Causes Of Atrial Fibrillation
Atrial fibrillation can be caused by many different diseases, and some cases do not have any identifiable cause. Some of the most common causes of atrial fibrillation include pulmonary embolism, heart bypass surgery, pneumonia, decongestant medications, diet pills, caffeine consumption, tobacco use, illegal drug use, alcohol abuse, congenital heart disease, heart attack, cardiomyopathy, valvular heart disease, heart failure, and coronary artery disease. All of these conditions cause some type of interference with or damage to the patient's electrical system within their heart. Mechanisms that cause hypoxia, a lack of oxygen, in the coronary arteries can cause permanent damage the body attempts to repair. Damaged heart tissue is repaired with dense and fibrous scar tissue that can cause problems with the electrical system in the atria of the heart, leading to the development of atrial fibrillation.
