im a 37 female

hi i posted u this ekg repaort like a week ago i went to see a cardio an he did a echo an it came normal i have no enlarge ment...im happy bout that...1 thng im conern is the right bundle branch block.....Is this sumthng to worry bout or could cause sumthng serious later?? thnx alot!!!!

the right bundle branch block will not cause you any problems, as your echo did not demonstrate any structural heart disease.
there is nothing serious about this and you can relax!

Hi,

Just to explain this a little, a right bundle branch block is a normal phenomenon. In your case, I don't even think it's complete, because your QRS complexes are nice and narrow.

Question is, do you have an old EKG to compare? If you do, the doctor will see if this is something that has developed now, or if you're born with the IRBBB (incomplete right bundle branch block).. long word ;)

I know it's scary to see your EKG stamped "abnormal". I've had my share of borderline and abnormal EKG's and my heart is still healthy, really healthy. An echo I had done recently actually amazed the cardiologist.

By the way, did your cardiologist explain the short PR interval? Shortened PR interval can be caused by a condition that can be experienced as runs of rapid heart rate, but any cardiologist should see this by looking at your EKG. If he didn't, you can relax.

The rbbb I have nothing to worry bout???? wont cause fatal or anythng serious???

[rachael60]

is a IRBBB AND A RBBB 2 diffwewnt thngs or the same???

Hi

Right bundle branch block (RBBB) is a condition where the electrical impulses aren't conducted to the right ventricle (right heart chamber) through the normal pathway. It doesn't mean that the right ventricle doesn't work (it does) because the entire heart can lead electrical impulses and the RV will be activated, just through other pathways. It's a delay that's visible on EKG but we're talking milliseconds. In the case of an incomplete RBBB (which seems to be your case but a doctor should confirm that), the conduction time is normal but there are still signs on EKG of a slight "late activation" of the RV.

In other words, the EKG leads that "see" the right ventricle notice some RV activation after the left chamber (LV) is activated.

We all have RBBB when we're born, actually, but in most of us it corrects after a short time. My cardiologist told me that 5-10% of us have this IRBBB/RBBB patterns on EKG and that it's a "normal abnormality" just like PACs or PVCs. It won't lead to anything dangerous.

But again, I'm no doctor. Your PCP, or the cardiologist on this forum, can tell you this for sure.

I talk to him last nght he says that i have a IRBBB and nothin to worry but wat im scared bout is rbbb same pattern is brugada syndrom (syndrome) so now im nervous....is that true???

Hi,

Now you really have to stop reading up on electrophysiology! That's the most important message in this post! :)

Anyway, I assume you've read so much about this stuff now so I'm using a bit more advanced terms (from when I used to do the mistake you're doing now; reading too much electrophysiology)

Brugada pattern is an atypical (I)RBBB pattern, with major ST elevation in leads V1-V3. The ST segment is sloping down towards the T wave or has a saddleback pattern that can imitate acute MI.

You can say: Possibly 1 out of 500-1000 (not completely sure how common it is) RBBB patterns is a Brugada pattern. And the cardiologist (and the machine) would without doubt recognize it. It's something you're born with and it causes severe arrhythmias. You would have noticed it by now.

Thinking like this is similar to thinking every sensation in your chest is a heart attack. You need to stop this now :)

Thank u for ur time and yea i know i need 2stop it....u thnk my cardiologist would know if i had brugada??? thnx again!!!

[is_something_wrong]

If you had Brugada patterns, he would without doubt see it. i'm not even a doctor and I can recognize this pattern. i'm sure a cardiologist would!!

[rachael60]

heyy 1 more quiestion....a oral flecinide test take an ekg every hour for 3 hours ...does that test show brugada ?? thnx!!!

[rachael60]

will a oral flecidine test show brugada?? I took a ekg every hr for 3hrs ...would that rule out brugada????

[CCF HeartMD-2]

Hello, thanks for your question
The Brugada syndrome is a mutation of the sodium channel (SCN5A), and therefore, medications which block sodium channels(i.e. flecainide) may be a given as a provocative test to bring out latent electrocardiographic forms of Brugada syndrome.

[rachael60]

my cardio says the ekg came out negaitive so does this mean i dont have brugada???

[CCF HeartMD-2]

I would rest assured that you do not have Brugada syndrome and do not think that you need to undergo further testing (i.e genetic testing).
