How does caffiene effect stress test?

Increase rate or PVC: Most of the time, caffeine has no adverse effects when used in moderation, and if individuals not sensitive to it, in which cases, leads to increased heart rate, slight inc bp, increase extra (ectopic) beats (pac or pvc's). If caffeine in those people take a stress test, resting pulse is increased and therefore, pulse with exercise is also. Speak with cardiologist doing the testing. ...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

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

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

Day 4 heart skipping and palpitation stress test came back good and im not dehydrated what could be wrong? No alcohol, caffeine or drugs. On monitor

Day 4 heart skipping and palpitation stress test came back good and im not dehydrated what could be wrong? No alcohol, caffeine or drugs. On monitor

Hard to say: You say you're on a monitor. I am assuming the results are not back yet. If the skip beats and palpitations occur while you are on the monitor then a record is made and your cardiologist should be able to get a better idea of what is going on. Many have ways for you to mark when you have symptoms, too. An electrophysiologist (heart rhythm specialist) should be able to help. ...Read more

For job I must rank top5% at cardiac stress test. Can a supplement with caffeine, theobromine, quercetin cause problems with healthy heart (ekg normal)?

What does a non-stress test consist of?

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

Can a nuclear stress test cause you problems?

Can a nuclear stress test cause you problems?

Typically not: The only "risk" would be during the stress part, when one runs on a treadmill or gets a drug alternative. However, there is little risk here because this is monitored with an ekg and supervised by a cardiologist/nuclear physician. One drug that is used for stress even has an agent that can reverse its side effects. In summary, under normal standard-of care-conditions, there should be little risk. ...Read more

What is tested for during an exercise stress test?

What is tested for during an exercise stress test?

Coronary reserve: As a stress test progresses, the heart beats harder and faster which requires a richer and richer circulation provided by the coronary arteries. If need outstrips supply due to blockage, the test becomes abnormal. Thus a stress test is an indirect way to look for blockage. (a direct way is to fill the coronaries with dye and observe them directly) ...Read more
