RELATIONSHIP BETWEEN ELECTROCARDIOGRAPHY AND ELECTROLYTES BEFORE AND AFTER DIALYSIS IN HEMODIALYSIS PATIENTS

Background: Cardiovascular events are the most important cause of mortality in hemodialysis patients. Rapid volume changes and electrolyte shifts during dialysis lead to arrhythmias. Objective: We aimed to determine whether there is a relationship between electrocardiographic (ECG) wave and interval changes and electrolyte levels before and after hemodialysis in dialysis patients. Materials and Method: A total of 112 patients undergoing hemodialysis three times a week for four hours for more than six months were included in the study. Before and after hemodialysis, 12-lead ECG, weight, arterial blood pressure, hemogram, biochemistry, and demographic data were recorded. Waves and intervals were calculated from the 12-lead ECG taken before and immediately after dialysis, and the relationship with serum electrolyte levels was evaluated. P
