Bundle Branch Block
Hi, im a 19 y\o male, and about 3 years ago I was told I had a incomplete right bundle branch block. Needless to say I developed aniexty from this because I was worried, and didnt really know what it was. I had some tests done to try and ease my worries. I had some ekg`s, blood tests, echocardiogram, stress test, and wore a holter monitor for 24 hours. Anyways, I used to be very active, but lately this is starting to bother me again and im worried about weather or not I should be excerising too much or not. When I seen the cardiogolist, I was active at the time, and he said to continue what im doing and not worry. I recently read some problems that are associated with a bundle branch block, and im pretty worried. Just wondering if anyone has any infomation about bundle branch blocks.

I don't have a lot, but keep being active. Stopping is about the worst thing you can do.

I have leftBBB.  Mine kicks in at a certain rate and I can feel it. It feels out of rythym and I have to stop what I'm doing,  I can tell you from experience, too much info is not good.  It will scare you.  With RBBB you have a better chance of death by getting hit by a train.
So stay off the tracks and quit worrying.
What are your symptoms?  Can you feel them all the time? Is yours rate dependent?

I've had some pain and chest tightness on the left side with left block and enlarged right atrium and enlarged left ventricle on ekg.  I have low oxygen from sleep apnea.
are there drugs like ACE drugs to treat this?

An incomplete RBBB can be common for young, healthy individuals, especially athletes.  If a cardiologist cleared you and told you not to worry about it, then I wouldn't.

Today I had a pre-op checkup to get approved for upcoming cataract eye surgery. I'm 63.
An EKG was done and detected "right bundle branch block" but without any symptoms, so I was cleared.
Just noted it to watch in the future.

I've read that this condition can happen to young 20 year olds, and even prospective Air Force pilots are cleared with this condition, so I guess it isn't considered serious unless accompanied by other symptoms?  The only way it was detected was by the EKG which was the first I've ever had.  The regular listening to the heart beat by the doctor now and in the past was normal.

Yes sir, not too much to worry about. In terms of symptoms, you should not be symptomatic unless you were to also develop a left bundle branch block, in which case you would get pretty sick in a hurry.

Since you've never had an ekg before its worth mentioning that a significant portion of right bundle branch blocks are actually something you can be born with. There's a real possibility that you've had this problem to some degree your entire life and simply didn't know about it.

That said the right bundle is extremely small and fragile, 2-3mm if I recall correctly. As such it tends to break all the time. Thankfully, the left bundle on the other hand is significantly (2-3x) thicker, and also significantly more resilient and more difficult to damage. As such the majority of cases such as yours don't wind up developing into the more concerning 'complete' heart block.

Its the folks with left bundles that need a little more scrutiny.

In all honesty at 63 years old, most folks in your age group have some degree of Sinus node or AV nodal dysfunction. So while an isolated right bundle branch block certainly isn't a 'perfect' bill of health, its a lot better then what one would typically expect to find among your peers.

In short, you're doing pretty good for your age and I wouldn't worry too much about it.
