Vorhofflimmern
A patient with atrial fibrillation may experience symptoms of fatigue, dizziness or lightheadedness, heart palpitations, chest pain, and shortness of breath. The heart does not effectively pump blood into the pulmonary or systemic vasculature, and causes the blood to remain within the chambers of the heart. The collection of blood within the heart due to atrial fibrillation can cause and increase the risk of development of a thrombus (blood clot). The thrombus can also develop into an embolus (mobile blood clot) and travel into the systemic circulation. Atrial fibrillation is associated with an increase in risk of having a stroke especially if the embolus travels to the brain.
