It can mean a variety of things. “Low amplitute” on your EKG can be caused by a pericardial effusion or severe coronary artery disease (CAD), or low thyroid function. In your case, a pericardial effusion (fluid in the heart sack pressing on your heart) needs to be excluded, best done with an echocardiogram. For follow-up of your heart attack you should have a stress test as well to determine whether there is evidence of insufficient blood supply that requires further treatment.
Since your heart attack was caused by CAD, your treatment options should be considered, that at a minimum should include changing to a healthy life style, that usually result in a choice of medical therapy, and/or an interventions such as a stent or CABG.
Hope this helps,
