ECG Changes in Patients with Chronic Kidney Disease: A Cross-Sectional Observational Study

Abstract

Chronic kidney disease (CKD) is frequently associated with cardiovascular abnormalities, including left ventricular hypertrophy, conduction disturbances, and arrhythmias. This study evaluated electrocardiographic (ECG) changes among 72 patients with CKD using a descriptive cross-sectional design. CKD was confirmed through clinical, laboratory, and imaging criteria, and data were analyzed using SPSS 25.0. Among the patients, 68.1% were male, with a mean age of 52.32 ± 17.15 years. Hypertension was the leading etiology (37.5%). ECG abnormalities were observed in 55.5% of patients, with left ventricular hypertrophy (LVH) being the most common abnormality (33.3%). Anemia and electrolyte disturbances were also prevalent. The findings indicate that LVH was the most frequent ECG abnormality among CKD patients, with hypertension and diabetes being common etiologies, highlighting the importance of early cardiovascular assessment and intervention.
