[Guidelines for routine assessment of cardiologic surgical risk: electrocardiogram].

Cardiac complications are the main cause of perioperative mortality. A preoperative electrocardiogram and cardiologist's consultation are usually performed to get information about cardiac state of patients undergoing surgery and to prevent complications. In their study the Authors applied to 1715 patients undergoing surgery an evaluation schedule for the cardiac surgical risk, including an ECG as first-level test, performed systematically on the whole sample. The aim was to assess predictive value of this preoperative examination to verify its efficacy as routine test. Basing on results achieved, electrocardiogram is not routinely indicated before noncardiac elective surgery, but it should be requested for the patients having high risk of cardiac complications at an accurate clinical-anamnestic examination. Therefore, clinical judgement, that is the first level of any preoperative evaluation, should be the basis for ordering an ECG to be considered a second-level test.
