Question:
Could my RBBB be the reason I can't bike ride without frequent rest stops?
A recent 12 lead EKG revealed a right bundle branch block. I am a 57 y/o white male, 5,10 and 170 lbs, and an active cyclist. I ride 3000 to 5000 miles a year. My cholesterol and triglycerides are within normal levels. I also have hyperthyroid and I also smoke. Could this be the reason I cannot go anaerobic on the bike during hard efforts for more than 20 to 30 seconds, then having to soft pedal for a few minutes to rest? My last b/p was 128/79.

Right bundle branch block (RBBB) is an electrical finding only. Though it can be associated with high blood pressure, it can also be associated with significant heart disease, as well as with no heart disease. An echocardiogram (ultrasound) seems indicated and would likely be helpful. Good luck.
