New techniques for treating atrial fibrillation
New devices and treatments can help prevent irregular atrial heart rhythms and related risks.
When your heart is pumping well, the four chambers contract and relax in a rhythmic, coordinated manner. However, a malfunction in the heart's internal electrical system can disrupt the normal beating sequence. As a result, the two upper chambers, the atria, can go into a fast, irregular quiver known as atrial fibrillation, or "afib."
