Left bundle branch block

Ah, ye olde age. It hath its charms, but they're fleeting.

I believe the drug you are thinking of is furosemide, which is used to lower blood pressure. I could be wrong, of course, but that's my guess.

Causes of LBBB are:

Sorry you have this new diagnosis. Is the prednisone for your lungs? Do you have symptoms related to the left bundle branch block?

I hope you can get in to a cardiologist quickly and that you are reassured, or treated effectively. Keep us posted!

I was diagnosed with Left Bundle Branch Block (LBBB) at the same time I was diagnosed with atrial fibrillation (Afib) almost eight years ago (at the age of 58). After my diagnosis, I learned that my father also had the same condition. While LBBB isn’t generally considered a heritable disorder, the American Heart Association (AHA) notes that several genetic mutations have been implicated in bundle branch block. So, who knows?

I mention my father because he is 95 years old and in good health, which gives me some hope. I believe that all the medications I’ve been on since (beta blocker, statin, blood thinner, diuretic, and receptor blocker) help manage both Afib and LBBB.

For years, my Afib and LBBB were generally well-controlled—until I finally got COVID. After that, my heart went haywire, and I ended up needing an ablation. Thankfully, since then, I’ve been heart-problem-free for almost 16 months (knocking on wood).

Wishing you good health!

LBBB is not necessarily a bad diagnosis. Many factors affect how this effects heart function. I have had it for ~ 10-12 years. I have had aflutter since rendered gone by an ablation 12 years ago. I just had my 2nd ablation in Sept for Afib and am hoping for the best. I am being treated for 2 tick diseases which complicates my ability to withstand healthy robust physical activity. But that said I get an ECHO every two years as my LBBB has been stable. As of right now I do not need any intervention for it. I do not have high blood pressure nor am I overweight or have diabetes. I have no symptoms from it and I already have what is technically "bradycardia". But I not only inherited my father's low heart rate but I also was very athletic much of my adult life. So my heart beat at 48 bpm feels real good to me. Wait on getting your heart functions tested to understand how this may impact your life. I will be 77 in 2 months and am fighting to get my strength and conditioning back while being treated for babesia and bartonella which affect my life far more that LBBB does.

I was diagnosed with LBBB decades ago. It was found on a stress test for SWAT team. I had a catherization which revealed no cardiovascular disease. From my workup I advised had a virus infection just prior to diagnosis. I was then diagnosed with cardiomyopathy.

The virus had entered my heart and caused scar tissue. That is what LBBB is. The normal electrical path is block. I was told back then that many pilots have it. What you really need to watch and have your medical specialist watch is how the heart reacts to it. Does your BP rise and can cause HF over time, etc.

It is too bad that can't see cardiologist sooner. I can't give any feedback on why you were given prednisone. It sound like something else was noticed but cannot comment on as don't know what all your tests revealed nor a medical professional.

I would push for a earlier appt. and asked them to set up if there is a cancellation and get in sooner. What I found was in my case the anxiety over having to wait and start treatments or what cardiololgist can lead to more stress and worry which can affect your mental and physical health.
Good luck.

Diagnosed 20 years ago with LBBB at age 58, placed on a BP med. 15 years later Afib came along with an ablation and then a diagnosis of sick sinus syndrome and a pacemaker. For me, LBBB was the slow onset of more electrical heart issues. See if the cardiologist will refer you to an EP.
