The people likely to see your question are highly unlikely to have the expertise, or the data about your husband, to make an informed reply to you, including me. Some might reply about a similar experience, but the actual treatment and any further diagnostics are going to be up to the team currently monitoring your husband.
What I mean by my response just now is that your husband's heart 'sounds like' it is highly disordered, but that's just to me, someone who has no experience or expertise. I wouldn't be surprised, though, to learn that the easiest remedy works quickly and amazingly well. For example, a pacemaker might be the simplest answer, and he could have one installed tomorrow....literally...if the people looking after him understand what is going on and that a pacemaker is highly likely to be the saving grace here.
Please be patient...you might get much better answers. I know you are anxious (who wouldn't be?!?), but the details seem to be fairly well known as you report them, so someone with a bright bulb between his/her ears is working on this close to where your husband is.
Good luck!

@gram0322, You are getting good advice on what to do. We are not experts or medical professionals on MCC. Very hard to even give advice when you don't know medical history.
I can give my experience though. Has your husband had a echogram to test EF? Has he seen a EP? From what you are posting he should be seeing a EP (electrophysiologist). I see both a EP and HF doctors at Mayo Jacksonville.
When your EF gets low your heart is not pumping enough blood into body. Not everyone is the same though. What I had was problems with electrical system and getting tachacardia and tons of PVCs. The standard per EP is when your EF gets around 30 they suggest a ICD/Pacemaker.
I am on my 3rd one. I have had one since 2006 and probably about 10 shocks in those 20 years. Without it though I would not be typing this. With medications, and fine tuning my pacemaker my shocks have been very rare now compared to a decade ago. I am on some great medications that help prevent tachacaria and PVCS.
The tachacardia can put you unconscious as heart can go into VFIB and you will faint and go unconscious. So when this happened in past my ICD/Paceamaker sees it and shock my heart back to rmypthm.
It is why I asked since you mentioned several bundle branch blocks (which are all electrical issues of heart) if you husband is seeing a EP. If not would suggest he see one and try to go to a major medical facility to do that.
Good luck!
