Slow breathing focused through the diaphragm can help with episodes of atrial fibrillation. Take a long, deep breath and hold, before slowly releasing. Vagal maneuvers (techniques that can “shock” the heart back to a steady rhythm) can also help stop episodes. One such maneuver is consuming a glass of ice-cold water. Light exercise has also been shown to successfully halt episodes. If these maneuvers are needed, see your physician to get a treatment plan implemented.
