Atrial Fribrillation Causes
Atrial fibrillation occurs when there is a disturbance in the delivery of electrical signals of the heart, where too many electrical impulses pass through the atrioventricular node (AV node) that acts as an electrical link between the atria and the ventricles. As a result, the heart rate becomes faster (about 100-175 beats per minute) of the normal heartbeat (60-100 beats per minute). This can lead to damage to the heart structure.
Some of the medical conditions suspected to be the cause of atrial fibrillation are:
- Virus infection.
- Congenital heart defects
- Unbalanced metabolism, including overactive thyroid gland.
- Lung disease, high blood pressure, and coronary heart attack.
- Exposure to drugs, alcohol, or tobacco.
- Sleep apnea (sleep apnea) disorders.
- Ever had heart surgery.
- Experiencing sick sinus syndrome, in which the heart’s electrical impulse trigger does not work normally.
- Stress resulting from a disease or surgery.
In addition to the above medical conditions, several other factors that can also make a person susceptible to atrial fibrillation are:
- There is a history of atrial fibrillation disease in the family.
- The habit of consuming alcohol.
