The structure of the dataset is in tabular form and includes basic information about the subjects of the study, comorbidities, postoperative outcomes, and 24-hour dynamic electrocardiogram results. The dataset has great potential for reuse in data analysis. We have anonymized the subjects, so there are no ethical issues.
