What is a common symptom of atrial fibrillation in the elderly?

Dizziness or lightheadedness is a common symptom of atrial fibrillation, particularly in the elderly population. Atrial fibrillation can lead to irregular and often rapid heart rates, which may result in decreased cardiac output and reduced blood flow to the brain. This can cause the sensation of dizziness or lightheadedness, especially during activities that require increased physical effort or in situations where the heart rate becomes more rapid and less effective in pumping blood.

While palpitations are also a notable symptom and can occur in atrial fibrillation, elderly patients might not report them as frequently due to altered perception of symptoms or pre-existing health conditions. Shortness of breath can also occur, but dizziness and lightheadedness are particularly significant symptoms in the elderly, as they can lead to an increased risk of falls and other complications. Chest pain, although serious, is not as common in atrial fibrillation and may relate more to underlying ischemic heart conditions rather than the arrhythmia itself. Therefore, dizziness or lightheadedness is particularly emphasized as a key symptom when considering the elderly and their unique response to atrial fibrillation.
