Re: how to get my doctor to give me an ECG
Yes, an ECG can only really tell if you are having a heart attack/angina attack etc at that moment in time. It really has little to no use in ascertaining the functioning of the heart on a day to day basis or if any form of heart disease or disorder is present.
As has been rightly said, we all tend to suffer with flutters and the like but obvioulsy health anxiety sufferers are far more highly sensitised and attuned to their bodies and these sensations and therefore we notice them far more and then over catastrophise them.
Just reading your post it seems you are worried about dieing suddenly and a heart issue probably seems the most likely way this is going to happen. I would suggest concentrating your thinking around the sudden death worry, where it comes from and why it is debilitating you so much as opposed to the heart issue. As hard as it is constructive thought and reflection on the true core issue is far more beneficial than chasing your tail with aimless worrying on the way your anxiety has decided to manifest itself to you.
