Chemically Induced Stress Test
Chemical induced stress test today was horrible. My hands turned blue during test. Why would that happen? Felt like I was dying. Will never do again
Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more

I had a chemical stress test this afternoon. My heart is racing still and I am very flushed. Is that normal?
Not usually: Chemical stress tests w Dobutamine can cause heart racing but the Dobutamine typically wears off quickly. Lexiscan or Adenosine usually slow the heart rate. Let your doctor know. Rarely an arrhythmia like atrial fibrillation can occur w a chemical stress test and persist after, w fast heart rate (irregular) and possibly flushing. ...Read more
Thallium dipyridamole stress test with the radioactive chemical given is it true that it is dangerous to be near babies and children after procedure?
Unlikely: But in theory it is possible, but the effects should be temporary. ...Read more
NO!!!!: Caffeine should not be ingested prior to pharmacologic cardiac stress since it can interfere with the results. Stopping caffeine ingestion for at least 24 hours prior to pharmacologic stress should be sufficient. If caffeine is ingested and pharmacologic stress is performed, this can cause false negative results. If you have taken caffeine, stress may be rescheduled or switched to dobutamine. ...Read more
I had a two day chemical stress test for my heart. Today I have a generalized soreness around my heart. My vital signs are good. Is this normal?
To be "concentrating" on your heart more after such testing!! The test itself did not hurt you since you were monitored before during and after the actual testing!
Hope this is helpful

I am unable to take a stress test while on the treadmill since I have lung and asthma problems. What reactions should I expect from the chemical stress tests?
Depends on lung issu: There are two main types of chemical stress tests: Adenosine and persantine. Adenosine can/and does induce asthma attacks in many asthmatics so make sure the cardiologist knows about your asthma. It can be reversed but they don't like affecting the lungs when posible. Generally what they do is make your heart beat faster and pump harder. So you feel a little jumpy but rarely and specific pain. ...Read more

Target heart rate...: If you are having an exercise stress test, there is a target heart rate which needs to be reached. This target heart rate is 85% of your maximum predicted heart rate. Maximum predicted heart rate is given by equation (220 - age). If you do not reach target heart rate, the exercise test may need to be converted to a pharmacologic stress test. Therefore you have "failed" to exercise adequately. ...Read more
Heart test: A stress test is also known as an "exercise stress test" and it involves you running on a treadmill until we "stress" your heart to it's predicted maximal heart rate (220 minus your age).If you have heart disease we often see changes in the continuous ECG done during the run. ...Read more
Imaging: Heart Imaging tests (nuclear, ultrasound & MRI) are a non-invasive way of evaluating heart function performed in conjunction with physical activity (treadmill or bicycle) or using non physical means (using intravenous medication eg. Dobutamine, lexiscan, adenosine or dipyridamole). All the above provide indirect information on blood flow, presence of scars and the strength of heart contractions ...Read more
Stress test: A stress test for screening purposes usually has no associated pain. Treadmill stress testing can lead to tired legs and shortness of breath. If the stress test has changes suggestive of a blocked artery, and the patient has chest pain or pressure, the tst is stopped and is sent for immediate catherization. Chest pain or pressure suggests heart disease. ...Read more
Baby monitoring: A non-stress test is a way of checking on the baby. We listen to and record the fetal heart for 20-30 minutes. We are looking at the baseline heart rate and how the heart rate goes up or down. We are looking at this to see if the baby is getting enough oxygen or if there are other problems with how the baby is doing. ...Read more
Your heart's OK!: It means you did not show signs of heart trouble with exercise ("stressing the heart"), and is generally a sign that your heart function is normal, which it should be at age 34. ...Read more
"negative" is good: A "negative" stress test means the absence of what is being tested for--i.e. No signs of flow-limiting blockages in coronary arteries. In other words, the heart muscle is getting plenty of blood flow. It's important to note that a normal stress test does not mean the absence of underlying non-obstructive coronary disease. Detecting this may require other tests, depending on your risk profile. ...Read more
A stress test is a cardiac test which can include walking on a treadmill and monitoring your heart while you are walking. They can also inject you with a nuclear material and do a more comprehensive scan on your heart to check for blockage. They can also do a chemical stress test which omits the need to ...Read more
