Abstract

We presented a case of acute anterior myocardial infarction caused by left anterior descending artery occlusion in a patient with pectus carinatum. The electrocardiogram (ECG) on admission showed counterclockwise rotation and T wave inversion only in leads V1-V2. Computed tomography revealed that this patient with pectus carinatum had greater septal angle. Electrocardiographic counterclockwise rotation due to greater septal angle in pectus carinatum led to atypical ECG findings of acute myocardial infraction.

Keywords: Acute anterior myocardial infarction; Counterclockwise rotation; Electrocardiogram; Pectus carinatum; Septal angle.
