Electrocardiogram Vs Stress Test
Had echocardiogram, nuclear stress test w cardiolite, EKG and 30 day holter. Does the echo and nuclear test rule out CAD or any potential blockages?
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
Checks heart functio: Thallium is a radioactive (minimally) isotope that is used to study the pumping capability of the heart, usually after heart attack or prior to surgery in someone with cardiac disease. Sometimes it's done simply to ensure proper cardiac capability in someone with risk factors or prior heart issues. It involves mild to increasing exercise to "stress" the heart and assess function under effort! ...Read more
Change w/exercise : When excercised, or 'stressed', the heart needs more oxegen to function properly than at rest. If it's not getting that increase, the muscle will start to move in abnormal ways, which will show up on the echo. At rest, because it needs less oxegen, it may be getting enough, so it will look normal then. ...Read moreSee 1 more doctor answer
My stress test results read " positive exercise stress test for ischemia by EKG criteria. What does that mean?
This means that the: EKG portion of your stress test had changes in the waveforms that have been known to be associated with blockages of the coronary arteries. Unfortunately, greater than 15% of the time this is inaccurate in women. Less than 5% of the time in men. This is why we always do stress testing in women along with nuclear imaging. If the nuclear imaging is negative then the EKG changes are FALSE positive. ...Read more
Low vs ?Higher Value: Stress tests only capable of detecting very advanced disease, ?chances of heart attack & do nothing to solve issues (i quit doing these 1995). Angiogram with PTCA option has risks (usually small) but can see problems & offers opportunity to open arteries & decrease symptoms at same time. The bigger issues are optimizing lipoproteins (nmr particle test), hba1c & bp, etc. To ??? disease progression. ...Read moreSee 1 more doctor answer
A screening test: Stress tests are largely done to identify patients at risk for heart attacks. For patients who cannot exercise due to arthritis or other reasons, Dobutamine is a drug that will mimic exercise, and allow a stress test to be done. It is not as good as exercise, but it is a reasonable alternative if exercise is not possible. ...Read more
Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage.Answer depends on information physician needs and insurance. ...Read more
nuclear stress: All tests have sensitivity and specificity and each lab has its own data. In the best labs these values for this test are >85% sens/spec., there are many technical factors. We choose tests by the information needed and the best test o get us what we need to know. ...Read moreSee 2 more doctor answers
Normal D-Dimer lab, cardiac echo shows mild RCA blockage , physican ordered a nuclear stress test . I am a Paramedic ,can you code with a stress test?
Unlikely: The long answer is that you have a stressful job and you are frequently in situations that cause emotional and physical stress. You should be fine. They will be monitoring you during the test. Also, if the test were that risky, we would not do it so often. Even if you do code. You will be on a monitor in a medical facility with the ability to resuscitate. ...Read more
Cardiology: What can an alternative to having a cardiac treadmill or nuclear injection stress test? A calcium score?
Not exactly the same: Different type of stress test are available (ekg treadmill, pharmacological or treatmill echo, pharma or treadmill nuclear). They all try to answer one question: are there blockages in the artery of the heart that cause insufficient blood supply to the heart under stress? Calcium score tells you what is the burden of atherosclerosis (the disease that causes blockages in the artery) in your artery. ...Read moreSee 2 more doctor answers
Is nuclear stress testing or echo more accurate for calculating ejection fraction? Nuclear says 67 percent echo says 48.
Yes...: Yes...Nuclear stress tests can have false positive results. There are different types of nuclear stress tests. There is treadmill vs. Pharmacologic and there is spect vs. Pet. There are also many different tracers such as thallium or technetium for spect and ammonia or rubidium for pet. Each type of test has its own possible pitfalls. Artifacts are often the case of false positive. ...Read more
What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.
Nuclear/ Echo stress: Lexiscan stress generally performed with nuclear isotope, which shows blood circulation(perfusion), comparing with medication lexiscan(stressing heart) and at rest. Dobutamine echo we are looking at wallmotion of heart with medication dobutamine( stressing heart )and at rest to see they show any differences to detect blockages ...Read moreSee 2 more doctor answers
Many things. : The echocardiogram or heart ultrasound, gives an accurate picture of the heart's anatomy. An ekg demonstrates the cardiac rhythm. A holter moniters the cardiac rhythm over time- say 12 or 24 hours. These measure different aspects of heart function and are helpful in assessing heart function thoroughly. ...Read more
I have had regular stress test. Nuclear stress test echocardiogram and heart catherization. All normal what's chance missed blockage or pulm htn?
Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...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
