Incomplete Right Bundle Branch Block on ECG?

[Ionblue]

I'm a 25 year old, otherwise healthy male.

I was recently having some minor chest pain which my GP thinks is Costochondritis, she had me take an ECG test just to be safe.

Today i got my results and she said it is a very healthy ECG. She mentioned that there was an Incomplete RBBB on the ECG, but she assured me it is not a problem and relatively common in normal and healthy people. She spoke to a cardiologist about it and he said that my QRS duration was under the diagnostic criteria and that is is not significant enough to indicate a problem.

She told me not to worry but I did some research anyway and I am still concerned, I was looking for a second opinion from a medical professional/anyone with knowledge in the area as to whether this finding is a problem and/or related to my chest pain?

Thank you.
