    I had it chemically induced as well. I forget exactly what it was but is was two chemicals normally in you body. It triggers your fight or flight response so to speak. The technician will recognize the signs before you do and let you know it's about to kick in. Within a couple of minutes they will probably tell you to drink a soda. The caffeine will counteract the chemical and bring you down. About 45 minutes later they will take more photos. Relax, you do just fine.

    I had the same procedure. It wasn't fun, but it wasn't painful. It was just uncomfortable being short of breath for a little bit, maybe a minute or two, then it was over. I took the rest of the day off.

    The risk of you having a heart attack during the procedure is low, but if you do have one, you'll be in the absolute best place you could possibly be.

    Good luck!

    My 92 year old mom was in the hospital with very bad back problems and they wanted to do the chemical stress test because she'd complained of chest pains when the paramedics picked her up, and could not do the treadmill because of her back. She has GERD, which IMO is what caused the chest pains (subsequently they found very bad acid-scaring in her esophagus, and a hiatal hernia), but the cardiologist insisted it was her heart, and wanted to run every test possible. But as mom's advocate I refused the chemical stress test because - especially in elderly - it can cause serious issues (heart attack and sudden death) during and even weeks after the test.

    So they did many other heart tests and found nothing, then a week later her primary doc called and said he'd heard I refused letting her submit to the chemical stress test, and said I'd made the right decision. He'd seen elderly die on the table during it.

    So OP, I know you aren't elderly, but IMHO do the treadmill if at all possible. BTW I'd also talked to the technician who ran the stress tests before refusing it, and he told me that frankly he'd be reticent to let his own mom take the chemical test as well, but wasn't worried about the treadmill test.

    I had my BP go up to 205/115 about 3 months ago- went in to have it checked out. Luckily nothing was found. I went through the stress test, an angiogram and the echo- all clear! (probably due to a steroid med I was taking) The stress test was well managed- no problems at all.

    Been there done that many times..Did the tread mill several times but my legs are not strong enough for that anymore so now it's done with meds..The worst part,for me, is laying there with my arm over my head for 15 or 20 minutes while they run the scan..

    No worries man. My wife is a cardiovascular tech. She said your are constantly being monitored. If your heart beats too fast, they slow it down immediately with an antidote. Good luck to you Tazz!

    The patient before me was explaining it to me....she can't do the treadmill so she gets the meds instead. The doctor is there to make sure everything is ok. They use the meds to stress your heart and the antidote is sitting there waiting to be needed. They are professionals and do this all the time. You're in good hands.

    I use to practice destroying 12 Nike Hercules missiles equipped with W-31 Mod 2 Nuclear warheads in the 1980s. Worked all the stations including cap point. Nothing like trying to crimp 2 blasting caps to a time fuse in freezing cold temps without gloves on. Hands don't work as well. Dropped a few caps the first time. lol

    I had it done recently and it's as the previous posters have said. Not fun but not painful although the dye feels a little weird going in.

    When I had the test they had to use the antidote. I went from severely stressed to perfectly normal in seconds! It was an amazing feeling! I'd say, as long as you're seeing a reputable doc :), go get it done and don't worry about it. They really do know what they're doing and I'm sure you'll be in good hands.

    It sounds like trying to give yourself a stroke to see if you might have a stroke, to me.
    Not understanding the point of that.

    Okay let's get a couple of things straight. There are 4 types of nuclear stress tests. You have nothing to eat or drink several hours before the test. No caffeine products for 12-24 hours before testing depending on type of test.

    All tests begin with baseline images in a nuclear camera to see the heart at rest. An IV is started, and isotope given and you lay in a tube for 18-20 minutes. Then the actual stress part takes place. All patients are hooked to a constant monitored ECG and blood pressure cuff. Doctor/Nurse Practitioner supervises test along with a Nuclear CVT.

    1) Cardiolyte/treadmill nuclear- The patient will exercise on a treadmill and have to achieve 85% of their MPHR (maximum predicted heart rate) based on their age. 220 minus their age is 100%. The treadmill starts out slow and they increase speed and incline until you achieve the rate and then deliver an isotope tracer through an IV while on the treadmill.
    2) Adenosine Nuclear Stress - An infusion for 5-6 minutes of a vasodilator medicine Adenosine to dilate blood carrying vessels. Peak stress is at about 2 minutes into infusion and the tech will infuse the nuclear isotope at this time and allow the infusion to continue. This medication is delivered by volume based on the weight of the patient. It is mixed with normal saline to help the delivery with fluidity. A certain elevated heart rate does not have to be achieved.
    3) Lexiscan Nuclear Stress - Another vasodilator medicine which is one size fits all that is delivered through an IV. Not weight based in volume and a certain heart rate does not have to be achieved. An eligible person may walk 1mph on treadmill and 1:30 into walk the Lexi is delivered through an IV and flushed with normal saline. The patient continues for a minute and then stops. If a patient cannot negotiate a treadmill then they are given squeezie toys or foot and hand exercises to do. When they have done them for about 1:30 the Lexiscan is infused followed by the normal saline flush.
    4) Dobutamine Nuclear stress - For a person not able to treadmill and not able to have the other medications this medication does elevate the heart rate to the 85% of MPHR and then the isotope is infused.

    Each one of these tests has parameters and contraindications. These values are looked at under pre-screening and also doctors preference before one is appropriately ordered.

    After these stress portions are done the patient goes back in the camera for the "after" set of images. The nuclear isotope traces the flow of the blood in the system It is not a dye. Think radioactive here. It isn't a color it is a glow. So when peak dilation occurs under any one of these tests the nuclear traces where the blood flows and stops where the blood doesn't flow and shows restrictions if any. The images are captured in the nuclear camera and before and after images are compared.

    And yes caffeine is an antidote for use after the stress portion. That is why you cannot have it before the testing. I hope this gives you some info on the tests. I'm sure different physicians might alter these procedures but what I have outlined is industry standard.

    Aminophyline is the reversal agent used for nuclear stress patients having symptoms.

    I did the treadmill thing about six weeks ago. I'm 61 and they pushed me to 175 bpm. It just about killed me but I did it. I wasn't going to give up in front of a female doctor and a couple of hot nurses.
