Data on how the heart is affected in Chronic Urticaria (CU), a common annoying chronic dermatological disease, is quite limited. The electrocardiographic parameters; P wave dispersion (PWD) and QT dispersion (QTD) have been consistently reported to be predictive for cardiac arrhythmias and morbidity. We aimed to detect asymptomatic cardiovascular involvement in terms of predisposition to arrhythmias in chronic urticaria. This cross-sectional study included 128 individuals: 64 with CU and 64 healthy controls. 12-lead surface electrocardiogram and Doppler echocardiography were performed on patients and controls. All of the cardiologic parameters such as P wave, PWD, QTD and corrected QTD (QTDc) parameters were obtained from ECG measurements. Maximum P wave duration and PWD were found to be higher in CU patients than controls (P= 0.035 and P
