Thallium dipyridamole stress test with the radioactive chemical given is it true that it is dangerous to be near babies and children after procedure?

Thallium dipyridamole stress test with the radioactive chemical given is it true that it is dangerous to be near babies and children after procedure?

No: The amount of thallium given during a stress test is between 20 and 30 times less than the level where you are releasing enough radiation to be of concern. The half life of thallium is short. To be extra careful i wouldn't be worried after 24 hrs at most. ...Read more

Stress (Definition)

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

Could a 91 year old women have a chemical stress test?

Depends: Depends on what the co morbidities of the patient are and if she has a complicated cardiac history. She can have chemical stress test if she has positive risk factors and signs for cardiac disease. ...Read more

Are there any dangers of getting a 'stress test' at the cardiologist?

Are there any dangers of getting a 'stress test' at the cardiologist?

All tests have risk: While a properly supervised stress test is very safe, the inherent risks of the population of people being tested mean that you will eventually run into problems occasionally. These problems can include arrhythmia, chest pain, heart attack and death. Fortunately these are all rare. ...Read more

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

You : You will be sufficiently radioactive to set off alarms at airports, ferry terminals, and border crossings. The sensitivity of these devices is high on purpose. However, the amount of radiation a patient emits after a cardiac nuclear scan is not considered dangerous to others. Notice that the technologists who perform these tests do not wear lead or other radiation protection and they are around "radioactive" patients every day. For the sake of completeness, however, i will add that pregnant women should not undergo this test and anyone who thinks they might be pregnant should have a pregnancy test before having any kind of radionuclide scan. ...Read more

What BP levels could be dangerous and dissection my aorta? Short term? I got up to 190 in a stress test. Max HR were 196

What BP levels could be dangerous and dissection my aorta? Short term? I got up to 190 in a stress test. Max HR were 196

Normal: That's a normal BP for a stress test. Also, at 23, your maximum predicted HR is 197, so you were at 99% of your MPHR-that's good! There is no BP that will predictably cause an aortic dissection. If your aorta is severely dilated or you have Marfan's Syndrome, it can dissect with a normal BP. BP >240 systolic or >130 diastolic is generally considered to be elevated sufficiently to cause adverse sx. ...Read more

I have pvcs when I am relaxing, exercising and even post exercise. I had a stress test(came out perfectly normal) but i still get pvcs? Dangerous?

I have pvcs when I am relaxing, exercising and even post exercise. I had a stress test(came out perfectly normal) but i still get pvcs? Dangerous?

Unlikely. Unstress!: In someone of your age it is unlikely to be of clinical importance. Often psychological stress may be a factor. Keep track of the frequency (pvc's per 5 minutes) and see if periods of anxiety, anger, fear, or depression correlate with higher frequency. Learn deep relaxation/meditative skills (see drmiller.Com), stay in good aerobic cardiorespiratory shape, and stop worrying. ...Read more

I have 100atrial extrasy everyday, pr -90ms, incomplete rbbb, echo ok, stress test st/v5-1.3, st/ii-2.6 with a few extra. Is short pr interval dangerous?

Usually Not: There are two common causes of short pr, assuming you've excluded machine error (the #1 cause). 1) enhanced conduction from top to bottom. Not a problem here. 2) an "accessory pathway" short circuiting from top to bottom and bypassing normal wiring. These pathways are associated with wolff parkinson white syndrome. You probably don't have this, but i'd need to see an ekg to say for sure. ...Read more

I had a chemical stress test this afternoon. My heart is racing still and I am very flushed. Is that normal?

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

Is it possible for someone with vulnerable (soft) plaques to have a negative treadmill stress test, but still be in danger?

Is it possible for someone with vulnerable (soft) plaques to have a negative treadmill stress test, but still be in danger?

Yes: It's entirely possible - this is, in fact,the explanation for how someone can have a normal stress test and then have a heart attack hours, days, or weeks later: presumably there is no serious blockage at the moment of the stress test, but they rupture a plaque and occlude the vessel at a later time. This is a sad reality. We have no "crystal balls" to predict the future. ...Read more

Can a nuclear stress test be dangerous if I haven't eaten for like a week? I'm afraid I won't be able to do the treadmill because of weakness.

Can a nuclear stress test be dangerous if I haven't eaten for like a week? I'm afraid I won't be able to do the treadmill because of weakness.

Nuclear stress: The risk from a stress test is very low in most patients. In those with certain conditions (like a recent large heart attack, or severe aortic valve disease) the risk may be higher. There is also risk associated with the radiation exposure in a nuclear stress test. It would be very unusual for a 29 year old patient to need a nuclear stress test. Consider a cardiology consult on HealthTap. ...Read more

Mild reversible myocardial ischaemia involving basal segments of inferior and inferolateral walls its dangerous conclusion of stress test or good ?

Mild reversible myocardial ischaemia involving basal segments of inferior and inferolateral walls its dangerous conclusion of stress test or good ?

It is not: normal, reversible ischemia means that there are areas of your heart that do not get enough blood flow under stress, but do get enough flow at rest. You need to see a cardiologist for further evaluation/treatment. ...Read more

Hello, Are heart flutters during very strenuous exercise dangerous? I've been checked out by a cardio but no stress test before. Thx

Hello,

Are heart flutters during very strenuous exercise dangerous? I've been checked out by a cardio but no stress test before. Thx

Perhaps...: Feeling your heart beat fast during exercise is normal, but the term "flutters" would imply some abnormality. A stress echocardiogram will help clear up what's going on with your heart during exercise, and could be helpful if you're embarking on an intensive exercise program. ...Read more

Stress Test (Definition)

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
