Atrial fibrillation remains one of the most common and complex cardiac arrhythmias, with rapidly evolving evidence informing best practices for diagnosis and management. In this Grand Rounds, Gregory Marcus will review key updates from the latest AFib management guidelines and discuss practical approaches to evaluating patients with a new diagnosis. He will also highlight the growing role of lifestyle and modifiable risk factors in AFib prevention and treatment, as well as how these considerations can be integrated into clinical care.
