Atrial Fibrillation
-
Atrial Fibrillation (AFib) is one of the most common rhythm disorders where the upper chambers of the heart (atria) beat chaotically and in an uncoordinated manner at rates up to 600 bpm, and are not synced with the ventricles.
-
AFib increases the risk of blood clots forming in the atria, potentially leading to stroke.
-
This dysfunctional beating of the atria can lead to clot formation in the atria, potentially leading to stroke. It can also cause palpitations, angina, heart failure, or episodes of blackouts.
-
The risk factors for AFib include:
-
- Incidence increases with age (and 1 in 4 people over 40 are likely to develop AFib)
- Medical history including previous heart attacks, valvular problems, heart surgeries, or cardiomyopathies
- High blood pressure
- Diabetes
- Obesity
- Thyroid issues
- Lung diseases
-
-
Treatment
Treatment of AFib is highly individualized, and depends upon the patient's symptoms, their risk of developing stroke in the future, or any underlying medical and cardiac condition.
-
-
Treatment includes:
-
- Heart rate control: slowing the heart's rhythm
- Rhythm control: restoring normal cardiac rhythm
- Anticoagulation therapy: preventing clot formation
- RF ablation: addressing electrical issues causing AFib
- Lifestyle modifications
