At the end of the first decade of the 21st century, approximately 6 million individuals in the United States have AFib.  This prevalence, however, will represent a growing healthcare burden, with recent estimates that it may increase to as many as 12 to 15 million Americans with AFib by 2050 [1]  [2] [3] In part this increase is a simple result of the fact that AFib is a disease where prevalence increases with age, and the older population segment is one of the more rapidly growing subsets of United States.
