- In this video we review a not infrequently identified change on the electrocardiogram. This test looks at the electrical patterns of the heart from electrodes placed on the skin around the body. Sometimes, you may be told that this test has shown a 'bundle branch block'. Often, people confuse this with a 'blockage' in the arteries around the heart. This is not the case and here Professor Barlis reviews what the bundle electrical pathways in our heart are and the two major types of changes seen causing a right and left bundle branch block. Information is presented for educational purposes only and always remember to seek independent advice from your local health care professional.
Thank you for the info.
My wife was just diagnosed with a " Left Bundle Branch Block" as she had almost fainting moments when standing after crouching down .
thank you for sharing Marquis. I am glad to hear she is receiving attention to these symptoms, no doubt they can be very frightening when we are experiencing something new like that. Best wishes.
Very nicely explained..Thank you so much
Thank you for this discussion
very informative ! thank you so much ♥️
Thanks for the video. I was diagnosed with left bundle branch block because I passed out. Problem is, I already have Diastolic Dysfunction.
very good...!
I’ve just been diagnosed with major LBBB, my doctor has told me that I can die at any time.I never expected to get cardiac problems, being a sportive person, working out 5to 6 times per week, eating clean, not drinking or smoking, no fizzy drinks at all, I’ve been like that my whole life, I’m 46 years old;I don’t know if i still can to do sport at the level and intensity I used to do, or if I can have a coffee…what do you think i can do doc while I’m waiting for medical tests? I’m feeling exhausted non stop, dizzy, short of breath and having a constant chest pain.
Thank you for what you do for us!😊
Thank you so very much.
Ischaemic heart disease is a major factor within my family. After leading a clean life, I was diagnosed with the same. Although saddened, I was not surprised.
More recently, I have been diagnosed with a left bundle branch block along with a deviated left axle.
I am completely asymptomatic and, generally, three times a week, attend an intense aqua aerobics class.
Due to various reasons, I have been unable to attend for the major part of ‘23. I do intend to return in the New Year. However, when asking if this is no longer a viable option, I have been left with uncertainty.
Would you, in your expert opinion, advise against this or may I continue please?
Thank you very much.
So left bundle is more serious ? My mom just got diagnosed and I am very scared/ worried pls answer thank you for the videos !!
I've just had a ecg showing T wave inversion in lead 3 and flat Ts on AVF and intraventricular conduction block ,could you explain what this is and what side of the Heart thank you.
I was diagnosed with a Right bundle branch block last night because I ended up passing out at work hours before
Thank you for sharing and for watching the video. Hope you found it relevant.
I have HOCM now HCM, LBBB, L V Diastolic Dysfunction, Gaded I last year this year they call it indeterminate? Palpitations are driving me crazy, very fatigued, starting to retain fluid in lower legs.
Thank you for the interesting discussion. Since RBBB is an electrical issue, and AFIB is also an electrical issue, what are the concerns about a right bundle branch block when one has persistent AFIB? How much does RBBB exacerbate AFIB?
Great question Steve, you are correct, both are seen to relate to electrical issues within the heart. There is no direct link however between Afib and a right bundle branch block. Both can occur in isolation or together and show a slightly different issue within the heart (RBBB for example involves the electrical wiring at the bottom part of the heart whereas Afib originates from and around the top chambers of the heart. We will delve into this further in an upcoming Q&A!
@@HeartMatters I look forward to hearing more from you on this. I'll also add to my concern, that because the ventricles aren’t working at exactly the same time, a right bundle branch block creates an irregular heartbeat (arrhythmia.). And in AFIB, the signals in the upper chambers of the heart are chaotic. As a result, the upper chambers shake (quiver). The AV node is then bombarded with signals trying to get through to the lower heart chambers (ventricles). This causes a fast and irregular heart rhythm.
So now we have an irregular heartbeat from a RBBB, and a fast/irregular heart rhythm from AFIB. So combined, they to me are concerning.
I just got diagnosed with this today. I had no symptoms and problems of any kind. I only found out about it when I went into surgery for a septoplasty. Of course, they stopped that and referred me to a cardiologist. I see him or her on the 25th. I feel fine! I regularly go to the gym and I ride my bikes between 200 to 400 miles a week. Let me tell you that this news is a shocker! Do you think my physical activity could have brought this on? I don't want to slow down my cycling as I'm very competitive. I can give up the weights, but not my cycling.
Thanks for your comment! Your description is very common, many people end up finding out about a bundle branch block by accident so don't panic. There are some simple tests your doctor can arrange to assess how the heart is working and provide you reassurance!
Test such as echocardiogram, exercise stress test and some cardiac enzymes may be taken to test your cardiac function. If all test performed are within normal, your condition will not cause any effect on your activity daily living.
Same thing happened to me
They gave me crt treatment, I feel great👍
Thank you so much I have CRBB and my diastolic BP is low around 60 is there a possibility that is connected or caused by CRBB?
hi sir my dad having left bundle block and echo they checked it pumping capacity is good... please suggest left bundle block is serious or not...
Gr8 video 👌
In case one has LBBB & 2D echo is normal then Dr says the person is fine. Heart muscles also conduct the signals, so even if one half works that fine, as per medical science.
Bt I never understood with so much technology & medical advancements, why this can't be corrected/cured? Pace maker I guess is only needed when situation is severe & pumping becomes very low. Isn't at the end bundle branch block is jst an electricity wire problem? Don't we replace electric wires of home if they get broken or become old?
You really raise a great question. One new method we are now seeing for those patients who need pacemakers is to try and use the pacemaker leads to restore normal conduction. I have been amazed that things like left bundle branch blocks can be corrected using such new pacing methods (e.g. physiological pacing). I will have an expert on this talk to us about this very topic, thanks for your feedback!
My mother's ECG shows a interventricular conduction defect and left bundle branch block without MI, with slight chest pain. So what should we do now...is it a serious condition??...please answer...
Hello Himanshu, always good to get any symptoms assessed by your local doctor as there are some simple tests that can be undertaken to provide reassurance about what is causing a bundle branch block and whether any particular tests or monitoring may be useful.
I couldn't find much but I was curious if a bilateral branch block could actually happen simultaneously or separate times on the same ecg?
excellent quesion, the heart's conducting system is quite robust, when there is such a significant block affecting multiple pathways then most often symptoms will result. In cses where there is complete heart block, often pacemaker devices may be needed to help support the heart beat.
@@HeartMatters if there is "damage" to the his bundle, (His-Purkinje System) how would you suspect? Would it result in junctional premature complexes, junctional and fascicular tachycardias, bundle branch reentry (BBR), and the role of apparent conduction in various forms of supraventricular tachycardias (SVT) with or without involvement of accessory pathways? And what would cause this in the his- purkinje system as far as damage? Was kind of curious, if maybe a patient with a his pacemaker had a misplaced, dislodged or an excess amount of "scar tissue" on a his lead(coil/electrode) could potentially be a cause? I understand if you can't answer this.
Yep I was diagnosed with Idiopathy Cardiomyopathy with a left branch bundle block.....i was 28 i'm now 55. I'd say I'm bucking the odds???
Zec sun block
I've been experiencing fatigue and shortness of breath. An EKG showed a past silent heart attack and a treadmill test exposed LBBB. Is it safe for me to travel or should I stay close to home?
Bundle branch block on the EKG can create some anxiety. There are some more sensitive tests like echocardiograms / MRI /nuclear scans that can also provide more details as to exactly what is going on and whether any further treatments may be useful.
If i have an Right bundle branch black can i do exercises?
Thank you Ariane for sharing your experience, in general, bundle branch block does not limit exercise and we know that exercise is key to keeping excellent heart health. Please always check back with your doctor for any specific advice.
My 13 year old son was just told he has LBBB on his EKG and referred to cardiology. Everything I read says this in children is rare and sign of a heart condition. Is this true? I’m worried!
Hello my name is Richard my 9 year old daughter was just diagnosed by EKG also going to Cardiologist next week.
I have a complete right bundle branch block but my 2D echo with doppler results are all normal. What could have caused it?
what is your blood pressure like?
Great video and thanks so much for posting! I'm 58 and had a severe case of Graves Disease when I was 28, that was taken care of but since then I have always had palpitations ever since. I've had some elevated palpitations this past week so I decided to visit a Cardiologist. He discovered a RBBB on the ECG. He said the palpitations were called "PVCs". Could the RBBB be causing these PVCs?...he didn't thing so. He things I may have had this RBBB for a while now but I never knew it. I am on 200mg of Levothyroxine for the thyroid issue (he things that is a very high dose and possibly causing these palpitations and are checking on my TSH numbers this week). Because of this newly discovered RBBB I am now scheduled for a ECHO and Stress Test on the same day in two weeks. Is it safe for me with this newly discovered RBBB to get on a treadmill and get my heart rate pumping that fast??? Thanks!
Thanks for sharing Dan, always difficult to provide individual advice. In general we dont have any major issues with stress tests and right bundle branch blocks, particularly when the stress test is accompanied by an ultrasound of the heart (e.g. stress echo).
@@HeartMatters Thanks for your reply. One other question if I may, is it possible for an EKG/ECG to not show a RBBB at times and then show it again on other readings? I have one of those small hand held testers and at times it says my EKG is normal and then at times it says RBBB. Can it come and go? Thanks again.
@@danc3746 is yours Complete or incomplete? also what is your BP like?
@@tonnny7908 2 years update, I wound up having a double bypass done in August 2023. No more issues with RBBB.
@@danc3746 what is a double bypass?
I'm a 22 year old boy. I got to know that i have LBBB, can you tell me LBBB is curable or it will not go away?
You ok now?
My mom was diagnosed with RBBB and lately her bp has been out of control, can that be a serious problem?
I been looking into it I feel like maybe she already had high blood pressure which caused the rbbb
Where is all this coming from? I just got diagnosed by accident as well, I see allll these responses and it doesn't add up, my father had issues but his 1st heart attack wasn't until he was 79, but look at the rest of us? Ive had COVID 2wice.....is this the result?
Can this condition of a right branch bundle block, happen as a result of takotsubo cardiomyopathy?
Takotsubo cardiomyopathy can have an effect on the electrical wiring of the heart including left and right bundle branch block. It is always important however to look for other cases too before putting it down to the cardiomyopathy. Thank you for supporting the channel Youssab.
I was diagnosed with right bundle branch block I had visit with specialist after having heart sonogram and he says is nothing serious, but to make sure he ordered me to have some others test for vain calcification and also a blood test called apple b not sure.
the test you are referring to is likely an Apolipoprotein (a). We have recently had a video on this you may find useful!
What does it mean if this is coupled with palpitations?
You are probably referring to a couplet? This is a common observation when 2 extra heart beats (ectopic beats) occur one after the other. This is an excellent suggestion for a future video!
Had an EKG done today for work and my Dr. told me it showed I have an incomplete left bundle branch block and he’s going to refer me to a cardiologist. I just turned 30 and I’m freaking out I have no symptoms. He told me it could potentially be nothing since I’m young and have no family history of heart disease but please respond to me :(
@@epiphanyknows9308 I didn’t go to a cardiologist but I spoke with a family friend who’s an MD with decades of experience for a second opinion about what the NP who spoke to me about my EKG results told me. The MD told me that recent literature shows that an Incomplete Bundle Branch Block, left or right, is not significant and is just a common abnormality in the heart that is nothing to worry about as long as it isn’t presenting any symptoms. I do not have any symptoms and my cholesterol levels and bloodwork results were all in the low-normal range so he told me that he disagrees with the nurse practitioner and does not recommend seeing a cardiologist at this time.
@@epiphanyknows9308 I am vaccinated and boosted, never knew I ever had Covid until this same Drs appointment when the NP told me I had Covid antibodies in my blood. I also had thoughts regarding if it could be related to Covid or the vaccine/booster I received since I never had this issue before. From what I’ve read online an incomplete right bundle branch block can potentially be revered through conditioning, and a complete left bundle branch block is not reversible, but there is very limited information on an INCOMPLETE left bundle branch block including whether it can be reversed or not. The NP did check “yes” for heart disease on my job physical form under “past medical history” which was shocking to me since I’ve never been diagnosed with heart disease! My MD told me that the NP shouldn’t have selected yes without me seeing a specialist like a cardiologist and an EKG is more of a screening tool and isn’t used to diagnose without further tests. He said he would have put “no” for heart disease if it were him. Regardless I’m not seeing this NP anymore and will be switching back to my regular MD because he made me feel like crap about my EKG.
I'm 43 just diagnosed with right bundle block. I'm very scared.
As mentioned, always best to check things out with your local doctor, right bundle branch block is commonly seen in young people and often does not signify anything major.
Can a hiatal hernia cause this kind of heart pressure?
Hiatus hernia can caused many symptoms, especially if large. They will not however usually cause any changes to the patterns of electrical signals of the heart. Thanks for supporting the channel!
Right Bundle Branch Block it is a serious? Please answer
As mentioned, right bundle branch block is frequently seen and most often does not indicate anything too concerning. Always worth checking things out with your local MD as well who would better know your history. Thanks for supporting the channel.
I had an ekg the other day and they told me it came back normal nonproblems ...I looked at my portal? I see the bundle branch trying an I was like wow ..but turns out it's not the end of the world
What are they blocked with?
good question, I will run a short video on this as many people get this concept confused. When we talk about blockages we usually talk about those building up as result of plaque inside the arteries. When we refer to block in the wiring of the heart e.g. left bundle branch block it involves the wiring often not functioning correctly and therefore not allowing 'electrical signals' to pass through the tissue.
Why would i want to hear this loud exciting music if i have a bundle blockage or worried for a family member. This is so annoying.
Oh and my CAC score was fine.......WTH is going on????
