How does stress relate to atrial fibrillation?

Stress is recognized as a common trigger for atrial fibrillation (AF), which is irregular and often rapid heart rhythm originating in the atria. In the context of AF, stress can have physiological effects such as the release of stress hormones like adrenaline. These hormones can increase heart rate and destabilize the electrical activity of the heart, making it more susceptible to developing arrhythmias like AF.

Research and clinical observations consistently show that episodes of significant emotional or physical stress are associated with an increased incidence of atrial fibrillation. Factors tied to stress, including anxiety and high blood pressure, can exacerbate underlying predispositions to AF, leading to its manifestation.

Understanding this connection helps clinicians in both the diagnosis and management of AF, as addressing stress through mental health support or lifestyle modifications can be an important part of treatment strategies for individuals prone to this arrhythmia.
