Ekg says right atrial enlargement, cannot rule out anterior infarct. when compared to previous st now depressed in inferior leads. er discharged. why?

EKG can be inexact: EKG is a good tool to " rule out " conditions - so a normal EKG usually indicates normal cardiac function. The flip is not true - EKG with abnormal findings does not always indicate a problem - there are false positive findings more common in younger people and women. The clinical facts may then point to a presence or absence of a diagnosis . If you have symptoms see a Cardiologist
