Atrial fibrillation in the older adult. Presentation and management issues.

Atrial fibrillation (AF) is a common cardiac arrhythmia in older adults and the most common cause of embolic stroke. Diagnosis of this illness is a challenge in that the older adult may be asymptomatic and/or may present with such atypical symptoms as a change in function, mood, or cognition. This challenge is demonstrated in three vignettes of older individuals who presented with acute onset AF. Nurses need to evaluate older patients for AF so that prompt treatment can be initiated. This proactive approach can have a major impact on preventing strokes and improving the quality of life in these individuals.
