case_images: Electrocardiogram (ECG) showed a QS pattern in leads I, aVL, and V6 (Figure 1), and echocardiogram confirmed normal intracardiac and coronary anatomy, moderate left ventricular dysfunction (EF 45%), and a thrombus at the level of the left atrial appendage, leading to the working diagnosis of acute myocardial infarction, possibly secondary to the atrial thrombus.
