Inflammatory bowel disease (IBD) (Crohn’s Disease-CD and Ulcerative Colitis-UC) is a chronic autoimmune inflammatory disease. Cardiac involvement and electrophysiologic abnormalities has an important place in terms of morbidity and mortality among extraintestinal involvement. In this study, we investigated p-wave and QTc dispersion which may cause ventricular and supraventricular rhythm disorders if prolonged.


Twenty five IBD patient in remission period and 20 control patient were enrolled to the study. Twelve lead electrocardiogram were evaluated in all patients and p wave dispersion, QT and QTc dispersion was calculated manually.


QTcmax value of IBD patients were higher than control patients (p=0.05). UC patients had higher QTc max value and QTc dispersion than control patients (p=0.042).


UC patients are under risk of ventricular arrhytmias. Follow up with regular ECG in these patients and QTc calculation will be useful in monitoring of IBD patients.
