Highlights the importance of recognizing subtle ECG signs of atrial infarction to anticipate severe complications like arrhythmias and pump failure.
May prompt ECG vigilance for atrial infarction; leaves open whether recognition improves outcomes.
A case of atrial infarction in the setting of an acute infero-posterolateral and right ventricular myocardial infarction is reported. Although often only a subtle ECG sign, this finding must make the physician aware of possible complications, such as arrhythmias (atrial fibrillation, sinus bradycardia, and AV conduction disturbances), pump failure of the right and left ventricle, atrial wall rupture, and thromboembolization.
