Atrial electromechanical delay analysed by tissue Doppler echocardiography is prolonged in patients with generalised anxiety disorders

Abstract

Background: It has been shown that psychological status is associated with the likelihood of atrial fibrillation (AF). Prolongation of the duration of atrial electromechanical delay (AEMD) is known to be a precursor for AF development.

Aim: Therefore, we aimed to evaluate AEMD in patients with anxiety disorder.

Methods: In this prospective study, a total of 82 anxiety disorder and 80 healthy subjects were enrolled. Symptoms of anxiety were evaluated by using the Hamilton Anxiety Rating Scale (HAM-A). P-wave dispersion (PWD) was measured on a 12-lead electrocardiogram. Both intra- and inter-AEMD were measured with tissue Doppler imaging.

Results: Basal characteristics were similar between the two groups. PWD, inter- and right intra-AEMD were significantly prolonged in patients with anxiety disorders, compared to the control group (p < 0.05). In the correlation analysis, HAM-A was significantly and moderately correlated with right intra- and inter-AEMD, and PWD.

Conclusions: Patients suffering from anxiety disorders are characterised by prolonged AEMD, which can provide significant contributions to evaluate the risk for AF development in this group.
