I am not going to comment on your "abnormal ECG", but I doubt that your neck pain is heart related. Why? Because I have exactly the same problem. During an MRI they noticed a slight protrusion of the C4. Not enough to warrant surgery, but enough to cause problems such as you describe. When you consider that you walk with your legs and not your neck, it's hard to believe, but that's what it is.
Hi Vinay,
Why did you have the angiogram? Do you experience chest discomfort and if so, under what circumstances?
