Hi, as you describe, she had the abnormality in the E.C.G., since before this, or may be due to anxiety
Now the pain could be due to gastric irritation caused by the pills, which usually do to many people, and some people may feel it as chest pain
. So don't worry,about the chest pain. For difference in E.C.G. she can consult a cardiologist
to exclude any cardiac involvement. Thank you.
