Thanks! that was a perfect answer. And the one I didn't run accross on my own. This almost exactly what my doctor said, but being at the Cardiologist must have made me nervous enough not to get this as clearly as it was in this reference.
From your source:
"What is bundle branch block?
Normally, the electrical impulse travels down both the right and left branches at the same speed. Thus, both ventricles contract at the same time. But occasionally there's a block in one of the branches. This doesn't mean that one of the ventricles won't contract. It just means that impulses must travel to the affected side by a detour that slows them down. That means one ventricle contracts a fraction of a second slower than the other. Usually if there's nothing else wrong, a person with bundle branch block shows no symptoms. But since we can record the electrical impulses through the heart with an electrocardiogram (ECG), a bundle branch block shows up on the ECG as an abnormality.
If you have bundle branch block, it may have only been noticed when you had an ECG. You may feel fine. However, there's something wrong with the blocked bundle. For instance, it might mean that a small part of your heart isn't receiving enough oxygen-rich blood. That's why, if you have bundle branch block, your physician will want to see you regularly to be sure no other changes occur. You may have bundle branch block for many years and still feel fine, but it's important to have regular check-ups. "
Amazingly similar! Thanks.
