Graham Barnett Thursday Nov. 2 2006 Carly Kruchten-Sheridan Group #5 Poev Touch Lab Report – Session 8 –Coronary Vascular Disease SET I: 1) In the 1 st tape a patient is given a stress test & his ECG is monitored. What type of change in his ECG pattern is the physician looking for? Can you think of a non- ECG response that might occur during a stress test? In the stress test the patient is hooked up and monitored for change in heart activity while exercising (using a treadmill). The ECG is a non - invasive way to diagnose & evaluate cardiac disorders. The patient’s ECG is then monitored, looking at changes in comparison to their normal heart rate, heart rhythm, heart pathology (hypertrophy, ischemia, MI) & blood pressure. Some non-ECG responses that might occur during the stress test are, cramping, asthmatic or respiratory changes & dizziness or cognitive changes. 2) What is a thallium test & how does it work? What type of information does it give a clinician about the cardiovascular system? A thallium test is a form of a stress test. This is a blood flow agent. Thallium is an element that is used as a nuclear tracer as it is radioactive. It is injected at the peak of exercise to show how well the blood flow (or myocardial perfusion) is in a specific area of the heart. This is good for baseline EKG. The thallium test is useful to clinicians as it can help show the extent of any coronary artery blockage, any causes of chest pain (angina), and the level of exercise the patient can safely handle. It can also help determine the prognosis of patients who’ve previously had a heart attack. 3) What are the symptoms of a heart attack?
