Brief Answer:
It doesn't seem to be RBBB.

Detailed Answer:

Hello!

Welcome and thank you for asking on HCM!

I reviewed both of your ECG recordings (23rd July and 6th August; though the latter ECG is of sub-optimal visual quality), and I am glad to confirm you that, they don't fulfill the criteria for RBBB:

- QRS duration is less than 120 ms;

- absence of typical R wave morphology in V1-V2 (rsr′, rsR′, or rSR′ broad monophasic R wave or qR);

- absence of S wave duration greater than R wave or greater than 40 ms in leads I and V6;

- absence of R peak time greater than 50 ms in lead V1.

So, to conclude, I would say that your ECGs doesn't confirm any typical patterns of RBBB.

If you have a better quality ECG recordings, you are invited to review it also.

Hope to have been helpful to you!

Feel free to ask me whenever you need!

Greetings!

Dr. Iliri
