Should someone with atrial fibrillation have a exercise stress test or a thallium stress test?
If you are a patient currently in atrial fibrillation. Generally speaking an adenosine or lexiscan nuclear stress tests are usually the best options. The other medicated stress test is Dobutamine (both echocardiogram and Nuclear). You do not want to use Dobutamine on patients at risk to go into atrial fibrillation because it is a drug that can induce it. For patients that are in chronic atrial fibrillation dobutamine can be used but is not considered to be as diagnostic as a lexiscan or adenosine stress test. The reason being (and this goes or exercise stress tests as well) dobutamine is a heart rate dependent test. This means the closer the heart rate gets to the patients age predicted max HR the more accurate the test is at detecting Heart disease. The assumption in this is that the patient is in a sinus rhythm. Myocardial oxygen demand correlates directly with patients HR when the patient is in sinus rhythm. If the patient is in atrial fibrillation that correlation with myocardial oxygen demand becomes much more cloudy thus reducing the sensitivity of an exercise or dobutamine stress test with patients in atrial fibrillation. Both lexiscan and adenosine eliminate HR demands in detecting CAD which makes them the best test for a.fib patients.

What characteristics does a normal thallium heart scan have?
A normal thallium heart scan typically shows even distribution of the radioactive tracer throughout the heart muscle, indicating adequate blood flow to all regions of the heart. There should be no areas of reduced blood flow or "cold spots" which could indicate potential blockages or areas of reduced heart muscle function. The scan should also show normal heart wall motion and function.
What are the group 13 elements used for?
Group 13 is referred to as the "Boron Family" (boron, aluminium, gallium, indium, thallium) and its uses varies depending on the specific element. Aluminium is the most widely used of the group. The link below should prove useful:
If someone sprays chemicals?
If someone sprays chemicals, it is important to ensure proper ventilation, wear appropriate protective gear like gloves and a mask, and follow the manufacturer's instructions for safe use. In case of exposure or adverse reactions, seek medical help immediately.
Does Creatine Kinase require fasting?
No, fasting is not required for testing Creatine Kinase levels. However, certain activities such as vigorous exercise should be avoided before the test as they can temporarily elevate CK levels.
Loser means what?
"Loser" generally refers to someone who is defeated or has failed to achieve success in a particular situation or endeavor. It is often used as a derogatory term to belittle or insult someone.
How long should someone exercise each day?
someone should exercise at the least of 30minutes a day. Also it should be a constant work out
How is ventricular fibrillation diagnosed?
When an individual suddenly collapses, the possibility of ventricular fibrillation should be considered immediately.
Would you recommend that someone with asthma exercise regularly?
Yes, they should do exercise regulary.
What care should a patient receive after a thallium heart scan?
The thallium scan is performed in conjunction with an exercise stress test. At the end of the stress test (once the patient has reached the highest level of exercise he or she can comfortably achieve), a small amount of the harmless radioisotope.
Why is 81 the answer to how many protons and neutrons in a thallium atom?
The atomic number of thallium (Tl) is 81, which represents the number of protons in the nucleus. Since thallium is a stable element, the number of protons and neutrons in its nucleus should be equal. Therefore, the number of neutrons in a thallium atom is also 81.
How should one treat ventricular fibrillation (VFib) effectively?
Ventricular fibrillation (VFib) should be treated promptly with defibrillation to restore normal heart rhythm. This involves delivering an electric shock to the heart using a defibrillator. Immediate CPR should also be initiated to help maintain blood flow until medical help arrives. It is important to act quickly to increase the chances of survival for someone experiencing VFib.
If it is close to the time your period starts should you cramp during exercise?
u should tell someone about your fellings!!!!!!!!!!!!! lolololololol
Should patients with atrial fibrillation take Sumatriptan for migraines?
Those who have atrial fibrillation should not be taking the triptan class of medications such as sumatriptan (Imitrex). Any person who has a prior history of heart condition should reconsider taking these drugs, but in clinical trials - the only people who had atrial fibrillation from the medication, were the ones who had a prior history of it. So, taking these medications can trigger this arrhythmia in those who already suffer from it.
What characteristics does a normal thallium heart scan have?
A normal thallium heart scan typically shows even distribution of the radioactive tracer throughout the heart muscle, indicating adequate blood flow to all regions of the heart. There should be no areas of reduced blood flow or "cold spots" which could indicate potential blockages or areas of reduced heart muscle function. The scan should also show normal heart wall motion and function.
Should emergency defibrillators be used on patients suffering atrial fibrillation attacks?
If patients with atrial fibrillation experience rapid heart rate (rapid ventricular response) and are hemodynamically unstable (hypotension, altered mental status) then electrical cardioversion is appropriate. Defibrillation is never utilized in atrial fibrillation.
What is the limt of excerciseing a week?
There is no standard limit to the amount of exercise someone should get each week. Listen to your body to determine if you are getting enough or too much exercise.
What should you do if the heart is fibrillation?
Call 911 and apply an AED to see if the heart can be shocked into normal rhythm.
