Heart Health Treatments If you have an irregular heartbeat, find out whether you should remain in atrial fibrillation or have sinus rhythm restored. An irregular heartbeat or atrial fibrillation occurs when the upper chambers of the heart quiver instead of pumping blood properly. Once diagnosed, one of the first things to ask is whether to remain in atrial fibrillation or to have sinus rhythm restored. There is no right or wrong answer, but it’s important for patients to talk to their doctors and learn the risks behind either option. RELATED PROGRAMS
