Blimey Yorks,
It isn't nice is it having these electrical problems.
In some sort of twisted way, sometimes you wish you'd just had a normal, classic, good old fashioned heart attack where they whip you in, insert a stent and send you home with no real after effects.
Having dodgy electrics fixed is right at the edge of what they are currently able to do. If you are lucky they might invite you to have an ablation done to resolve it. This may well sort the AF and is quite successful in doing so. The VT is a bit trickier though, currently there isn't really anything surgical that can be done and it is managed mainly via drugs.
I suffer with VT which can and has deteriorated into VF and mine is managed by a large dose of beta blockers and a drug called Flecainide. Not a nice drug but not as bad as Amio. With me it took them a while through trial and error to get my drugs right but touch wood, I've been good for over a year now, I'm just slow on the bike due to the drugs!
My advice to you is to ask when you can come off the amio, I assume you are on it to quickly calm the ticker down and once it has calmed you may be put on something else? With regard to getting on the trainer, I wouldn't just yet but if you do, go slowly. You are probably better off just going for a walk for the time being. You need to recognise things are different now..... but they may, in time change back for the better.
As for having the ICD, day to day, mine doesn't bother me in the least. Just make sure you keep your arm down for a few weeks but don't be afraid of moving it. It actually mowed the lawn in my first week and that involved starting a petrol mower!
With regard to what the ICD does, most probably with you, all it will do is perform some 'ATP' (anti-tachycardic pacing) this is where it 'overdrives' whatever your heart is doing. If the worse does happen and you find yourself in VF, first of all you will probably be unconscious but if not being shocked is not that bad, don't believe all the nonsense you read about it being horrible, it really isn't and after a zap you will feel much better! Mine has zapped me three times and has done a bit of ATP.
Do you know your ICD settings? Mine is set to....
40bpm is the bradycardic limit, this is where it acts like a normal pacemaker and won't let your rate drop below that threshold. Mine has never done this.
220bpm is the shock threshold on mine. If I get to / past 220bpm, ZAP !
Between the two it'll do ATP.
Anyway....
Please be assured that life does go on, you will get better and please know that you are NOT alone with this, although it may seem like it at times.
