The day they put me on minimum dose Bisoprolol I described feeling like a drunk zombie who could no longer feel my lungs working, breathlessness, had to consciously remember to breathe, turned me into an old man overnight.
So I used to cut the tablets in half, none-the less, after three months I was found hardly conscious, and with a heart beat of 42bpm after being brought round with oxygen.
This was last March I came off them.
The symptoms remain and are in fact getting worst to the day.
The NHS refused to believe their drugs could still affect me and so fobbed me off with "its Anxiety".
Its only December I finally got one of my cardiologists to listen to reason, namely, that Beta Blockers disrupt your Autonomic Nervous System by blocking receptors in it.
Every single one of my now mulitiple symptoms is a symptom of Autonomic disfunction, I was able to show them a statement from a medical equipment manufacturing company for the testing of Autonomic Neuropathy that one of the things that can cause it is "Drugs that increase sympathetic activity (sympathomimetics): amphetamines, monoamine oxidase inhibitors (antidepressants), beta adrenergic stimulants
Drugs that decrease sympathetic activity (sympatholytics): alpha and beta blockers (i.e. metoprolol), barbiturates, anesthetics"
I was also able to show that despite lung function tests showing my lungs to be mechanically fine, Autonomic receptors were not responding to low blood oxygen levels in my blood, hence the breathlessness. (See image below, blood oxygen should be between 95 and 100%, the red line I am pretty much constantly below, is considered to be a 15 minute response time medical emergency, they couldn't explain how their "anxiety" could cause that).
I am now being referred to a Neurologist but all my research indicates Autonomic Dysfunction is incurable, I consider Bisoprolol responsible for the forthcoming loss of my occupation, and a remaining life with half my days spent in bed to recover from the previous days exhaustion.
