What causes pressure in chest and shortness of breath with RBBB?
Patient: I had an EKg this afternoon and it showed a possible left atrial abnormality , and incomplete Right Bundle Branch block, and probable right ventricular hypertrophy. I have been extremely short of breath and I feel like I have an elephant sitting on my chest.  I take 100 mg. of metaprolol ER daily.  I do have moderate valve regurgitation.  What is going on here? Doctor: Hi,Right Bundle branch block with Right Ventricular hypertrophy & LA enlargement is definitely pathological. It might be because of increased valve regurgitation or new valve abnormality.You need to repeat the echo soon and if possible get a stress echo done too. You can follow up after the reports or if you have any more questions.Thanks
