Background: Cardiovascular disease is the leading cause of mortality among patients on dialysis. When considering all causes of death, about 30% are classified as cardiac arrest, death of unknown cause or cardiac arrhythmia. The increasing time of ventricular depolarization and repolarization, measured non-invasively by measuring the QT interval on the electrocardiogram at rest, has emerged as a predictor of complex ventricular arrhythmias, a major cause of sudden cardiac death. Objective: To evaluate electrocardiographic abnormalities in patients with Chronic kidney disease on Maintenance Hemodialysis. Method: This cross sectional observational study design was carried out through the present investigation from Jun 2nd January/2019 to2/July/2019 in order to achieve the objectives of the present study . A nonprobability (purposive)sample of 120 patient which including (86) males and (34) females. Who were attending Hemodialysis Unit in AL- Hussein Teaching Hospital. The results according to the special criteria. Results: Total number of patients included in the study was 124 Mean age of all patients was 49.9±13.8 years, 106 (84.8%) had hypertension, 84 (70%) had diabetes mellitus, and 35 (29.9%) had known cardiovascular disease. Mean serum creatinine was 7.±3.4mg/dl, mean eGFR was 10.6±9.2 ml/min/1.73m2. Overall 78.4% of all CKD patients have one or more ECG abnormality. Left ventricular hypertrophy (40%), Q waves (27.2%), ST segment elevation or depression (23.4%), prolonged QRS duration (19.2%), tachycardia (17.6%) and left and right atrial enlargement (17.6%) were the most common abnormalities. Conclusion: ECG abnormalities are common in hospitalized CKD patients in local population. All hospitalized CKD patients should undergo ECG to screen for cardiovascular disease.
