Nuclear stress test heart rate

Common Questions and Answers about Nuclear stress test heart rate


Avatar_n_tn However my true maximum heart rate was much higher and thus cutting off the test at 85% or 90% of my true maximum heart rate did not allow me to reach a point of exertion where the ischemia showed up on the profusion test. Many instructions for the profusion testing call for allowing the patient to exercise to a level of perceived exertion that is often far higher than the calculated percentage of maximum heart rate.
Avatar_n_tn I have a few questions for y'all 1) What does a nuclear stress test do? What will i be doing? 2) What does this test show? 3) What does an abnormal ett indicate? What does the new findings on ekg indicate? 4) Why would my heart rate be so high? 5) Why do i have to cut out all caffeine? 6) Will they still find anything on the nuclear stress test if i am on new beta blockers? Those are a few questions i have that i never got around to asking my doctor before i left.
214864_tn?1229718839 I had my first non-nuclear stress test this past Wednesday, and I could not reach my target heart rate. I have had 6 or 7 nuke stress test and finished all of them. This Tuesday I am to go back and will have the drug adenosine, or dobutamine to reach my target heart rate. I wasn't told which drug I would have.
Avatar_f_tn I have been experiencing angina for the past several months and I recently took a nuclear stress test. I can not see the cardiologist until next week so I am hoping you can shed some light on my diagnosis. " The patient reached a maximal heart rate of 154, which is 91% of predicted maximum. There is some thinning of the myocardium near the apex with small area of reversible activity in anteroseptal region.
253496_tn?1235231285 I've had humpteen and as long as you don't take a beta blocker the night before, all will be well. My former stupid cardiologist had to clear me for sinus surgery. I had no idey it would involve a stress test. He said "can you take the stress test today?" I says sure why not. I forgot that you always skip your dose of a bb the night before a stress test, but the **&^%% doctor should not have.
Avatar_f_tn EKG in ER was normal, chest xray normal, cardiac enzymes neg. Referred to us for a nuclear stress test and the patient was put on atenolol, ranexa, and imdur. However, non compliant with the imdur because of headaches. A 2 day protocol was used. The patient walked 11 minutes and reached 13.4 mets. 95% to his target heart rate. The patient was short of breath and had chest pain. The Ekg did not really show anything significant.
Avatar_m_tn I've had three over the last 6 years, and one a few years before that when the test was called a thallium stress is nuclear too, but it seems thallium is no longer used. I have no known side-effects and I have gotten two false positives. The latest one that gave this was about 2 years ago, and so I underwent a catheter study and there were no blocks. I think the bottom line is, if the nuclear stress test says you do not have blockage, you most likely don't.
Avatar_n_tn Hi! I just had a nuclear stress test done. It took almost four hours. When you first go in they have to inject a dye into an IV. It takes about an hour for it to reach your heart. So you have to wait for that. Then they put you on a table and have a machine circle around you taking pictures of your heart. After that you do the treadmill part and when you reach your target heart rate they again inject the dye into you.
Avatar_f_tn I am scheduled for my nuclear stress test Nov 11. Ech on Nov 8th. Will either of these tests show if I have peripheral artery disease. I have constant squeezing (feels like blood pressure cuff) with numb tingeling fingers in left arm. Also my legs hurt all the time, sometimes major cramping in my calves. And yesterday groin pain affecting walking all day. (I am female.
Avatar_m_tn Hi all, This question comes from curiosity after reading a post on the doctor's forum by a woman whose husband had a heart attack a short time after a negative nuclear stress test. The doc responded that the test is very good for detecting blockages that are preventing blood flow, but not an indicator for possible ruptures that might occur? I might be remembering that wrong. At any rate, what is the best course of action to take?
Avatar_f_tn The cardiologist put me on a 24 hour portable EKG machine to monitor the palpitations and prescribed a Echocardiogram and Nuclear Stress Test to be done the same week. I got both of them done last week. He said the echo looked fine, but the EKG under stress was abnormal. The pictures taken after the treadmill walk apparently also showed that some part (about 10%) of my heart was not receiving enough blood.
Avatar_f_tn Iv taken a few Nuclear stress tests - in the past I can remember you cant eat anything or drink but water - I was also taken off my meds for 24 hrs before the test . It might be good to call the appointment center or doctors office and tell them - if im not too late at this ! pretty sure it will mess up your test. though some scan tests you can eat peanut butter ? guess it makes the dye show up better in the vains ? I never liked these tests ! as dyes in vains - so on..
Avatar_n_tn Exaggeration of j-point depression at peak exercise. 90% age-predicted max heart rate for pressure rate product 300, met capacity of 10.0 @ l minute following exer. protocol. Post heart rate response of 127 represents 23 point drop in peak rate. On the nuclear part, no reversible ischemia. Inferior wall fixed defect. Left ventricular ejection fraction calculated at 57%.
Avatar_m_tn Maximal heart rate during stress was 152bpm (93% of maximal predicted heart rate). The maximal predicted heart rate was 163bpm.The target heart rate was achieved. The heart rate response to stress is normal. There is a normal resting blood pressure with an appropriate response to stress. The rate-pressure product for the peak heart rate and blood pressure was 25536mm Hg/min. Functional capacity is above normal (greater than 20%).
Avatar_m_tn Personally I really have no fait in the tredmill test. The real way to see your heart is the nuclear test. I passed the treadmill enerything was fine after the nuclear test they found I had had a heart attack. The chemical test is the same as the tredmill.
Avatar_f_tn I had a stress test done last year and you must close to me in age because our target HR's are close. I'm interested to see what your response will be because I've been told & read 2 different things. My BP went from 130/70 - 150/90; and hr from 74 - 154 in 4:55 and my doctor told me that was fine and nothing to be concerned about, what did your doctor say?
Avatar_m_tn I have no symptoms of heart problems, but I have a family history of heart disease. Is a nuclear stress test advisable or is there another test that would be more appropriate given the fact that I'm asymptomatic. I understand that the radiation exposure in a nuclear stress test is 250 times that of a chest xray. I'm concerned about the risk of exposure to that level of radiation given the fact that I have no signs of heart problems at this point.
Avatar_f_tn I had a stress test recently, got through the stressful part just fine but had tons of PVC's afterwards. The nurse/tech, whatever she was, mentioned it and had a frown on her face. I told her it was normal for me and she settled down. My final report: I passed the test and I'm fine. Then again, mine was a treadmill test and most of my PVC's came after they had me lie down. Still, I understand most PVC's are of no consequence.
Avatar_f_tn Hi, If a patient is capable of achieving the target heart rate during exercise and if good-quality images are obtained, a nuclear stress test can accurately diagnose a serious disease in approximately 85% of patients with coronary artery disease. However, in 10-15 % of patients, a false positive test may occur. However, there are other stress tests like a stress ECG or a stress echo which can help in confirmation or ruling out the presence of coronary artery disease. I sincerely hope that helps.
Avatar_m_tn In October I had a follow-up nuclear stress test (Stress QGS Tetrofosmin). I would like help interpreting the results of the test. The report reads: “The post Stress Myoview images show a small to moderate territory of decreased perfusion. This involves the basal and mid inferolateral region and is moderate in severity. The remaining segments are perfused normally.
Avatar_n_tn I had a nuclear stress test. Before the stress part of the test my blood pressure was 213. The Dr said to go ahead with the test. During the test, I got cold and white, was unable to function well, semi unconsciousness, tremors particularly on the right arm, speech slurred, headache in the temple and forehead, fatigue. After many attempts to clear me from these side effects, they gave me a the antidote to the medication that they used. Did I have a heart attack?
Avatar_m_tn I then had an echo done and it was discovered that I had mitral valve prolapse, but normal blood flow. A stress test was ordered (abnormal) and then a nuclear stress was ordered (also abnormal) and there was evidence of a "mild to moderate" blockage. My doctor recommended that I have an angiogram done. Here's what I'm struggling with.
213398_tn?1202674074 been complaining of chest discomfort for months now. had a stress test a year ago and told it was good. just did a nuclear stress test today. my question. i reached my target heart rate of 156 within minutes by fast walking. a year ago my target was reached while jogging on the treadmill. shoild i be concerned ? does this mean i have some heart of vascular problem if i reached the target by fast walking rather then running? i am not physically active in general .
Avatar_n_tn Typically, ischemia doesn't occur at normal heart rates in most people because at rest, with a normal heart rate, the heart muscle's need for blood is small, and the amount of blockage of the coronary arteries is not significant enough to reduce the flow of blood to the heart muscle. During stress, however, when the heart rate speeds up, and the heart has to work harder, the heart muscle requires a great deal of extra blood to generate the energy needed to perform the extra work.
Avatar_n_tn 1. Catheterization 2. Nuclear stress test 3. Do nothing but monitor What would you do? Thank you so much!
Avatar_n_tn A normal nuclear stress test will not show blood flow through the carotid arteries of the neck. In general, a nuclear stress test accuracy rate is 85% to 90% for CAD in your heart. For the carotid arteries, the first test is usually an ultrasound, then an MRI or CT scan and the final test would be an angiogram.
Avatar_n_tn Some rheumatologist at the hospital recommended I have a nuclear stress test before the surgery. I asked her why. She said my age, my diabetes and something else. Maybe family history. My father and his brother had heart trouble at a young age. I went to a cardiologist and he thought it was a good idea. I really do not want to have this test. Do I need it? I know it is precautionary but is it really necessary?
