    Re: what do low b/p people take for tachy?

    I haven't been put on a beta blocker - yet. I'm sure I'll end up on one eventually.

    So far I only take midodrine. It is a vasoconstrictor that increases blood pressure thus helping lower heart rate. It does an ok job at that but nothing outstanding and I still have tachycardia - but 120 bpm or less standing is better then 144+.
    Many with autonomic issues take midodrine with a beta blocker, with success, though I've heard that it seems to bug pharmacists. lol

    Has your doctor mentioned fludrocortisone (Florinef) to you? If low blood volume is one of your issues this would help your kidneys hold onto fluids and increase you blood volume - and blood pressure. And do you know exactly what is causing the tach? If it's directly linked to the low blood pressure it makes sense to help correct that.

    Flecainide, sotalol, or rythmol are also other drugs you might inquire about.

    Re: what do low b/p people take for tachy?

    Hmm, I had never heard of flecainide or rythmol being used before - at least not in people with really low blood pressure.

    What I've seen is atenolol, metoprolol, and bisoprolol - β1 selectives, and propranolol, pindolol - non selectives, and probably a couple others I'm forgetting.
    Though this is in people with dysautonomia where a good portion of us have very low blood pressure, very low blood volume, and sinus tachycardia. And the beta blockers are used to keep the heart rate down because it can trip up the autonomic nervous system and make some of us faint, or we just feel horrible with the excessive tach. (some people have excess of 200+bpm )

    In a few, the beta blockers can raise blood pressure. Though not hugely. It does make the heart contract more strongly and when it's not beating at 140 or so it is more efficient, so to an extent it makes sense in that way.

    What I said still applies though. Get the blood pressure up a little and see if that helps the tachycardia at all.

    Re: what do low b/p people take for tachy?

    Having autonomic dysfunction is seperate from just regular tachycardia like Hope has. She just hasnt been able to tolerate beta blockers because they drop her BP too much. Not all tachycardia patients have autonomic dysfunction. I was first treated with flecainide and rythmol because they are antiarrhythmics and can help with atrial tachs and SVT. I wasnt diagnosed with autonomic dysfunction until after my ablation attempts failed. I am on midodrine, flecainide, and toprol. We tried stopping the flecainide and I had such horrible tachycardia I had to be put in the ICU. So sometimes antiarrhythmics can help with bad tachycardia, especially when you cant take enough beta blocker because of the effect on blood pressure.

    Blood diverts to the digestive tract when you eat, to help you digest. This leaves less for elsewhere. Also, for some, eating can irritate the vagus nerve - this is why people with GERD can get tachycardia and palpitations.

    Has your doctor ever mentioned that you might have low blood volume? If you've said so elsewhere, I've forgotten sorry.

    Re: what do low b/p people take for tachy?

    The xanax could be lowering your blood pressure more. As I've said, try to look for a cause instead of just taking something to lower you heart rate. That you're skinny, under weight even, does suggest that your blood volume would be low as well. If your tachycardia is a side effect of the low BP and low volume, then taking away your body's way of correcting it could possibly make you faint or just feel awful.

    If you have problems with dizziness or lightheadedness, or feel like you are about to faint you may consider asking your doctor for a tilt table test and a holter monitor.
