Thank you for your query at DoctorSpring.com
I understand your concern.
Yes, I have reviewed your entire history and the ECG. He has Right Bundle Branch Block, however, the good thing is, RBBB is not that serious. The left sided branch block is more serious and can lead to CVD in the future. So at present it seems his pain is due to GERD, and I will advise him Cap. Omeprazole 20 mg twice daily once before breakfast, and once in the evening.
You can get repeat ECG every 6 months, just to monitor him, since he has a family history of heart problems.
Hope this was helpful,
Feel free to discuss further,
