Right bundle blockage

I was just to the doctor and they did an EKG and told me I have a right bundle blockage.  I am 55 y/o female, about 50 pounds overweight.  The symptoms I look at on the internet are nothing like I am experiencing.  My heart races 80 - 90 beats a minute sometimes, I get a cough, feeling of not being able to get a deep breath.  It is not the slow heart rate described.  When I go up 2 flights of stairs,(at work) my heart pumps out of my chest, I feel all panicky.  My doctor is ordering a stress test.  My husband is on the heart transplant list, and has recently had a change in his health.  I really attributed all of this to stress.

There are various degrees of block and I believe you have probably looked at the type III which is when no signal reaches the ventricles at all. In this situation, the ventricles generate their own backup signal but the heart rate is much slower than normal.
In the most common rbbb, signal is usually getting to the ventricle but via the heart tissue rather than the usual electrical route. The cardiologists have to establish if your rbbb is a problem but most end up being of no concern and rbbb is more common than first believed. A stress test will show if the heart is having arrythmia or other problems while under stress and provide valuable information. The main thing your cardiologist will be checking for is to establish if your heart muscle has been damaged, causing rbbb, through heart attack or something.
