CARDIAC STRESS
DEFINE NONINVASIVE
MEANING THAT IT DOES NOT REQUIRE ENTRANCE INTO A BODY CAVITY, TISSUE, OR BLOOD VESSEL
Cardiac Vasodilator
Causes rapid increase in coronary blood flow in normal coronary arteries with little or no stenotic (narrow) arteries.
WHAT IS A STRESS ECHOCARDIOGRAM
A test that combines an exercise stress test with an echocardiogram to assess left ventricular wall motion both before and immediately after exercise
WHAT IS A RADIOLOGIST?
A physician who specializes in the use of radioactive substances to diagnose and treat disease
What is HTN (Hypertension)?
HIGH BLOOD PRESSURE
What does CVD stand for?
Coronary Vascular Disease
What is Adenocard?
Cardica Vasodilator
Causes the dilation of coronary vessels which results in increased blood velocity & flow rate in the vessels of a response in stenotic (narrow) vessels
What is Gate?
A selective technique in which a gamma camera is triggered by specific events captured by a three-lead ECG MONITOR
What is CONGESTED HEART FAILURE?
Failure of the heart to pump an adequate amount of blood to the body tissues
What is a skin rasp?
A rough piece of material (similar to sand paper) used to abrade (scrape) the skin prior to electrode placement
WHY IS EXERCISE ELECTROCARDIOGRAPHY USED?
What is Persantine?
Cardiac Vasodilator. Causes the coronary vessels to dilate
What is a gamma Camera?
A camera that records the gamma radiation emitted by the radioactive tracers in a patients blood
WHAT DOES CPR STAND FOR?
What is Target hear rate (THR)?
Heart rate measurement needed to truly exercise the heart
WHAT DEOS A DEPRESSED ST SEGMENT IDENTIFY?
MYOCARDIAL ISCHEMIA
WHAT IS DOBUTAMINE?
WHAT IS A NUCLEAR STRESS TEST?
A stress test in which radionuclides (radioactive tracers) are administered to trace the path of blood through the heart
What is a False Postive?
When a diagnostic test inidicates that disease is present but, in reality, no disease is present. A false positive is never considered a negative result. It is a positive result, albeit a falsely positive one
Target heart of 220 minus the age mulitplied by a percentage between 60 to 85
THR=(220-age) x 0.60 to
THR= (220-age x 0.85)
WHAT IS A CHEMICAL STRESS TEST?
IS USED WHEN THE PATIENT IS UNABLE TO RUN OR WALK ON A TREADMILL OR USE AN EXERCISE BIKE DUE TO AGE, INJURY OR PHYSICAL DEFECT
WHAT IS A NUCLEAR STRESS TEST?
TECHNOLOGIST FIRST INJECTS THE PATIENT WITH A STRESSING CHEMICAL, THEN A RADIOACTIVE TRACER
WHAT IS SICK SINUS SYNDROME?
A disease that affects the function of the SA NODE. It can result in bradycardia, tachycardia, or even cause pauses in the conduction such as sinus arrest.
What is maximum exercise?
Target Heart Rate of 220 minus the age of the patient
What is Rate Pressure Product (RPP) ?
Systolic Blood pressure multiplied by the heart rate; also known as doue product
This in one technique used to estimate oxygen utilization or myocardial work
