    Revs up the liver (and sometimes also the spleen) to soak up most if not all the thallium. You end up with a
    liver/spleen scan rather than a heart scan.

    OK fellas - went for the test today.

    Surprise No.1 - Appointment met on time ;-)

    Surprise No. 2 - No exercise required.

    Surprise No.3 - A seriously [censored] IV something-or-other that made me feel
    like I was signing off (sudden breathlessness/chest pains/dizziness/syncope)
    which lasted for exactly 6 minutes, at the end of which the thallium was
    injected and the pictures taken. If they'd given me a choice between this
    and 20 mins on a treadmill the treadmill would have won hands down.

    PS the reason for no caffeine is something to do with caffeine supressing
    the receptors that make the [censored] IV feel like you're checking out.

    Apart from that a GREAT DAY!!!!!!

    Glad it went OK. From what you describe I think I've had the type of test you
    describe and also the exercise type. If you had the exercise type, I'm not
    sure you would prefer that. The treadmill goes faster and faster and gets
    steeper and steeper until your heatrate gets to the desired point. For me, it
    usually ends with me saying I don't think I can hang on much longer and a
    nurse pushing on my butt from behind to keep me on. 🙂

    Oh, yes, Bill - I've had two treadmill tests. The before-angioplasty test
    was a lot worse than the after (as you might expect) but both of them were
    preferable to the chemically-induced stress I had yesterday. At least on a
    treadmill you can stop - and at least you have an identifiable reason for
    feeling bad. Sitting doing nothing but suddenly finding you can't get your
    breath and feeling like someone's sitting on your chest whilst at the same
    time fighting hard not to pass out and having a real problem speaking
    coherently was a bit of a surprise to me - although I was warned beforehand.

    Still, it's all over - for now. Have to wait and see what my cardio says
    about the results but I suspect further procedures might be necessary.

    Cheers

    At least they warned you. They never said anything to me prior to the
    injection of the chemical. . I even remarked to them after the test ,
    that a nice touch would have been to give me some warning of what I
    was going to feel. ( And this was a Hospital that does many of these
    test, due to the busy Cardio ward)

    Hi Bob,

    There's absolutely no excuse for that - except, maybe, if they'd told you
    how it really is you'd have probably said no way ;-)

    This is the "rest of the story" , now that you have got me thinking
    about this test. When they rolled me down to the Nuclear medicine
    area, the first person I met who was one of the technicians who
    greeted me . I asked him, " Am I going to do the treadmill or is
    there some other way this test can be done, because they told me up on
    the ward that I probably would not be using the treadmill?" This
    was his reply.... " I have been working here for years and if I was 90
    years old , and using a walker , I would still rather do the
    treadmill than take that horrible drug............"

    I got so freaked out over hearing this that I went to the persons
    supervisor ( At least I figured that's what he was, because his shirt
    was cleaner) and repeated the first person's comment to the
    supervisor. The supervisor said, " Oh don't listen to him, he doesn't
    know what he is talking about, this test is perfectly safe. ".

    Now this sounds like a conversation overheard in the kitchen in a
    McDonalds Restaurant , but in fact this is exactly what took place in
    the Nuclear medicine Lab in one of the best Cardio Hospitals in the
    Southeast .

    Now I am thinking, " I should really get up and out of this wheel
    chair and just leave and go home while I am still able". I finally
    decided to stay, after 2nd and 3rd guessing . Next thing I know they
    shoot me full of this medicine with "no warning or explanation of what
    was about to occur " and I felt like they just injected me with 1/2
    quart of hot DRANO. When I asked the nurse, " Is it normal to feel
    like your chest and abdomen are " On Fire" or am I dying , the nurse
    then told me that this is a side effect of the medication I was
    given. ( Talk about insensitivity, these people were experts at that)

    As they were rolling me back to my room on the Cardio ward, , I was
    thinking that this entire experience that I just went though was about
    as unprofessional as you can get.

    Bob

    They should have given you a better explaination. It sounds like they gave you
    Persantine (Diprydamole). Do you take Coreg or another beta-blocker? If so,
    that is probably why they did not do the treadmill. The idea of the treadmill
    is to get your heartrate up pretty high and beta-blockers tend to lower it -
    so you can't achieve the target. You can go off the drugs for a couple of days
    so you can do the test on the treadmill, but some Drs. don't like to do that.
    Another, obvious, reason to avoid the treadmill is joint problems, etc.

    From what I understand, I think your reaction was fairly common. Mine was a
    little different. It was sort of a great anxiety - almost panic.

    I have had both types. I have always had the treadmill type test and
    kind of looked forward to seeing how long I could go on the treadmill.
    The last time , due to my bad arrhythmias, they gave me the chemical
    to speed up by heart rate ( it is supposed to dialate your arteries
    causing your heart to beat faster to keep your blood pressure up ( I
    think I remembered that correctly). Anyway, I will take the exercise
    method any day. It didn't hurt, but the sensation from the chemical
    wasn't pleasant either.

    Bob

    Just to clarify for you...the medication you had (likely Persantine
    (diprydamole)) does dilate your arteries and your heart usually speeds up a
    bit, but not nearly as much as it would if you were on the treadmill. Also,
    Persantine usually lowers the blood pressure a bit.

    Some people experience a lot of side effects with the medication, and other
    people don't feel a thing.

    In our department, we always try to exercise people on the treadmill if
    possible. But if we think the patient might not get to their target heart
    rate, for whatever reason, we go to the medication. If you try the treadmill
    and don't make it to your target, the results of the test may be considered
    invalid, which would require rebooking and repeating the test using the
    medication.

    They couldn't do the treadmill, which I normally have, because my
    heart rhythm was much too erratic. It was so bad that it was
    difficult for them to get a proper count of my heart rate.
