I was diagnosed with incomplete rbbb. I always have palpitations, and light headedness. It feels that sometimes i may collapse but then it goes away or if i vomit it makes ne feel better. And then i always have trouble breathing. And im prevnant as well so im not sure whats causing all the symptoms. Is it possible that its because of irbbb?? I was checked by an internist but he said that there was a mistake in the reading of my ecg. But im not sure. So i wanted to get another opinion. Because they cant tell the reason why im having shortness of breathing, dizziness, light headedness.
