Increased frequency of atrial fibrillation (AF) has been demonstrated in psoriasis cases. Prolongation of the duration of atrial electromechanical delay (AEMD) is a well‐known characteristic of the atrium, which is vulnerable to AF. In the current study, our aims are to investigate AEMD durations and mechanical functions of the left atrium (LA) in patients with psoriasis.

A total of 90 patients, 45 with psoriasis vulgaris and 45 as the control group, were included in the study. Atrial electromechanical coupling (PA) and intra‐ and inter‐atrial electromechanical delay (IA‐AEMD) were measured with tissue Doppler echocardiography. P‐wave dispersion (PWD) was calculated from the 12‐lead electrocardiogram. The severity of the disease was evaluated by the Psoriasis Area and Severity Index.

The durations of PA lateral and PA septal were significantly high in the psoriasis group when …
