What Causes an Arrhythmia? An arrhythmia can occur if the electrical signals that control the heartbeat are delayed or blocked. This can happen if the special nerve cells that produce electrical signals don't work properly. It also can happen if the electrical signals don't travel normally through the heart.
The most common cause of stroke from an arrhythmia is atrial fibrillation. Atrial fibrillation can cause blood clots to form in the atria (top chamber of the heart) where they can be pumped out of the heart, to the brain, blocking a blood vessel and causing a stroke. Treatment for atrial fibrillation focuses in part on reducing the risk of stroke.
