Introduction: Preexisting electrocardiographic abnormalities may limit accuracy of continuous electrocardiography (cECG) for ischemia determination. The American College of Cardiology/American Heart Association published criteria for the exclusion of unsuitable cECG curves from ST-segment interpretation. These criteria consider medication and 12-lead ECG findings (medication- and 12-lead ECG-based criteria) and cECG lead characteristics (cECG-based criteria). Methods: We recorded cECG in 300 patients undergoing major noncardiac surgery. We determined postoperative troponin and 12-month outcome. We compared the associations of cECG-detected ischemia with troponin and 12-month outcome with and without adherence to the criteria. Results: Adherence to the medication- and 12-lead ECG-based criteria enhanced the association between troponin and perioperative ischemia in CM5 (odds ratio, 3.74; 95% confidence interval, 1.88-7.44) and 7.03 (2.67-18.49), respectively; P = .049). Similarly, the association between ischemia in CM5 and 12-month Outcome tended to increase (P = .081). Conclusions: Applying the guideline criteria for the interpretation of cECG enhanced cECG diagnostic value in surgical patients. (C) 2009 Elsevier Inc. All rights reserved.
