No, : No, left bundle branch block (lbbb) is not hereditary. The heart has specialized tissues that conduct the electrical impulses that stimulate the heart to contract. In your case, one of the pathways of electricity called the left bundle is blocked. This shows up as an abnormality on the ekg. Lbbb is almost caused by underlying heart disease of some variety. Because you are describing "mild heart attacks, " your doctor appropriately ordered a nuclear stress test to see if you have coronary artery disease (cholesterol plaques in the heart arteries). And yes, it is common to have side effects like nausea, chest tightness, and anxiety during the test. Treatment will depend on what they find, and more tests may be needed. It is very important that you follow up with your doctor for the results.

Not hereditary in : General but conduction abnormality may occur with increased heart rate. Talk to your physician or a cardiologist.
