Atrial fibrillation happens when the heart beats at a very fast rate—typically more than
100 beats per minute. Commonly called AFib, atrial fibrillation is the most common form
of arrhythmia, or irregular heartbeat. AFib causes various symptoms and can be very
serious. New technology can treat Afib using faster, more effective methods than in the past. In
this video, San Diego Health host Susan Taylor talks with Doug Gibson, MD, a Scripps
cardiac electrophysiologist and director of cardiac electrophysiology at the Scripps
Prebys Cardiovascular Institute. Learn more: https://www.scripps.org/7942yt
