I am a 36 year old female and was diagnosed with LBBB five years ago. I have always exercised regularly and never had problems heart-wise. I was exercising and felt a big, very quick inflation-deflation feeling in my mid chest. It did not hurt but it immediately put me on alert. I got a stress test done and it indicated LBBB and an EKG that indicated sinus arrhythmia. The doctor told me that I could continue to exercise as long as I did not feel weak or faint. I wanted a second opinion in light of the fact that doctors want to see the bundle block resolve and it is unusual to be able to feel it. Does continuing to exercise also make the bundle block continue and not resolve and does it put more stress on the heart muscle?
Could pre-ecclampsia cause LBBB?
