Recognition of MI on ECG outside the acute phase is challenging; Q waves are absent in a significant proportion of patients and may reduce or disappear over time. Although ECG is widely used in the initial assessment of previous infarction, studies to validate ECG using CMR as a reference in the context of chronic coronary disease are limited.</p><p><strong>Objectives: </strong>To evaluate the diagnostic performance of ECG in detecting and locating CMR-defined MI.</p><p><strong>Methods: </strong>This study included 352 individuals who underwent CMR and ECG, 241 patients with previous MI confirmed by CMR and 111 controls with normal CMR. Their ECG tracings were analyzed by 2 observers, who were blinded to the CMR, for detection and location of MI following to the Fourth Brazilian Society of Cardiology Guidelines on the Analysis and Issuance of Electrocardiographic Reports.
