Prevalence and associated factors of preoperative abnormal electrocardiography among older surgical patients in southern Ethiopia: Multicenter cross-sectional study

Our study shows that older patients are more likely to have an abnormal ECG before surgery, regardless of symptoms or risk factors. Therefore, it is suggested that all older patients undergo preoperative ECG screening. Further prospective cohort studies are needed to investigate the impact and outcome of patients with preoperative abnormal ECG.
