Causes, symptoms, and diagnosis of atrial fibrillation

Atrial fibrillation is a type of cardiac ailment where the patients experience a rapid heart rate. Such rapid heart rates can lead to heart failure, stroke, and other complications related to your heart. Typically, in atrial fibrillation, the atria beat irregularly and do not work in coordination with the lower heart chambers or ventricles. During atrial fibrillation, patients experience weakness, shortness of breath, and heart palpitations. Causes of atrial fibrillation Atrial fibrillation results in irregular and fast heart rhythm. In the advanced stages of atrial fibrillation, the rate of the heartbeat may increase up to 100 to 175 per minute. A healthy heartbeat goes up to 60 to 100 times a minute. Any damage to the structure of the heart’s chambers or any abnormality is likely to be the prime causes of atrial fibrillation. In certain cases, atrial fibrillation may not be due to any damage or defects of the heart, which is known as lone atrial fibrillation. The possible cause of lone atrial fibrillation is not clear, and it does not usually lead to complications. Here’s a list of the possible causes that lead to a condition of atrial fibrillation: Any metabolic imbalance or an overactive thyroid gland A history of heart surgery Lung diseases Congenital heart disease Heart attacks Coronary artery disease Abnormality in heart valves Abnormality in blood pressure, primarily high blood pressure Sick sinus syndrome caused due to the improper functioning of the heart’s natural pacemaker Stress due to illness, surgery, and pneumonia Viral infections Sleep apnea Symptoms of atrial fibrillation The symptoms of atrial fibrillation highly depend on its causes.
