Re: Vagal vs. Adrenergic afib

[Guest guest]

why are beta blockers bad for vagal afilb? How you do you distinguish between

vagal and adrenergic?

Thanks

Re: PACs and PVCs with aberrant conduction

Hi Sandy,

you may want to discuss with your doc the route I've taken with

beta-blockers

if you've not already tried it.

beta-blockers are just about the only thing that 'control' my rate when I'm

in AF but they were giving me trouble in NSR.

As you no doubt know, beta-blockers are generally not considered a good idea

for people with vagal AF.

Do you know if you PACs/PVCs are really premature or the result of a missed

beat?(If your SA node is firing too slowly this can also induce ectopics)

I probably have vagal AF and the beta blockers were slowing me down too much

when I was in NSR. (day time resting rate around 50bpm). I now only take a

beta-blocker when I go into AF (though it does take around 60 minutes to

kick

in).

My NSR life has seriously improved since it's been med free, a lot less

ectopics and a heart rate appropriate to my work load.

Just a thought Sandy, we are all different.

How you do you distinguish between vagal and adrenergic?

if your A-Fib is normally triggered by exercise, stress, stimulants, exertion,

etc., then you may have " Adrenergically-Mediated " A-Fib. People with Lone A-Fib

seem more prone to Adrenergic A-Fib. But if your A-Fib occurs at night, after a

meal, when resting after exercising, or when you have digestive problems, then

you may have " Vagally-Mediated " A-Fib. People with structural heart disease seem

more prone to Vagal A-Fib. (Many people have a mix of both Adrenergic and Vagal

A-Fib.)

It's important to determine whether you have one or the other so that you

can better identify what triggers your A-Fib, and because the treatments are

often different for each. (Though it's difficult to generalize about A-Fib

treatments, because each person reacts so individually.) For a more in depth

look at Vagal A-Fib, go to http://www.vagalafibportal.fsnet.co.uk.

The above comes from http://www.a-fib.com/FAQs.htm question #22

Where did you get he above information from. I had always undersood it was

the other way around. Thanks

I also had understood that people with structural heart disease are more

likely to have adrenergic afib while vagal afib is caused by vasovagal

stimulation, or irritation of the vagus nerve which controls both digestion

and heartbeat. However, I have had both kinds of afib, although primarily

vagal, and have no structural heart problems or heart disease. Apparently

adrenergic afib is not always accompanied by structural or disease defects,

but heart structure problems or disease can lead to afib.

I also would like to know the source for your information, Steve.

Happy Holidays to everyone!

Dear Fran,

You are absolutely right. Thank you for the correction.
