Abstract
dialysis ECG was significantly correlated with the ultrafiltration volume (b =0.282, 0.041). Conclusion: Increased dispertion of QTc and P wave may indicate abnormally increased inhomogeneity of electrical activity of myocardium and atrium which could precede sustained arrhythmia. In patients with dialysis, older ages over 40 years and presence of ischemic heart disease may lead increased dispertion of QTc and also probability of ventricular arrhythmia. Additionally usage of Ca antagonists was positively and beta blockers was negatively correlated with QTcd. Positive correlation of Increased P wave dispertion to ultrafiltration volume support the volume overload may increase the tendency to atrial arrhythmia via increase P wave dispertion.
