afib
Heart not able to return its normal rhythm at all
9. Effects of Afib on Heart
Remodelling
Because of Afib, your heart has to work
much harder and heart tissues can be
damaged.
10. Stroke Risk
During Afib, blood can collect in your heart
and cause a clot to form
Afib patients are more likely to get stroke than
normal person
11. Control of Afib
1. Rate Control
2. Rhythm Control
3. Combination of both
4. Cardioversion
5. Radio frequency ablation
6. Surgical ablation
7. Atrial pacemaker
12. 1. Rate Control
medicines given to control heart rate
but heart continues to beat irregularly and out of rhythm
2. Rhythm control
medicines are used to control the rhythm of heart
but heart beats at faster rate
So it is always preferable to go for the combination of
these two control methods
13. 4. Cardioversion
electrical current used to restore normal heart rhythm
5. Radio frequency ablation
procedure that stops the heart from setting of faulty electrical
signals that cause chaotic heart beat of Afib
14. 5. Surgical ablation
surgical procedure to destroy the cells causing abnormal
heart rhythm and may be used when other treatments not work
6. Atrial Pacemaker
a small battery powered device implanted under the skin to
generate electrical signals to regulate heart beat
