An ECG rarely tells the whole story and often show "glitches". I had one for many years but it was never investigated further. Several AMEs said it was due to ME being wired differently; ie the electrical pathways in my heart were slightly different. That's what they might have meant for you?
The thing about SRG is that they have to have a reason for things; they can't just pat you on the head like a GP and tell you all is well. After all, people's lives may depend on you sometime so they want to ensure that all is well to the best of their ability.
I find it somewhat disturbing that you are getting worked up and using bad language. If you have that attitude you will not progress far in aviation, which demands calm professionals. Just calm down, do the tests and see what happens.
Good luck and I hope all will be well.
