Hi, I am diagnosed with RBBB with no other major heart problems. I just wana ask if it will, in any way affect me in my everyday life or occasional activities. I m a male, nearing 20 years old. 1) I m a sporty person but i find that it s difficult to improve my stamina, can it be because of RBBB or am i just not pushing hard enough? 2) Since young, i feel really uncomfortable when i take roller-coasters. Instead of feeling the thrill like others, i feel more like, uncomfortable and wants it to end. There s a funny sour feeling at my heart.
