Atrial fibrillation, also called AFib, is the most common irregular heartbeat (arrhythmia).

It can interfere with daily life, and can lead to a stroke or heart failure. It is also treatable, thanks to our team’s expertise and range of options.

In healthy hearts, the electrical trigger which contracts the heart is transmitted in a smooth, coordinated manner from the upper chambers to the lower. But in atrial fibrillation, the signal travels chaotically, causing the heart to quiver and either strain to pump or stop.
