stroke is a risk factor that nurses teach about.
atrial fibrillation is mostly brought on by chaotic signals that cause the atria, the two top chambers of your heart, to contract quickly and out of time. Because of how swiftly they contract, the heart's walls fibrillate. atrial fibrillation may result from electrical system damage to your heart.
Blood doesn't flow as well as it should from the two atria to the lower chambers of the heart when a person has atrial fibrillation because the two atria's usual beating is irregular (the two ventricles). atrial fibrillation may occur in isolated incidents or it may be a chronic illness.
