(PHYSorg.com Medicine & Health)

People who experience migraine with visual aura may have an increased risk of an irregular heartbeat called atrial fibrillation, according to a study published in the November 14, 2018, online issue of Neurology, the medical journal of the American Academy of Neurology. Migraine with visual aura is when disturbances in vision occur right before head pain begins. Those disturbances may include seeing wavy lines or flashes of light, or having blurry vision or blind spots.
