Hi there im 46 and last year I was diagnosed with lbbb it kinda shocked me as came as a surprise the cardiologist didn’t really tell me much about the condition so has left me worrying every day 😔has anybody else been diagnosed with it that could explain better what it is and how and if it effects your life
Look forward to hearing from someone 😊
Hello 
I imagine it would come as a shock I think for most of us when we get told we have something wrong with our hearts this is the first reaction then left with fear
I don't have what you have others on here that have when they see your post will answer that do but getting some explanation is what we need it can help so much
The BHF Nurses are really good and I know have helped so many on here it could help to give them a ring
Let us know how you get on x

I was found to have LBBB during the routine tests before getting a knee replacement in 2017. It didn't affect anything around that procedure, or anything else, I even forgot about it for a few years. Then starting in 2022 I began to have occasional faint spells. They got gradually worse until I was given a pacemaker a few months ago due to heart block. I understand that people diagnosed with LBBB may have an increased risk of developing heart block, but it’s not a certainty. Good luck!
I have a left bundle branch block. Firstly, you’ll be ok. Know and understand that. It’s NOT a death sentence but it can be significant for some people.
So you understand better I’ll explain it a little. Your heart beat usually goes boom-boom, boom-boom. The first part of your heart beat (the first boom) is the atria contracting. The atria is the top of the heart. The beat travels from here down through a central branch to the ventricles where it splits off at the same time and travels along the branches to the left and right ventricle. They then beat in unison (the second boom).
In a bundle branch block the beat signal is blocked on one side so the beat has to travel through one ventricle side to the other. This causes a slight delay in one side. I guess you could say your heart beat is boom-bo om, boom-bo om.
You can have either a partial block which is where the beat still gets through but some of the branch is blocked, or a complete block.
A left bundle branch typically causes breathlessness and can cause cardiomyopathy with the extra stress it places on the heart.
Do you know do yours is there all the time or only when the heart is put under pressure? For most people it is only when they’re increasing their heart rate during exercise and similar. People can live a normal life expectancy with a lbbb. If it causes issues and is significant, they will insert a biventricular pacemaker to keep the ventricles beating in sync. I am yet to get a pacemaker but I suspect it will be soon.
Hi Ennasti, re: your reply to GABY007XX, I found your info beneficial. In 2022 I was diagnosed LBBB, LV impairment and EF 25%, but this was not fully explained. A pacemaker implant was attempted but the procedure failed when my heart was pierced with the third lead and emergency OHS was performed to remove the lead and repair the hole. I won't try again for a PM but I am on great meds and keep active. I feel really well but get tired and breathless sometimes. Again, thanks for info. Take care.
Great explanation of Lub and dub, the terms HC professionals use to describe the the mechanical sounds and transition through the heart as the electronic depolarisation and Re polarisation of the impulses occur. In essence, LBBBi s a blockage of the impulse towards the end of the depolarisation after the bundle of His- hence bundle branch block. Usually indicative of a cardiac event such as a heart attack at some stage.
I got diagnosed with it, unbeknown to me prior to my admission for arrhythmia. I had a full life exercising at least 4 times a week, spin classes and sprints on treadmill. I am on beta blockers to control my arrhythmia and struggle when I exert myself too much.
Hope you recover and the cardiologist explains properly the implications and ongoing care. Good luck!
Yes I was. I am 67 and it doesn't really affect my life at all much. However I was lucky there was no underlying reason for it, no heart disease. I think I may well have had it for decades as have always had palpitations/odd beats, especially when under stress or too much coffee. So I just thought it was normal for me. My LBBB is not a problem at the moment as my heart is in good health for my age although I will be monitored going forward. It is an electrical fault if you will, and my heart is dealing with it adequately so no meds required. However it is different for different people and it needs investigating. I think you need to push for more information from your cardiologist about your condition.
Hi Gaby. I had ecg a few weeks ago and have a blockage on the left side and atrial fibrillation. Have an appointment with cardiologist at the end of this month.
They found my LBBB when I was admitted into hospital for CHF and was told that my heart couldnt get stronger because of the LBBB. Not sure if the LBBB came before the HF or after, but was advised to have a CRT-D inplant [3 wire pacemaker] to get my heart beating in sync. Within 5 months the LBBB was gone and I was out of HF, and just had my 1st battery change this past November with no sign of the LBBB. I know the LBBB is a electricle problem, but not much more than that. I have read other posts of people having LBBB and not being in HF, but talk to your Dr. so they can explain what it is and how it can effect you. Take care
Hi I had a RBBB in my 40s , 2 years ago in 2022 at the age of 74 I had slight heart attack and developed another block for which they put a pacemaker in just in case. Which has been ok , I am told i am using it 1% so it's there in emergency. So try not to worry. I was told at the time loads of people live with heart blocks. I have a feeling that the covid vacine was to blame I have no proof but it was shortly after . Good luck
