How do beta blockers help arrhythmias
This is following on from my other recent post... Today I was also offered a beta blocker to try for "palpatations" as the cardiologist called them. I have been getting a lot of ectopic beats (mostly single ones) but had what seemed like a run of them nearly two weeks ago which was disconcerting. I wondered how beta blockers help various arrhythmias?
I remember as a teenager my vasovagal syncope was incorrectly disgnosed as "panic attacks" because "I couldn't breathe" (before fainting) as I told the GP. I now know this was my heart slowing down (which it used to do for a significant while before pausing). I was given beta blockers. These made me pass out. I obviously now have a bad association with the words beta blockers and the GP that incorrectly diagnosed panic attacks and not syncope. In my mind today, I shut down this idea and declined the offer for now, but wondered if I should consider this and how they might help?
I know the same can't happen again as my PM won't let my heart slow down below 40 bpm. Another consideration is that I can always feel when I’m paced which I absolutely detest the feeling.
Regardelss of my future decision, I would love to know how beta blockers help different arrhythmias...?
