Hi
Welcome to the MedHelp forum!
Well typing in awkward position will not affect the electrical conductivity (ECG records this) and functioning of your heart.
I agree with Caregiver, that one cannot make an assessment of the heart based on a two year old report. What I can infer is that there was a problem, maybe mild occlusion of a branch of main heart arteries, or maybe a localized muscle problem resulting in hypokinesia or slower movement.
As suggested by Caregiver, please go to a cardiologist and get a recent 12 lead EKG, ECHO and TMT or treadmill test to understand the current condition of the heart.
Always remember—the heart gives signals before anything major. It is important to act now. Take care!
You should have another echo, because the information is two years old. I just had an echo and as a result went through all the possibilities, because it is somewhat frightening. You don't appear to have significant problems. That, of course is a relative term. As you know, the echo is a simple non-invasive procedure. The absence of symptoms suggests that you are lucky and is very positive information. You might ask for both a holter and a stress EKG. I would not worry too much as long as your blood pressure is under control and you are having no symptoms suggesting myocardial dysfunction, but it is a good idea to get another evaluation.
