Can right bundle branch block cause tachycardia?
I went to my doctor because I was having a resting heart rate of 130 at work, whereas as home it is about 70-80. I had an ECG done which showed I had right bundle branch block, but my heart rate at the time of the ECG was 90. My doctor has requested I try and get an ECG at work (I work in a hospital) when my heart rate it higher. He didn't explain anything about the right bundle branch block, just got a ruler out and measured the waves on the ECG and told me not to worry.
Could the tachycardia I am experiencing be anything to do with this right bundle branch block? Or are they unrelated, and should I be worried about the right bundle branch block in itself? I do sometimes get chest pain and out of breath for no reason, and am wondering whether this may have something to do with it too?
----------
Well lets start with Donna's answer first. "The tachycardia probably caused the BBB. when your heart rate goes so high it is causing ischemia (decreased blood supply) to your bundle branches and you might have a rate related bundle branch block."
Oh dear! It's quite evident from the history this patient has given that it most likely isn't rate related RBBB
Now, BBB that occurs on the right side is more likely to be a variation of normal, and BBB that occurs on the left side, is more likely to be pathological. I suspect the RBBB is unrelated to your elevated HR and was just found by chance on your ECG.
Given the fact your increase in HR seems to only happen at work, would strongly point towards this being an anxiety related problem. However, it's wise to have a work up. When we see BBB on an ECG it always warrants further investigation, but it's most likely a variation of normal. The holter monitor study is a rational suggestion. (

i have a incomplete right bundle branch block & having painfull cramps in my plams(they turn blue)?
28 years old, 2 children and living with high stress!
----------
Get rid of the stress (knock off the kids, collect the insurance, move to Hawaii).
I'd say . . . see the cardiologist -- there's an issue. (

is Bundle branch block fatal?
So my mother had been having chest pains lately so she went to doctors today and did her usual check-up and the doctor suggested a EKG. She was told she has "Bundle branch block" brought on by her lupus, and was told not do anything strenuous or you may pass out. Now my mom is getting overworked about this and very scared that she will die soon at the age of 49. My mom has always been healthy - never smoked, drank or anything then one day this happens. So i'm a bit paranoid as losing my mom at 13 doesn't sound great.
Does anyone know if Bundle branch block can be fatal?
She has a appointment with the cardiologist in a week, does anyone know what they would typically do? Can this condition be resolved?
Thank you very much.
----------
I imagine that if the block was severe and left untreated that it could be fatal. But if your Mom is overall healthy (despite the Lupus), it's probably a very manageable condition.
The cardiologist will probably order more testing to make sure she doesn't have an underlying heart issue and will have her come back in a few days to a couple weeks to discuss the test results and what the plan of treatment is.
I've attached some links below for you AND your Mom both to read. It's not like she is going to drop over with a massive heart attack; it's a condition that warrants further investigation and possibly some medication and in extreme cases, possibly a pace maker to help the heart get the right electrical impulses at the right time.
Take one step at a time and go from there. Educate yourself and your Mom and that will help reduce the worry and she will be better able to discuss the problem with her doctors. The more information she has, the better decisions she will be able to make about her care.

Left Bundle Branch Block chest pain with exercise?
I have exercised my whole life. I have always been in good shape, until after I had my children. I started weight watchers and took up exercising again and discovered I had horrible chest pain when I would walk up hills or when my heart rate would reach above 150 bpm. I am 38 years old. I had a stress test and they discovered the left bundle branch block and I'm scheduled to see a cardiologist this week. What are my chances that I'll be able to exercise without pain again? I don't smoke, cholesterol and BP is in great shape. I don't know how this could happen at my age. I am feeling sorry for myself and I'm feeling chest pain quite often these days and I don't know if it's always been there or if I'm making it up. I can't wait for this to be over. This is very stressful.
----------
I was recently diagnosed with this condition. I am 58 years old and very active as yourself. Similar good health situations. Resting heart rate of 55, normal blood pressure. Walking the same place as I have for 2 years this spring I had the same chest pain and the feeling of a irregular heart rate when I get above 147 beats. My GP put a heart monitor on for 24 hours and the results sent me to a cardiologist. They first thought I had a blockage. A stress eco cardigram showed a healthy heart, but the heart rate showed the LBBB. I did not have the pain during the test. I live at 8,000 ft and I am not sure if that makes the situation worse? My doctor said a beta blocker might help, but didn't really think there was anything that would help but to keep my heart rate lower than 147. I have been on the blocker for 3 months, I have not had any pain since, however, last week I was running where I usually walk, not sure what my heart rate might of gotten up to and I had some significant pain. I really don't like the pain, as it was explained to me that that means the blood is not flowing well through my heart.. I am going to get a heart monitor for exercise to try to keep the rate below or near 147.. Let me know what you learn from you DR. I have been having trouble learning as much as I would like . My dr said this was common with woman my age.. but you are younger.. (

Incomplete Right Bundle Branch Block
Thank you in advance for any inputs!
----------
I never read or believe the computer analysis of an ECG because it is frequently wrong,
Do you have a copy of the ecg and a scanner I will take a look at it.
The cardi ologist should review it.
I don't believe in borderline anything.
Either you have a BBB or you don't (

mechanism of t wave inversion in bundle branch block?
It is known as secondary T wave change. The change in sequence of depolarisation (QRS) is responsible for change in sequence of repolaristion (T wave). (

Is Bundle Branch Block serios?
I have been diagnosed with bundle branch bloc minor. How serios is this?? Any one have the same problem... Is minor not major..
----------
Rhianna has given a very good and comprehensive answer. I have nothing to add to it other than your MD has diagnosed MINOR bbb, so apparently the one who found it on your ekg knows it is MINOR and therefore not problematic at this point. If it were a serious concern, your MD would not have called it minor. If it were a serious concern your MD would have told you...don't worry. (

what does an incomplete right bundle branch block mean on an ekg report?
a "bundle-branch block" is a condition in which the heart's electrical system is unable to normally conduct the electrical signal...
Causes, significance, and treatment
Bundle branch block (BBB) is a relatively frequent finding on the electrocardiogram (ECG). Sometimes BBB itself needs to be treated; sometimes it indicates significant underlying cardiac disease that needs to be treated; and sometimes it has so little significance that no treatment is necessary at all. In this article, we will review bundle branch block, its significance, and its treatment.
What are the bundle branches, and what do they do?
The bundle branches are an important part of the cardiac electrical system, the system that coordinates muscular contraction to assure that the heart works efficiently as a pump
Right and Left Bundle Branch Block
Right bundle branch block (RBBB)
In RBBB, the right bundle branch no longer conducts electricity. Therefore, as the electrical impulse leaves the His bundle, it enters left bundle branch only, and is carried to the left ventricle. Then, from the left ventricle, the electrical impulse finally makes its way to the right ventricle. As a result, the two ventricles no longer receive the electrical impulse simultaneously. First the left ventricle receives the electrical impulse, then the right.

what is a Right Bundle Branch Block (RBBB). It was read from an ECG test. What are its risks?
Hard to explain with out going into a bunch of detail...
Bundle branch block is a condition in which there's a delay or obstruction along the pathway that electrical impulses travel to make your heart beat. The blockage may occur on the pathway that sends electrical impulses to the left or the right side of your heart.
Bundle branch block can occur in people who appear healthy, but it may be a sign of another underlying heart problem. Bundle branch block sometimes makes it harder for your heart to pump blood forcefully and efficiently through your circulatory system.
Although bundle branch block itself often requires no direct treatment, you'll need treatment of any underlying health condition that could cause bundle branch block, such as heart disease.
RBBB can be caused:
-Congenitally, a heart attack, a virus, high B.P. or a clot in the lungs.
RBBB can cause:
-Slow heart rate, heart arrhythmia, cardiac arrest. (

what is ischemia, and the significance of a right or left bundle branch block?
I also would like to know (other than the obvious symptoms of a heart attack) if there are other physical indicators that I would experience with either a bundle branch block, or ischemia? My medical history is that I am a fairly active 56 year old African American male with chronic seasonal asthma. When I went to the ER for my asthma and had an EKG the inverted T- wave found. It was suggested that I have a stress test as a diagnostic tool. Is this test a good recommendation for an asthmatic? I thank everyone who is taking the time and patients to help me with my inquiries.
----------
Ischemia means deficiency of blood on a part, due to functional constriction or actual obstruction of a blood vessel. Myocardial ischemia: deficiency of blood supply to the heart muscle due to obstruction or constriction of the coronary arteries.
* Inverted (or negative) T waves can be a sign of coronary ischemia, Wellens' syndrome, left ventricular hypertrophy, or CNS disorder.
* When left bundle branch block is present, the T wave should be deflected opposite the terminal deflection of the QRS complex. This is known as appropriate T wave discordance.
In Left bundle branch block, activation (contraction) of the left ventricle is delayed, which results in the left ventricle contracting later than the right ventricle. (
