Persistent ST-segment elevation weeks or longer after MI is suspicious for ventricular aneurysm. A left ventricular aneurysm is a localized area of dyskinetic myocardium that bulges outward during both systole and diastole. Suspect an left ventricular aneurysm when these findings appear in the ECG of a patient who does not demonstrate symptoms suggesting acute coronary syndrome. However, one should also be vigilant for the presence of “silent” acute coronary syndrome. ++ FIGURE 23.12A Left Ventricular Aneurysm. This ECG was obtained on an asymptomatic patient with history of MI 2 years prior. (ECG contributor: James V. Ritchie, MD.)
