Rhythm restoration important for some with atrial fibrillation
Although controlling the heart's rate is a good first step for treating atrial fibrillation, some people benefit from restoring a normal rhythm.
What to do when atrial fibrillation sets the upper chambers of the heart aquiver has vexed doctors for years. They traditionally focused on restoring the normal, steady rhythm known as sinus rhythm. That's a logical approach — after all, it's the tempo of a healthy heart. Another approach involves allowing the atria to continue contracting erratically and instead controlling the beat of the ventricles, the heart's lower chambers.
