Prognostic Value of Preoperative Electrocardiogram in Low-Risk Patients Undergoing Surgical Intervention and General Anesthesia.

Background: Patients aged over 50 years require four times more surgical interventions than younger groups. Many guidelines recommend the performance of preoperative electrocardiogram (ECG) in this population.

Objectives: To determine the value of preoperative ECG in patients aged over 50 years and classified as ASA I-II (surgical risk).
