ABSTRACT
Atrial fibrillation (AF) is the most common arrhythmia. Its prevalence is 5% in patients of 65 years of age or older, and the prevalence increases with advancing age. Data from the Framingham study have shown that AF is associated with a 1.51.9-fold higher risk of death, presumably as a result of thromboembolic stroke. AF is associated with several conditions that should be sought when taking the history (Table 11.7).
