The condition is called a Right Bundle Branch Block. You can go to the Mayo Clinic and read on it here.
In a nutshell, the right side of my heart has an electrical irregularity that causes the heart to pump inefficiently. The doctor says that since I was not being treated for hypertension or other heart related illness, the RBBB was probably brought on by the accident. The outside of my body was belted into the car, but as my body was being held in relative position, my gizzards and heart were banging around inside.
I now have had three "episodes" where I don't feel well and there is a heaviness in my chest (not pain, not insufferable). One in the car the moments after collision. One a few days later. One in the cardiologists office.
The cardiologist is taking a wait and see attitude towards my condition because I feel he thinks that it will resolve or not require invasive procedures or be managed. That's good because I take it personally when people want to poke around my insides to see if there is anything wrong. I'm not restricted on movement or anything, so that is good.
Sadly, I have no idea what the future holds. Fortunately, I don't have a Left Bundle Branch Block. That is worse than the Right one (see the Mayo Clinic article to know why). The fear of the unknown is unnerving.
I consulted a personal injury attorney and am considering hiring her to see if I have a case against the insured.
