Background: Cardiovascular complications are the leading cause of death in patients with end-stage renal disease (ESRD). Hemodialysis involves rapid electrolyte shifts and sudden fluid removal, which can affect ventricular repolarization and trigger arrhythmias in patients with ESRD. To enhance patient care, it is crucial to regularly assess cardiac function using noninvasive and painless methods, such as Holter electrocardiography (ECG) and routine cardiac ultrasound. These evaluations may inform improved prevention strategies to reduce the risk of elevated cardiovascular mortality rates. Methods: In total, 40 patients with ESRD on chronic hemodialysis (HD) were approached, and only 18 were enrolled from September 2024 to July 2025. Detailed medical information was provided, and written informed consent was obtained from the patient. The median duration of Holter ECG recording was 84.65 h, and cardiac ultrasound examinations were conducted. Blood gas samples were collected hourly during the second dialysis session. Results: Surprisingly, one-third of the patients opted to withdraw their consent for this painless investigation. No significant differences were observed in the QT and QTc intervals between the dialysis and non-dialysis days (p = 0.184 and p = 0.446, respectively). However, a significant increase was observed during the first 3 h of dialysis when analyzing the intradialytic period. Conclusion: Some patients showed clinically significant changes in QT and QTc intervals during treatment, which could not be confirmed statistically. Although we did not formulate a hypothesis, it is essential to recognize that patient compliance significantly influences the cardiovascular outcomes of individuals undergoing hemodialysis.
