Overview
Electrocardiogram
- The presence of q waves suggest a prior MI to account for the enlargement.
- ST segment elevation would suggest either ongoing or resolving ST Elevation Myocardial Infarction or Myocarditis or Pericarditis.
- The EKG may suggest signs of left atrial enlargement, right atrial enlargement or right axis deviation which may point toward a specific diagnosis.
