Background: The polycystic ovary syndrome (PCOS) is associated with various cardiac manifestations including cardiac arrhythmias. P-wave dispersion (Pdis) is an appealing marker for predicting the risk of developing atrial arrhythmias. The purpose of this study was to evaluate P-wave durations and Pdis in patients with PCOS. Methods: Forty adult patients with PCOS and 46 age- and sex-matched healthy individuals were included in this study. P-wave maximum duration (Pmax) and P-wave minimum duration (Pmin) were calculated on the 12-lead electrocardiogram, and the difference between the Pmax and the Pmin was defined as Pdis. All individuals also underwent transthoracic echocardiographic evaluation. Results: Pmax and Pdis were significantly higher in patients with PCOS compared with controls (p = 0.007, p < 0.001, respectively). There was no difference in Pmin duration between both the groups (p = 0.2). Waist-to-hip ratio, insulin and homeostasis model assessment of insulin resistance (HOMA-IR) were higher in the PCOS group. Early mitral inflow deceleration time (DT) (p < 0.001) and isovolumetric relaxation time (p = 0.003) were longer in PCOS group. Waist-to-hip ratio, DT, E/A ratio and diastolic blood pressure correlated with Pdis. Conclusions: Patients with PCOS have prolonged Pmax and Pdis. The increase in those parameters may be an indicator for identification of patients at increased risk of atrial fibrillation. © 2013 Informa UK Ltd.
