Key result
Patients with generalized anxiety disorder had significantly increased P wave dispersion (50.0 vs 23.4 ms) and QT dispersion (50.5 vs 28.3 ms) compared to healthy controls.

Generalized anxiety disorder is associated with significantly increased P wave and QT dispersion, suggesting a potential non-invasive marker for increased risk of atrial fibrillation and ventricular arrhythmias in this population.
The aim of this study is to investigate P wave dispersion (Pd) and QT dispersion (QTd), non-invasive predictors of atrial fi brillation and ventricular arrhythmia or sudden cardiac death, respectively, in patients with generalized anxiety disorder (GAD).

Ünsal et al. (2013) conducted a case-control in Generalized Anxiety Disorder (n=69). Generalized Anxiety Disorder vs. Healthy controls was evaluated on P wave dispersion (Pd) (p=<0.001). Patients with generalized anxiety disorder had significantly increased P wave dispersion (50.0 vs 23.4 ms) and QT dispersion (50.5 vs 28.3 ms) compared to healthy controls.
