Atrial fibrillation (AFib) is characterized by an irregular and often rapid heart rate, with episodes lasting longer than 30 seconds. While some individuals may experience nonspecific symptoms like fatigue, dyspnea, dizziness, and diaphoresis, others may remain asymptomatic. AFib can lead to complications such as stroke due to the formation of blood clots in the atria, and its prevalence is expected to increase significantly in the coming decades, affecting millions of Americans over the age of 40 by 2050.
