The study aimed to describe the electrocardiographic and echocardiographic findings in dialysis patients and define the correlation between these findings and dialysis modality. The study found that abnormal electrocardiographic findings were common among pediatric dialysis patients, and echocardiographic assessment showed that systolic dysfunction was also common. Additionally, left ventricular volume in diastole and systole was significantly lower in peritoneal dialysis patients compared to hemodialysis patients, suggesting that peritoneal dialysis patients may experience less pressure and volume loads.
Background: Chronic Kidney disease (CKD) stage V might gradually induce the occurrence of morphological and functional cardiac disturbances; these cardiac disturbances make up supplementary risk factors. Objective: The study aimed to describe electrocardiographic (ECG) and Echocardiographic (Echo) findings in dialysis patients. Also, to define the correlation between Echo findings and dialysis modality.Methods: We studied 27 dialysis patients aged 3 years and one month to 25 years (163 +/- 77 months. Boys accounted for 59.3 % of the patients. The modality of dialysis was peritoneal dialysis (PD) in 33.3 % and he-modialysis (HD) in 51.9 % of cases. Four patients (14.8 %) had undergone both modalities at different times. All patients were taken ECG and Doppler 2D echocardiography (Echo). Assessment of LV systolic function was done according to ejection fraction (EF) and categorized as normal (>= 55 %), mild systolic dysfunction (45-54 %), moderate systolic dysfunction (30-44 %), and severe systolic dysfunction (<30 %) .Results: The most common abnormalities in ECG were left ventricular hypertrophy (70.4 %), prolonged QTC interval (33.3 %), and first-degree atrioventricular block (25.9 %), respectively. Based on the ejection fraction, 40.7 %, 33.3 %, and 26 % of the patients had normal systolic function, mild systolic dysfunction, and moderate systolic dysfunction, respectively. Also, left ventricular (LV) volume in both diastole and systole were signifi-cantly lower in PD compared to HD cases (P = 0.006 and 0.004).Conclusions: We found that abnormal findings in ECG are common among pediatric dialysis patients. Addi-tionally, Echo's assessment noted that systolic dysfunction was common. Significantly lower LV volume in diastole and systole in PD compared to HD cases may suggest that PD patients encounter less pressure and volume loads. These findings can be considered a positive point of PD modality.
