djis,
thanks for the post. I'm assuming your ejection fraction was determined by an echocardiogram or ventriculogram.
An ecg is an electrical picture of the heart. An isolated ecg report doesn't tell you all that much out of the context of the patient sitting in front of you. What I can tell you from your written report is that you have changes on the ecg that can probably be attibuted to your old heart attack. The interpreter of the ecg has to make comments regarding all aspects of the ecg based only on the paper in front of her. So on your ecg you have changes in some of the recording that can be reflecteive of a person having ischemia. However, especially in patients that have had heart problems in the past, this is a common finding.
So I can't really tell you much on how those results look. However, given you have an abnormal ecg, I think its important emphasize that it would be useful for you to have a person copy of your ecg for comparison if you were to need to seek medical attention
hope this helps.
