Brief Summary

Atrial fibrillation (AF) is a condition in which the upper chambers of the heart, the atria, undergo an irregular beating rhythm. Despite the fact that AF is the most common type of sustained cardiac rhythm disturbance the investigators still do not understand it entirely and its current therapies are only marginally effective. The overall goal of our project is to determine the organization and mechanisms of electrical activation patterns during AF in humans.
