Atrial Fibrillation: Causes and Risks
Atrial fibrillation, also known as AFib, is a prevalent form of tachycardia characterized by irregular and chaotic electrical impulses in the atria. This condition leads to rapid, weak, and uncoordinated contractions of the atria. While most people with atrial fibrillation have heart structural abnormalities associated with underlying conditions like high blood pressure and heart disease, other factors such as hyperthyroidism, heart valve disorders, and excessive alcohol consumption can also contribute to the development of this type of tachycardia. It’s important to note that atrial fibrillation can increase the risk of blood clot formation within the heart, which in turn raises the likelihood of experiencing a stroke.
Atrial Flutter: Causes, Symptoms, and Treatment
Atrial flutter is a cardiac condition characterized by a rapid and regular beating of the atria, leading to weak atrial contractions. This condition is primarily caused by irregular circuitry within the atria. It is worth noting that individuals with atrial flutter often experience atrial fibrillation at other intervals. While some cases of atrial flutter may resolve on their own, others require medical intervention to effectively manage the condition.
