Bifascicular block
After requesting my health information and reading through it I noticed an ECG from April last year when I went to the ER due to being short of breath. It said abnormal ECG. It mentioned normal sinus rhythm but an RBBB and a LAFB. A bifascicular block. Now nobody ever explained anything about this to me. So I have been reading up on it the best I can. I am not worried but more surprised that nobody mentioned it to me or explained what was going on. There was no follow up. So I am not sure if I should arrange one. I don’t have a family doctor. I would have to arrange it through virtual care and the wait lists for specialists are very long. How do I know if things get worse? Should it be checked again?

Hi, and welcome to the Heart Arrhythmia 'Club.' Mine is AF, atrial fibrillation.
I would put some serious money on your having found and digested this one site already:
https://litfl.com/bifascicular-block-ecg-library/
Like many arrhythmias, they signify underlying pathology, usually....and they tend to want to progress as time goes on. The citation above suggests that, if you are not currently experiencing syncope that your 'expected' progression is about 1-2% a year towards full block, at which you would have wanted to be fitted for a pacemaker....I think (I'm not medically trained at all...). Those currently experiencing syncope should expect a much heftier slide toward full BBB, at about 12-15% per annum. So, if I understand it all, you are not so badly off, but I would think you should have been apprised, ethically, and told about how to begin to educate yourself of potential degradation of your heart function and what you/they can do. Ethically, I would have felt this to be the case. However, I only learned that I am borderline on kidney function in terms of being high/out of range on creatinine. I queried my GP who replied that it had stopped changing over a decade ago so they just put me on a watch status. I haven't had a blood test in three years, so I guess I need to rattle his chain.
I hope you get lots of dialog here from others who share your disorder.
I've known of bifascicular block for 9 years (now 72) facing removal of both kidneys (advanced ADPKD).
Cardiologist did 10 day monitor; says as long as no fainting: nought to worry. Have read it's a function of aging in some.
