Electrocardiographic manifestations of ventricular aneurysm

Left ventricular aneurysm often causes ST segment elevations in indicative infarct leads which persist after resolution of the infarction. Such findings may be difficult to differentiate from other causes of ST segment elevation, particularly acute infarction. A review in the American Journal of Emergency Medicine describes the electrocardiographic findings of left ventricular aneurysm and focuses on the differentiation form acute infarction. As opposed to acute infarction the ST elevations of ventricular aneurysm tend to be accompanied by well developed Q waves and reciprocal changes are lacking.
