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.
- Shown below is an image of an EKG depicting right atrial enlargement.
- Shown below is an image of an EKG depicting biatrial enlargement.
