Can dehydration cause atrial fib

Yes, dehydration can contribute to atrial fibrillation (AFib) by causing electrolyte imbalances and increased stress on the heart. When the body is dehydrated, it can lead to a reduction in blood volume, which may trigger abnormal heart rhythms. Additionally, low levels of potassium and magnesium, often seen in dehydration, can further increase the risk of AFib. Maintaining proper hydration is important for overall heart health.
