In atrial fibrillation, also called Afib, electrical signals in your heart’s upper chambers (atria) cause your atria to beat quickly and chaotically, which causes an irregular fast heart rhythm. Afib is a common type of heart rhythm disorder (arrhythmia). A heart in Afib doesn’t beat efficiently. It may not be able to pump enough blood out to your body with each heartbeat.
Some people with Afib have no symptoms and are unaware of their condition until it’s discovered during a physical examination. Those who do have Afib symptoms may experience:
You may be a candidate for a procedure or “intervention,” if medications are not effective in treating Afib. Our team includes a specially-trained cardiologist called an electrophysiologist. This cardiologist is highly trained in the area of “mapping” the irregular electrical impulses in the heart. The electrophysiologist then uses these maps to form a plan to eliminate those electrical paths with the intent of reaching a regular heart beat. Mayo Clinic Health System is the only cardiac program in this region with an electrophysiologist as part of the medical team.
